I am installing gitlab. when I installed GitLab shell, I got the errors:rake about....But I still can not figure it out after trying many ways.
After I executed the command "sudo -u git -H bundle exec rake gitlab:shell:install[v2.6.5] REDIS_URL=unix:/var/run/redis/redis.sock RAILS_ENV=production"
the error is : /usr/local/lib/ruby/gems/2.1.0/gems/rouge-1.9.1/lib/rouge/lexers/shell.rb:20: warning: already initialized constant Rouge::Lexers::Shell::KEYWORDS

But when I run "gem list", the result shows that I have installed shwon below, mysql2 (0.4.1)
