如何更改默认 gem 版本

Question

如有任何帮助，我们将不胜感激！

我尝试在运行捆绑包更新后重新配置我的 GitLab。但是运行进入下面列出的错误。

大多数时候报这种类型的错误会在错误中列出与之冲突的gem，但我的只是说它与厨师有问题，所以我不确定真正的问题是什么。

此时我正在全新安装 GitLab。我刚刚运行一个没有问题的捆绑包更新。尝试运行 Gitlab-ctl 重新配置并得到下面列出的错误。

Ruby 版本： ruby 2.2.0p0（2014-12-25 修订版 49005）[x86_64-linux]

RVM 版本： rvm 1.26.10

已安装 JSON 版本： json (1.8.1)

我试过：

捆绑安装
捆绑包更新
安装新版本 json (1.8.2) 然后卸载旧版本 json
- 当我尝试卸载版本 1.8.1 时出现以下错误：
  
  ERROR: While executing gem ... (Gem::InstallError) gem "json" cannot be uninstalled because it is a default gem
Uninstall and reinstall ruby
Set default ruby
Add json to the Gemfile

gem "json", "~> 1.8.1"
Edited the Gemfile.lock to use the correct json
Deleted the Gemfile.lock

Error:
