CentOs 7下vim安裝YouCompleteMe外掛程式

CentOs 7下vim安裝YouCompleteMe外掛程式

最權威的原始步驟可以參考github中關於此外掛程式的README.md，如果時間允許的話，盡量多看幾遍可以避免很多不必要的麻煩。

一.版本檢測

使用vim --version指令，檢 vim版本是否大於7.3.584，一般新系統都滿足。開啟vim，輸入下述指令查看是否支援Python。如果顯示為1，則表示支援python；如果顯示為0，則表示不支援python，需要重新下載編譯vim，使其支援python。

:echo has('python')

二.下載Vundle和YouCompleteMe外掛程式

輸入以下指令，下載Vundle

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

下載成功後，在使用者根目錄下面，修改.vimrc檔案，追加下面語句以便後續安裝YouCompleteMe外掛程式

set nocompatible  filetype off  set rtp+=~/.vim/bundle/Vundle.vim  call vundle#begin()  Plugin 'gmarik/Vundle.vim'  Plugin 'Valloric/YouCompleteMe'  call vundle#end()  filetype plugin indent on  

然後在vim中先按Esc建，並且輸入以下指令安裝外掛程式：

:PluginInstall 

三.編譯YouCompleteMe

在編譯之前下載編譯工具，準備編譯YouCompleteMe

sudo dnf install automake gcc gcc-c++ kernel-devel cmakesudo dnf install python-devel python3-devel

編譯YouCompleteMe使其支援C/C++ 自動補全

cd ~/.vim/bundle/YouCompleteMe./install.py --clang-completer

四.配置vim

修改.vimrc檔案

let g:ycm_global_ycm_extra_conf = '/home/li/.vim/bundle/YouCompleteMe/.ycm_extra_conf.py  let g:ycm_seed_identifiers_with_syntax=1    " 文法關鍵字補全  let g:ycm_confirm_extra_conf=0   " 開啟vim時不再詢問是否載入ycm_extra_conf.py配置  inoremap <expr> <CR>  pumvisible() ? "\<C-y>" : "\<CR>"    "斷行符號即選中當前項  set completeopt=longest,menu    "讓Vim的補全菜單行為與一般IDE一致(參考VimTip1228)
