Anaconda3 带有 jedi-vim、Manjaro linux、ImportError，无法导入“jedi”Python 模块

Question

我在使用 anaconda3 python 发行版和 jedi-vim 插件时遇到了这个奇怪的错误。以下是 :JediDebugInfo 的输出

#### Jedi-vim debug information

##### Settings

```
  omnifunc=python3complete#Complete
        Last set from /usr/share/vim/vim81/ftplugin/python.vim line 41

        Last set from /usr/share/vim/vimfiles/plugin/jedi.vim line 31
```

我已经运行命令：conda update --all对于 anaconda3 和:PluginUpdate对于 vim（我使用 Vundle 来安装 jedi-vim）。
