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. It resolves circular dependencies by talking to the npm registry.
<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
In order to distinguish between this and remote installs, the argument must either be "." or contain a "/" in it.
npm install ./package.tgz
<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 http://github.com/waveto/node-crypto/tarball/v0.0.5
<name>: Do a
<tag>is the "tag" config from either your .npmrc file, or the --tag argument on the command line.
npm install sax
<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
<name>@<version>: Install the specified version of the package. This will fail if the version has not been published to the registry.
npm install firstname.lastname@example.org
<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
--tag argument will apply to all of the specified install targets.
--force argument will force npm to fetch remote resources even if a local copy exists on disk.
npm install sax --force

If you ask npm to install a package and don't tell it a specific version, then it will install the specified tag.
Note: this has no effect on the npm-tag(1) command.
If set to a truish value, then it'll install the "devDependencies" as well as "dependencies" when installing a package.
