CentOS安装YouCompleMe

重新安装了一遍虚拟机,又把Vim配置了一遍,这回有信心把YouCompleMe的安装方法贴出来了,先给个权威的链接,然后给出具体步骤,保证没问题可以安装成功

什么是youcompleteme?就是一个强大的自动补全插件,安装此插件之后配置一下vim,这样在敲代码的时候就不会有忘记函数名的尴尬了~

我们需要以下几步

先检查一下自己的虚拟机中是否有安装python,用vim试一下1 :echo has(‘python’) 如果得到结果为1 就说明有(其实有没有都无所谓,再执行一遍安装命令绝对没错)

yum install python

安装vundle,vundle是一款vim插件管理工具,使用它安装youcomplete很简单

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

配置vundle

在vimrc中添加这样的配置语句

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

安装youcompleteme

去github上clone一下youcompleteme的代码

git clone https://github.com/Valloric/YouCompleteMe.git ~/.vim/bundle/YouCompleteMe

然后在vim里面安装一下,执行

:PluginInstall

看到有DONE!显示就好了

编译youcomplete

这一步坑了我好久,网上好多抄袭的全是apt命令和dnf命令,不太适合我的CentOS7,用yum就好了!

yum install automake gcc gcc-c++ kernel-devel cmake
yum install python-devel python3-devel

不管安没安装python在这两句命令执行之后你都有了

接下来就是编译的重头戏

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

执行以上两句命令,然后等待就好了~编译就好了

配置vim

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    ” 语法关键字补全 
let g:ycm_confirm_extra_conf=0  ” 打开vim时不再询问是否加载ycm_extra_conf.py配置 
inoremap <expr> <CR>  pumvisible() ? “\<C-y>” : “\<CR>”    “回车即选中当前项 
set completeopt=longest,menu    “让Vim的补全菜单行为与一般IDE一致(参考VimTip1228) 

注意第一句,/home/li/这部分不一定通用,根据自己当前登陆的账户来定,我的使用root登陆的,所以这部分就是/root/
•(可能会有)附件

有可能.ycm_extra_conf.py这个文件会自动就有,也许会没有,find一下,没找到的话就自己vim修改一下,以下是该文件内容,复制之前,友情提示,在vim输入

:set paste

进入复制模式,这样子复制之后格式就不会乱了~
