Different Ruby Versions

We installed Ruby on /usr/local/bin/ruby (v2.1.6) from source.

The OS has installed version on /usr/bin/ruby (v2.0.0), which is in use by another application.

We get following Error Message while Merge Requests:

We tried out already to switch the Ruby Versions to /usr/bin/ruby as v2.1.6, which worked perfect, but the other application is not compatible to 2.1.6. So we have to switch it back.

Where can i find the configuration to change the Ruby location?

We changed the Shebang from the Gitlab-Shell scripts to the correct ruby version. It works now.
