Gitlab PUSH syntax error, unexpected ':', expecting $end

Question

I've installed Gitlab 5, all ran smoothly until I attempted to make a test PUSH. The error is:

remote: /usr/local/rvm/gems/ruby-2.0.0-p0/gems/bundler-1.3.5/lib/bundler/dsl.rb:33:in `eval_gemfile': Gemfile syntax error: (Bundler::GemfileError)        
remote: /home/git/gitlab/Gemfile:14: syntax error, unexpected ':', expecting $end        
remote: gem "mysql2", group: :mysql        
remote:                     ^          

I searched all over the internet (well, kind of), but mostly the answer is about using a lower version of ruby (1.8.7). Which is not the case here, as you can see, I'm using 2.0.0-p0.

I'm attaching the Gemfile as well, which is from Gitlab source code, so I reckon there's nothing wrong with it. Just in case:

source "https://rubygems.org"

def darwin_only(require_as)
  RUBY_PLATFORM.include?('darwin') && require_as
end

def linux_only(require_as)
  RUBY_PLATFORM.include?('linux') && require_as
end

Could anyone help? Thanks in advance.

Answer 1

Solved this. Somehow Gitlab gems (bundles?) still used the system ruby (1.8.7). I had to yum remove it, and things work now.

Answer 2

As mentioned in Issue 3080 and in the GitLab requirement section:

ruby 1.9.3

I would try first switching to ruby1.9.3 (certainly not 1.8.x).

Answer 3

After spending around 3 hours on exactly same problem, solution was as given by : An Phan

Do $ rpm -qa | grep -i ruby

It will give you like ruby.1.8..*

DO yum erase ruby.1.8..*
