Ubuntu 14.04下Vim安装YouCompleMe插件

最权威的原始步骤可以参考github中关于此插件的，如果时间允许的话，尽量多看几遍可以避免很多不必要的麻烦。

版本检测，一般新系统都满足，保证Vim>= 7.3.584，支持python就可以了。

第一步：下载Vundle和YouCompleteMe插件

输入以下指令，下载Vundle

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

下载成功后，在用户根目录下面，修改.vimrc文件，追加下面语句：

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

然后在vim中先按Esc建，并且输入以下指令安装插件：

:PluginInstall

或在终端中输入：

vim +PluginInstall +qall

第二步：下载其他必要文件

• 下载最新版本的

强烈建议下载已经编译好的二级制文件包，如果下载源文件自己编译的话，你永远都不知道会出什么奇葩错误

然后解压到指定文件夹，过程如下：

cd ~mkdir ycm_tempcd ycm_tempxz -d clang+llvm-3.6.0-x86_64-linux-gnu--14.04.tar.xztar -xvf clang+llvm-3.6.0-x86_64-linux-gnu-ubuntu-14.04.tar

修改clang+llvm-3.6.0-x86_64-linux-gnu文件夹名字为llvm_root_dir

• 下载最新版本的

强烈建议下载已经编译好的二级制文件包，如果下载源文件自己编译的话，你永远都不知道会出什么奇葩错误

然后将cmake连接至/usr/bin，比如我的是放在Downloads文件夹下面的，就地解压，并链接

tar zxvf cmake-3.2.2-Linux-x86_64.tar.gzln -s /home/li/Downloads/cmake-3.2.2/bin/cmake /usr/bin/cmake

第三步：编译文件

运行如下指令，编译文件

cd ~mkdir ycm_buildcd ycm_buildcmake -G "Unix Makefiles" -DPATH_TO_LLVM_ROOT=~/ycm_temp/llvm_root_dir . ~/.vim/bundle/YouCompleteMe/third_party/ycmd/cppmake ycm_support_libs 

这样以来，就算是安装基本上完成了。

第四步：配置vim

虽然安装编译完成了，但距离成功还差一步，配置vim（修改.vimrc），这个根据需要配置便可，比如我的如下：

let g:ycm_global_ycm_extra_conf = '/home/li/.vim/bundle/YouCompleteMe/.ycm_extra_conf.pylet 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) 

出现的问题：

• E492: Not an editor command:

可能的原因有很多，比如我遇到的是权限问题，为.vim的追加写入权限

• 不能正常启动，有很多红色的错误

可能的原因同样很多，比如我遇到的是使用编译器版本不合适，比如gcc5.1.0编译运行完成之后，错的不知其所以然

• 没有.ycm_extra.conf.py文件

可以参考自己修改或者直接使用它亦或者使用我的(见附件)。将它放在项目根目录或者指定目录，比如我放在

$HOME/.vim/bundle/YouCompleteMe/.ycm_extra_conf.py

当然记得修改.vimrc中相应的那行哦！

• 出现其他未知错误

vim中输入

:YcmDebugInfo

查看相关信息

• 如果完全按照本教程步骤来，还是出现了大量错误

此时要做的不是搜索其他教程，而是详细阅读
