哈哈，我又回來了，簡單的重新裝了一邊虛擬機，又把vim配置了一遍，這回有信心把youcomplete的安裝方法貼出來了，先給個權威的鏈接，然後給出具體步驟，保證沒問題可以安裝成功
http://www.centoscn.com/image-text/install/2016/0424/7115.html
什麼是youcompleteme？就是一個強大的自動補全插件，安裝此插件之後配置一下vim，這樣在敲代碼的時候就不會有忘記函數名的尴尬了~
我們需要以下幾步
yum install python
1git clone https://github.com/gmarik/Vundle.vim.git~/.vim/bundle/Vundle.vim
在vimrc中添加這樣的配置語句
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
去github上clone一下youcompleteme的代碼
git clone https://github.com/Valloric/YouCompleteMe.git ~/.vim/bundle/YouCompleteMe
然後在vim裡面安裝一下，執行
:PluginInstall
看到有DONE!顯示就好了
這一步坑了我好久，網上好多抄襲的全是apt命令和dnf命令，不太適合我的centos7，用yum就好了！
yum install automake gcc gcc-c++ kernel-devel cmakeyum install python-devel python3-devel
不管安沒安裝python在這兩句命令執行之後你都有了
接下來就是編譯的重頭戲
cd ~/.vim/bundle/YouCompleteMe./install.py --clang-completer
執行以上兩句命令，然後等待就好了~編譯就好了
修改vimrc文件
let g:ycm_global_ycm_extra_conf = '/home/li/.vim/bundle/YouCompleteMe/.ycm_extra_conf.py let g:ycm_seed_identifiers_with_syntax=1 " 語法關鍵字補全 let g:ycm_confirm_extra_conf=0 " 打開vim時不再詢問是否加載ycm_extra_conf.py配置 inoremap <expr> <CR> pumvisible() ? "\<C-y>" : "\<CR>" "回車即選中當前項 set completeopt=longest,menu "讓Vim的補全菜單行為與一般IDE一致(參考VimTip1228)
注意第一句，/home/li/這部分不一定通用，根據自己當前登陸的賬戶來定，我的使用root登陸的，所以這部分就是/root/
有可能.ycm_extra_conf.py這個文件會自動就有，也許會沒有，find一下，沒找到的話就自己vim修改一下，以下是該文件內容，復制之前，友情提示，在vim輸入
：set paste
進入復制模式，這樣子復制之後格式就不會亂了~
