Gitlab push - rubygems error

Question

I am using gitlab as our local repository, but when i am pushing something into it, it tells me that i have something wrong with installed gems. I am not a Ruby programmer.

Do you have some tips on how to fix it?

Here is the problem:

remote: /usr/local/lib/ruby/gems/2.1.0/gems/bundler-1.6.5/lib/bundler/dsl.rb:39:in
`eval_gemfile': Gemfile syntax error compile error (Bundler::GemfileError)
remote: on line 23: syntax error, unexpected ':', expecting $end
remote: gem "mysql2", group: :mysql
remote:                     ^

remote:     from /usr/local/lib/ruby/gems/2.1.0/gems/bundler-1.6.5/lib/bundler.rb:116:in `setup'
remote:     from /usr/local/lib/ruby/gems/2.1.0/gems/bundler-1.6.5/lib/bundler/setup.rb:17
remote: error: hook declined to update refs/heads/master

I tried to re-install all gems, but nothing changed. Do you have some tips, where the problem is?

Answer 1

Make sure you're running the code with Ruby >= 1.9. This hash syntax is not supported in older versions.
