npm-install(1) -- install a package


npm install (with no args in a package dir)
npm install <tarball file>
npm install <tarball url>
npm install <folder>
npm install <name>
npm install <name>@<tag>
npm install <name>@<version>
npm install <name>@<version range>


This command installs a package, and any packages that it depends on.

  • npm install (in package directory): Install the dependencies in the local node_modules folder.

    In global mode, it is the same as npm install $PWD

  • npm install <tarball file>: Install a package that is sitting on the filesystem. Note: if you just want to link a dev directory into your npm root, you can do this more easily by using npm link.

    In order to distinguish between this and remote installs, the argument must either be "." or contain a "/" in it.


    npm install ./package.tgz
  • npm install <tarball url>: Fetch the tarball url, and then install it. In order to distinguish between this and other options, the argument must start with "http://" or "https://"


    npm install
  • npm install <name>: Do a <name>@<tag> install, where <tag> is the "tag" config. (See npm help config)


    npm install sax
  • npm install <name>@<tag>: Install the version of the package that is referenced by the specified tag. If the tag does not exist in the registry data for that package, then this will fail.


    npm install sax@stable
  • npm install <name>@<version>: Install the specified version of the package. This will fail if the version has not been published to the registry.


    npm install sax@0.1.1
  • npm install <name>@<version range>: Install a version of the package matching the specified version range. This will follow the same rules for resolving dependencies described in npm help json.

    Note that most version ranges must be put in quotes so that your shell will treat it as a single argument.


    npm install sax@">=0.1.0 <0.2.0"

You may combine multiple arguments, and even multiple types of arguments. For example:

npm install sax@">=0.1.0 <0.2.0" bench supervisor

The --tag argument will apply to all of the specified install targets.

The --force argument will force npm to fetch remote resources even if a local copy exists on disk.

npm install sax --force
