我尝试使用此处发布的解决方案：GitLab v5.0 git push questions to fix the ssh keys getting out of sync 问题。
但是，当我在存储库服务器上以&用户的身份运行rake命令时，我收到以下消息：rootgit
root@gitlab /home/git# rake gitlab:shell:setup RAILS_ENV=production --TRACE
No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb)

该rake命令应该如何用于解决同步问题？
