yeoman install

install

Usage: yeoman install <packageName>, yeoman install <package1> <package2>

Installs a package and any packages that this depends on using Twitter Bower. A package is a folder containing a resource described by a package.json file or a gzipped tarball containing this information.

By default, running yeoman install packageName will install the dependency in your projects app/bower_components folder.

Example:

yeoman install backbone

# or if you wish to install multiple packages at once..
yeoman install jquery spine

As mentioned, the files for these dependencies will be added to app/bower_components. If you wish to use any of them you will need to manually include a script/file reference to the relevant source files.

Example:

<script src="bower_components/spine/lib/spine.js"></script>

If installing a dependency which has its own dependencies described, these dependencies will also be pulled in.

Example:

yeoman install backbone

will actually also install Underscore.js and jQuery.js as these are required for Backbone to function correctly.

yeoman install also supports installing packages using more than just the package name. Namely:

yeoman install jquery
yeoman install git://github.com/components/jquery.git
yeoman install components/jquery (same as above)
yeoman install http://foo.com/jquery.awesome-plugin.js
yeoman install ./repos/jquery

As you can see, packages can be installed by name, Git endpoint, GitHub shorthand, URL or local path. If you install and URL that is a zip or tar file, yeoman will automatically extract the contents of it. When tags are available in the endpoint, you can specify a semver tag to fetch concrete versions:

yeoman install jquery#1.8.1
yeoman install git://github.com/components/jquery.git#~1.8.1
yeoman install components/jquery#1.8.x
