缺少Neovim RubyGem

Question

我刚刚安装了neovim，我对RubyGem有问题。

“：CheckHealth”的输出表示缺少新的RubyGem：

## Ruby provider
  - ERROR: Missing Neovim RubyGem
      - SUGGESTIONS:
        - Install or upgrade the neovim RubyGem using `gem install neovim`.
  - INFO: Ruby Version: ruby 2.2.6p396 (2016-11-15 revision 56800) [x86_64-linux]
  - INFO: Host Executable: not found
  - INFO: Host Version: not found

安装'sudo gem install neovim‘后：

Successfully installed neovim-0.3.1
Parsing documentation for neovim-0.3.1
Done installing documentation for neovim after 0 seconds
1 gem installed

':CheckHealth‘的输出与之前相同：

## Ruby provider
  - ERROR: Missing Neovim RubyGem
      - SUGGESTIONS:
        - Install or upgrade the neovim RubyGem using `gem install neovim`.
  - INFO: Ruby Version: ruby 2.2.6p396 (2016-11-15 revision 56800) [x86_64-linux]
  - INFO: Host Executable: not found
  - INFO: Host Version: not found

我是不是遗漏了什么？我如何解决这个问题？

:echo has('ruby') returns 1

非常感谢。

编辑:这是'gem env‘的输出

如果您使用linux，请安装gem自定义安装并与sudo一起运行

请看这个可以帮助你设置路径

Answer 3

您可能需要将安装的gem的路径添加到您的路径中。

您可以在您的.bashrc或.bash_profile或其他shell的rc/profile文件中像下面这样做。[ -d $HOME/.gem/ruby/2.4.0/bin ] && PATH=$HOME/.gem/ruby/2.4.0/bin:$PATH

export PATH与所有其他路径值一起使用。
