NAME

       cargo-install - Build and install a Rust binary

SYNOPSIS

       cargo install [options] crate[@version]...
       cargo install [options] --path path
       cargo install [options] --git url [crate...]
       cargo install [options] --list

DESCRIPTION

       This command manages Cargo's local set of installed binary crates. Only packages which
       have executable [[bin]] or [[example]] targets can be installed, and all executables are
       installed into the installation root's bin folder.

       The installation root is determined, in order of precedence:

       •  --root option

       •  CARGO_INSTALL_ROOT environment variable

       •  install.root Cargo config value <https://doc.rust-lang.org/cargo/reference/config.html>

       •  CARGO_HOME environment variable

       •  $HOME/.cargo

       There are multiple sources from which a crate can be installed. The default location is
       crates.io but the --git, --path, and --registry flags can change this source. If the
       source contains more than one package (such as crates.io or a git repository with multiple
       crates) the crate argument is required to indicate which crate should be installed.

       Crates from crates.io can optionally specify the version they wish to install via the
       --version flags, and similarly packages from git repositories can optionally specify the
       branch, tag, or revision that should be installed. If a crate has multiple binaries, the
       --bin argument can selectively install only one of them, and if you'd rather install
       examples the --example argument can be used as well.

       If the package is already installed, Cargo will reinstall it if the installed version does
       not appear to be up-to-date. If any of the following values change, then Cargo will
       reinstall the package:

       •  The package version and source.

       •  The set of binary names installed.

       •  The chosen features.

       •  The profile (--profile).

       •  The target (--target).

       Installing with --path will always build and install, unless there are conflicting
       binaries from another package. The --force flag may be used to force Cargo to always
       reinstall the package.

       If the source is crates.io or --git then by default the crate will be built in a temporary
       target directory. To avoid this, the target directory can be specified by setting the
       CARGO_TARGET_DIR environment variable to a relative path. In particular, this can be
       useful for caching build artifacts on continuous integration systems.

       By default, the Cargo.lock file that is included with the package will be ignored. This
       means that Cargo will recompute which versions of dependencies to use, possibly using
       newer versions that have been released since the package was published. The --locked flag
       can be used to force Cargo to use the packaged Cargo.lock file if it is available. This
       may be useful for ensuring reproducible builds, to use the exact same set of dependencies
       that were available when the package was published. It may also be useful if a newer
       version of a dependency is published that no longer builds on your system, or has other
       problems. The downside to using --locked is that you will not receive any fixes or updates
       to any dependency. Note that Cargo did not start publishing Cargo.lock files until version
       1.37, which means packages published with prior versions will not have a Cargo.lock file
       available.

OPTIONS

   Install Options
       --vers version, --version version
           Specify a version to install. This may be a version requirement
           <https://doc.rust-lang.org/cargo/reference/specifying-dependencies.md>, like ~1.2, to
           have Cargo select the newest version from the given requirement. If the version does
           not have a requirement operator (such as ^ or ~), then it must be in the form
           MAJOR.MINOR.PATCH, and will install exactly that version; it is not treated as a caret
           requirement like Cargo dependencies are.

       --git url
           Git URL to install the specified crate from.

       --branch branch
           Branch to use when installing from git.

       --tag tag
           Tag to use when installing from git.

       --rev sha
           Specific commit to use when installing from git.

       --path path
           Filesystem path to local crate to install.

       --list
           List all installed packages and their versions.

       -f, --force
           Force overwriting existing crates or binaries. This can be used if a package has
           installed a binary with the same name as another package. This is also useful if
           something has changed on the system that you want to rebuild with, such as a newer
           version of rustc.

       --no-track
           By default, Cargo keeps track of the installed packages with a metadata file stored in
           the installation root directory. This flag tells Cargo not to use or create that file.
           With this flag, Cargo will refuse to overwrite any existing files unless the --force
           flag is used. This also disables Cargo's ability to protect against multiple
           concurrent invocations of Cargo installing at the same time.

       --bin name...
           Install only the specified binary.

       --bins
           Install all binaries.

       --example name...
           Install only the specified example.

       --examples
           Install all examples.

       --root dir
           Directory to install packages into.

       --registry registry
           Name of the registry to use. Registry names are defined in Cargo config files
           <https://doc.rust-lang.org/cargo/reference/config.html>. If not specified, the default
           registry is used, which is defined by the registry.default config key which defaults
           to crates-io.

       --index index
           The URL of the registry index to use.

   Feature Selection
       The feature flags allow you to control which features are enabled. When no feature options
       are given, the default feature is activated for every selected package.

       See the features documentation
       <https://doc.rust-lang.org/cargo/reference/features.html#command-line-feature-options> for
       more details.

       -F features, --features features
           Space or comma separated list of features to activate. Features of workspace members
           may be enabled with package-name/feature-name syntax. This flag may be specified
           multiple times, which enables all specified features.

       --all-features
           Activate all available features of all selected packages.

       --no-default-features
           Do not activate the default feature of the selected packages.

   Compilation Options
       --target triple
           Install for the given architecture. The default is the host architecture. The general
           format of the triple is <arch><sub>-<vendor>-<sys>-<abi>. Run rustc --print
           target-list for a list of supported targets.

