What's the Ruby analogue of npm link?

Question

If you the source for a Nodejs project, the command npm link installs it in such a way that any changes you make apply everywhere without you having to reinstall.

npm link is designed to install a development package and see the changes in real time without having to keep re-installing it.

Is there a analogue for Ruby projects?

Answer 1

The Ruby equivalent is to use the :path option when specifying a gem in your Gemfile. It would look something like this.

gem "mylocalgem", :path => "/path/to/local/gem/dir/"

If you are trying to do this globally on the default system ruby then you can do one of the following.

gem install --local path_to_gem/filename.gem

or just run the following from the directory where the .gem file exists and it will be picked up.

gem install
