  • centos安装youcompleteme

    哈哈,我又回来了,简单的重新装了一边虚拟机,又把vim配置了一遍,这回有信心把youcomplete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

    http://www.centoscn.com/image-text/install/2016/0424/7115.html

    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

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

    备用:git clone https://github.com/gmarik/vundle.git
    • 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~
