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. The filename must use .tar, .tar.gz, or .tgz as the extension.
Example:npm install ./package.tgz
npm install --save-dev flow-bin же.