           This may also be specified with the build.target config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

           Note that specifying this flag makes Cargo run in a different mode where the target
           artifacts are placed in a separate directory. See the build cache
           <https://doc.rust-lang.org/cargo/guide/build-cache.html> documentation for more
           details.

       --target-dir directory
           Directory for all generated artifacts and intermediate files. May also be specified
           with the CARGO_TARGET_DIR environment variable, or the build.target-dir config value
           <https://doc.rust-lang.org/cargo/reference/config.html>. Defaults to a new temporary
           folder located in the temporary directory of the platform.

           When using --path, by default it will use target directory in the workspace of the
           local crate unless --target-dir is specified.

       --debug
           Build with the dev profile instead the release profile. See also the --profile option
           for choosing a specific profile by name.

       --profile name
           Install with the given profile. See the the reference
           <https://doc.rust-lang.org/cargo/reference/profiles.html> for more details on
           profiles.

       --timings=fmts
           Output information how long each compilation takes, and track concurrency information
           over time. Accepts an optional comma-separated list of output formats; --timings
           without an argument will default to --timings=html. Specifying an output format
           (rather than the default) is unstable and requires -Zunstable-options. Valid output
           formats:

           •  html (unstable, requires -Zunstable-options): Write a human-readable file
               cargo-timing.html to the target/cargo-timings directory with a report of the
               compilation. Also write a report to the same directory with a timestamp in the
               filename if you want to look at older runs. HTML output is suitable for human
               consumption only, and does not provide machine-readable timing data.

           •  json (unstable, requires -Zunstable-options): Emit machine-readable JSON
               information about timing information.

   Manifest Options
       --frozen, --locked
           Either of these flags requires that the Cargo.lock file is up-to-date. If the lock
           file is missing, or it needs to be updated, Cargo will exit with an error. The
           --frozen flag also prevents Cargo from attempting to access the network to determine
           if it is out-of-date.

           These may be used in environments where you want to assert that the Cargo.lock file is
           up-to-date (such as a CI build) or want to avoid network access.

       --offline
           Prevents Cargo from accessing the network for any reason. Without this flag, Cargo
           will stop with an error if it needs to access the network and the network is not
           available. With this flag, Cargo will attempt to proceed without the network if
           possible.

           Beware that this may result in different dependency resolution than online mode. Cargo
           will restrict itself to crates that are downloaded locally, even if there might be a
           newer version as indicated in the local copy of the index. See the cargo-fetch(1)
           command to download dependencies before going offline.

           May also be specified with the net.offline config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

   Miscellaneous Options
       -j N, --jobs N
           Number of parallel jobs to run. May also be specified with the build.jobs config value
           <https://doc.rust-lang.org/cargo/reference/config.html>. Defaults to the number of
           logical CPUs. If negative, it sets the maximum number of parallel jobs to the number
           of logical CPUs plus provided value. Should not be 0.

       --keep-going
           Build as many crates in the dependency graph as possible, rather than aborting the
           build on the first one that fails to build. Unstable, requires -Zunstable-options.

   Display Options
       -v, --verbose
           Use verbose output. May be specified twice for "very verbose" output which includes
           extra output such as dependency warnings and build script output. May also be
           specified with the term.verbose config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

       -q, --quiet
           Do not print cargo log messages. May also be specified with the term.quiet config
           value <https://doc.rust-lang.org/cargo/reference/config.html>.

       --color when
           Control when colored output is used. Valid values:

           •  auto (default): Automatically detect if color support is available on the terminal.

           •  always: Always display colors.

           •  never: Never display colors.

           May also be specified with the term.color config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

       --message-format fmt
           The output format for diagnostic messages. Can be specified multiple times and
           consists of comma-separated values. Valid values:

           •  human (default): Display in a human-readable text format. Conflicts with short and
               json.

           •  short: Emit shorter, human-readable text messages. Conflicts with human and json.

           •  json: Emit JSON messages to stdout. See the reference
               <https://doc.rust-lang.org/cargo/reference/external-tools.html#json-messages> for
               more details. Conflicts with human and short.

           •  json-diagnostic-short: Ensure the rendered field of JSON messages contains the
               "short" rendering from rustc. Cannot be used with human or short.

           •  json-diagnostic-rendered-ansi: Ensure the rendered field of JSON messages contains
               embedded ANSI color codes for respecting rustc's default color scheme. Cannot be
               used with human or short.

           •  json-render-diagnostics: Instruct Cargo to not include rustc diagnostics in JSON
               messages printed, but instead Cargo itself should render the JSON diagnostics
               coming from rustc. Cargo's own JSON diagnostics and others coming from rustc are
               still emitted. Cannot be used with human or short.

   Common Options
       +toolchain
           If Cargo has been installed with rustup, and the first argument to cargo begins with
           +, it will be interpreted as a rustup toolchain name (such as +stable or +nightly).
           See the rustup documentation <https://rust-lang.github.io/rustup/overrides.html> for
           more information about how toolchain overrides work.

       --config KEY=VALUE or PATH
           Overrides a Cargo configuration value. The argument should be in TOML syntax of
           KEY=VALUE, or provided as a path to an extra configuration file. This flag may be
           specified multiple times. See the command-line overrides section
           <https://doc.rust-lang.org/cargo/reference/config.html#command-line-overrides> for
           more information.

       -h, --help
           Prints help information.

       -Z flag
           Unstable (nightly-only) flags to Cargo. Run cargo -Z help for details.
