NAME
npm-uninstall - Remove a package
Synopsis
npm uninstall [<@scope>/]<pkg>[@<version>]... [-S|--save|-D|--save-dev|-O|--save-optional|--no-save]
aliases: remove, rm, r, un, unlink
Description
This uninstalls a package, completely removing everything npm installed on its behalf.
Example:
npm uninstall sax
In global mode (ie, with -g or --global appended to the command), it uninstalls the current package
context as a global package.
npm uninstall takes 3 exclusive, optional flags which save or update the package version in your main
package.json:
• -S, --save: Package will be removed from your dependencies.
• -D, --save-dev: Package will be removed from your devDependencies.
• -O, --save-optional: Package will be removed from your optionalDependencies.
• --no-save: Package will not be removed from your package.json file.
Further, if you have an npm-shrinkwrap.json then it will be updated as well.
Scope is optional and follows the usual rules for npm help scope.
Examples:
npm uninstall sax --save
npm uninstall @myorg/privatepackage --save
npm uninstall node-tap --save-dev
npm uninstall dtrace-provider --save-optional
npm uninstall lodash --no-save
