在deepin上安装YouCompleteMe

详细安装步骤在github上有，https://github.com/Valloric/YouCompleteMe，我这里是自己总结的简化版安装步骤。

步骤1.安装Vundle

首先，clone到本地

• git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
• 把以下内容复制到.vimrc:

•   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()
    " alternatively, pass a path where Vundle should install plugins
    "call vundle#begin('~/some/path/here')
  
    " 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 on GitHub repo
    Plugin 'tpope/vim-fugitive'
    " plugin from http://vim-scripts.org/vim/scripts.html
    " Plugin 'L9'
    " Git plugin not hosted on GitHub
    Plugin 'git://git.wincent.com/command-t.git'
    " git repos on your local machine (i.e. when working on your own plugin)
    "Plugin 'file:///home/gmarik/path/to/plugin'
    " The sparkup vim script is in a subdirectory of this repo called vim.
    " Pass the path to set the runtimepath properly.
    Plugin 'rstacruz/sparkup', {'rtp': 'vim/'}
    " Install L9 and avoid a Naming conflict if you've already installed a
    " different version somewhere else.
    " Plugin 'ascenator/L9', {'name': 'newL9'}
  
    " All of your Plugins must be added before the following line
    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

• Install Plugins: 打开vim执行:PluginInstall 或者直接输入命令sudo vim +PluginInstall +qall

步骤2.安装工具和cmake

• sudo apt-get install build-essential cmake

步骤3.安装python-dev,python3-dev

• sudo apt-get install python-dev python3-dev

步骤4.安装clang

• sudo apt-get install clang

步骤5.编译

• cd ~/.vim/bundle/YouCompleteMe
• ./install.py --clang-completer
• 如果编译出错执行：git submodule update --init --recursive

步骤6.复制以下内容到.vimrc中

  "----------------------------"
  "------ YouCompleteMe -------"
  "----------------------------"
  let g:ycm_global_ycm_extra_conf = '~/.vim/bundle/YouCompleteMe/cpp/ycm/.ycm_extra_conf.py'

  " YouCompleteMe
  set runtimepath+=~/.vim/bundle/YouCompleteMe
  let g:ycm_collect_identifiers_from_tags_files =            " 开启 YCM 基于标签引擎
  let g:ycm_collect_identifiers_from_comments_and_strings =  " 注释与字符串中的内容也用于补全
  let g:syntastic_ignore_files=[".*\.py$"]
  let g:ycm_seed_identifiers_with_syntax =                   " 语法关键字补全
  let g:ycm_complete_in_comments =
  let g:ycm_confirm_extra_conf =
  let g:ycm_key_list_select_completion = ['<c-n>', '<Down>']  " 映射按键, 没有这个会拦截掉tab, 导致其他插件的tab不能用.
  let g:ycm_key_list_previous_completion = ['<c-p>', '<Up>']
  let g:ycm_complete_in_comments =                           " 在注释输入中也能补全
  let g:ycm_complete_in_strings =                            " 在字符串输入中也能补全
  let g:ycm_collect_identifiers_from_comments_and_strings =  " 注释和字符串中的文字也会被收入补全
  let g:ycm_global_ycm_extra_conf='~/.vim/bundle/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py'
  let g:ycm_show_diagnostics_ui =                            " 禁用语法检查
  inoremap <expr> <CR> pumvisible() ? "\<C-y>" : "\<CR>" |            " 回车即选中当前项
  nnoremap <c-j> :YcmCompleter GoToDefinitionElseDeclaration<CR>|     " 跳转到定义处
  "let g:ycm_min_num_of_chars_for_completion=2                 " 从第2个键入字符就开始罗列匹配项

步骤7.出现的错误

我安装完以后，出现了以下错误：

YouCompleteMe unavailable: requires Vim compiled with Python (2.6+ or 3.3+)

解决办法：编译安装vim8.0,添加python支持
