ruby - 如何更改默认的 gem 版本

Question

如有任何帮助，我们将不胜感激!

我在运行 bundle 更新后尝试重新配置我的 GitLab。但是遇到了下面列出的错误。

大多数时候报告这种类型的错误，错误中会列出与之冲突的 gem，但我的只是说它与 chef 有问题，所以我不确定这里真正的问题是什么.

此时我正在全新安装 GitLab。我刚刚毫无问题地运行了 bundle 更新。尝试运行 Gitlab-ctl reconfigure 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

已安装的 JSON 版本: json (1.8.1)

我试过:

• 捆绑安装
• bundle 更新
• 安装较新版本的 json (1.8.2) 然后卸载旧的 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

• 卸载并重新安装 ruby​​
• 设置默认 ruby
• 将 json 添加到 Gemfile

  gem "json", "~> 1.8.1"

• 编辑 Gemfile.lock 以使用正确的 json
• 删除了 Gemfile.lock

错误:

我从 GitLab 支持人员那里了解到，运行 bundle 更新会破坏许多 GitLab 依赖项。
