Ruby on rails 更新系统后的RubyGems错误

在使用“sudo gem update--system”更新我的ruby设置之后尝试启动rails控制台时，我会发出

rails c

我得到这个错误：

有什么想法吗？

当你尝试列出你的珍宝时，你得到了什么。json>=1.4吗

e、 g:

如果您使用RVM gemset，您可能还需要列出它们，以检查默认gemset是否已更改：

rvm gemset list

编辑：谜团已解开！：-）

您不小心用sudo安装了gems——但您的用户帐户安装了RVM！

当您为单个用户安装了RVM时，通常执行sudo gem安装不是一个好主意，但是您应该只为本地用户安装gem，并让RVM管理它们

rvm gemset list

rvmsudo rvm get head

rvmsudo rvm get head

rvm use system
