Require local gem ruby

I have a gem that I created in Ruby on my local machine and I need to require this gem in a plain Ruby script that starts a service.

I have to require like this:

require_relative '../../../my-gem/lib/my/gem'

Is it possible to do this require without putting in the relative path?

If you have a gem, you can install it and set the version you want (in my example 1.0.0.beta) with gem 'my-gem', '= 1.0.0.beta'.

But I think yu look for another solution:

You can extend the location where require looks:

$:.unshift('../../../my-gem/lib')
require('my/gem')

or

$LOAD_PATH.unshift('../../../my-gem/lib')
require('my/gem')

You could also use $: << '../../../my-gem/lib', but I prefer unshift. If your gem contains a file with similar names as in a gem (avoid it!), then unshift guarantees your script is loaded.

require checks for files in $LOAD_PATH. You can put your gem in one of those directories in order to require it directly. If you don't like your load path, you can add a new directory to it in your script, or set the RUBYLIB environment variable which is added to the load path.
