jedi.vim怎么使用？

要使用jedi-vim插件，需要按照以下步骤进行配置：

1. 安装vim插件管理器vundle。在终端中输入以下命令进行安装：

   git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

2. 在vim配置文件~/.vimrc中添加以下内容：

   set nocompatible              " be iMproved, required
   filetype off                  " required
   
   " set the runtime path to include Vundle and initialize
   set rtp+=~/.vim/bundle/Vundle.vim
   call vundle#begin()
   
   " let Vundle manage Vundle, required
   Plugin 'VundleVim/Vundle.vim'
   
   " The following are examples of different formats supported.
   " Keep Plugin commands between vundle#begin/end.

   Plugin 'davidhalter/jedi-vim'
   
   call vundle#end()            " required
   filetype plugin indent on    " required
   
   " To ignore plugin indent changes, instead use:
   "filetype plugin on
   "
   " Brief help
   " :PluginList       - lists configured plugins
   " :PluginInstall    - installs plugins; append `!` to update or just :PluginUpdate
   " :PluginSearch foo - searches for foo; append `!` to refresh local cache
   " :PluginClean      - confirms removal of unused plugins; append `!` to auto-approve removal
   "
   " see :h vundle for more details or wiki for FAQ
   " Put your non-Plugin stuff after this line

3. 保存并退出vim配置文件，然后在vim中输入以下命令安装插件：

   :PluginInstall

4. 安装完成后，可以使用jedi-vim插件提供的自动补全功能。在vim中输入以下命令开启自动补全：

   :set omnifunc=jedi#completions

然后在编辑Python文件时，输入`.`或者`<C-Space>`即可触发自动补全。
