Install the listed gems and their dependencies using command
$ bundle install
If Gemfile.lock is not present and bundle install is run for the first time, all remote sources are fetched, dependencies are resolved and all needed gems are installed.
If Gemfile.lock is present bundler will use all gem versions specified in Gemfile.lock instead of resolving dependencies. In case Gemfile is updated, bundler will re-resolve dependencies for updated gems and use versions from Gemfile.lock for gems which were not updated. [1]
Checkin Gemfile.lock to your repository so that other developers of the application use same version of the third party code. [2]
