NAME
virtualenv - create virtual Python instances
SYNOPSIS
virtualenv [options...] [destination-directory]
DESCRIPTION
virtualenv creates virtual Python executables, each of which can have its own set of installed modules.
Programs that require different versions of modules or sets of modules that may be incompatible with
others to be installed on the same system without conflicts.
The result is a directory containing its own Python executables (in DIR/bin/pythonVER and DIR/bin/python)
and its own module directory containing the standard library as installed by the system. Additional
modules may be installed via setuptools, as invoked from the binary directory (DIR/bin/easy_install). The
system´s site-packages directories will not be available by default, but can be made visible with the
--system-site-packages option. They can then be overridden with locally-installed modules.
In addition, a shell script called "activate" will be installed in the bin directory. If sourced, this
will cause normal invocations of the Python executable to use the virtual environment.
By running the virtualenv command explicitly under the desired Python interpreter, the user can control
which version of Python is created in the virtual environment.
OPTIONS
-h, --help
Show summary of options.
--version
Show the version of the program.
-v, --verbose
Be more verbose.
-q, --quiet
Be less verbose; suppress unimportant output.
--clear
Clear out a previously-created virtual Python instance in this location before creating a new one.
-p PYTHON_EXE,--python=PYTHON_EXE
The Python interpreter to use to create the new environment.
--no-site-packages
Ignored (the default). Don´t give access to the global site-packages modules to the virtual
environment.
--system-site-packages
Give access to the global site-packages modules to the virtual environment.
--always-copy
Always copy files rather than symlinking.
--unzip-setuptools
Unzip Setuptools when installing it. This fixes up scripts and makes all .pth files relative.
--relocatable
Make an EXISTING virtualenv environment relocatable.
--no-setuptools
Do not install setuptools (or pip) in the new virtualenv.
--no-pip
Do not install pip in the new virtualenv.
--extra-search-dir=SEARCH_DIRS
Directory to search for setuptools/distribute/pip distributions in. Can be specified multiple times.
--prompt==PROMPT
Provides an alternative prompt prefix for this environment.
