vim 安装插件
1 简介
- 插件介绍：YouCompleteMe是一款针对Vim的快速，即用型的模糊搜索代码补全引擎。包括以下几种引擎：
- 基于标识符的引擎，可与每种编程语言一起使用
- 基于Clang的引擎，为C / C ++ / Objective-C / Objective-C ++（C系列）提供本地语义代码补全
- 基于Jedi的Python 2和3的补全引擎
- 基于OmniSharp的C＃补全引擎
- Go的Gocode和Godef语义引擎的组合，
- 基于TSServer的TypeScript完成引擎，
- 基于Tern的JavaScript补全引擎，
- 基于racer的Rust补全引擎，
- 基于jdt.ls的Java实验性补全引擎。
- 基于omnifunc的补全引擎，它使用来自Vim的omnicomplete系统的数据为许多其他语言（Ruby，PHP等）提供语义补全。
- 基于UltiSnips的代码片补全引擎

入坑vim多天后逐步装插件对vim进行完善，终于今天开始尝试装最牛插件之一YouCompleteMe。一路也是遇到不少问题，甚至想从源码编译，最后发现其实都是些小问题。
本系统为ubuntu
先上插件网址：https://github.com/Valloric/YouCompleteMe
1、
请确保有以下依赖
sudo apt install build-essential cmake python3-dev2、
这里用的是 vim-plug 下载，用vundle也差不多
-
call plug#begin('~/.vim/plugged')
-
Plug 'Valloric/YouCompleteMe', { 'do': './install.py --clang-completer'}
-
call plug#end()
然后漫长等待至下好，这个时候并不是结束，而是才刚刚开始
3、
cd ~/.vim/plugged/YouCompleteMe/ (就是找到安装目录）
一般这个时候都没有完整克隆下来的，执行命令
git submodule update --init --recursive
好像就可以完整安装下来
4、本文章的重点之一，就是这里开始遇到问题的
在YouCompleteMe目录下运行编译安装
-
cd ~/.vim/bundle/YouCompleteMe
-
./install.py --clang-completer
然后就惊奇发现终端有如下回复
CMake Error: The source directory "/home/rivalak/.cache/vimfiles/repos/github.com/Valloric/YouCompleteMe/third_party/ycmd/third_party/cregex" does not appear to contain CMakeLists.txt.
其实这是因为 ~/.vim/plugged/YouCompleteMe/third_party/ycmd/third_party/cregex/ 的内部文件没有clone下来
解决方案：rm -rf ~/.vim/plugged/YouCompleteMe/third_party/ycmd/third_party/cregex (即删除掉）
再运行git submodule update --init --recursive
然后就可以 ./install.py --clang-completer 成功编译了
5、
然后是问题2：
打开vim，发现YouCompleteme unavailable : no module named future
原因是 ~/.vim/plugged/YouCompleteMe/third_party/python-future/ 的内部文件没有clone下来
解决方案：rm -rf ~/.vim/plugged/YouCompleteMe/third_party/python-future/
再运行git submodule update --init --recursive
然后 ./install.py --clang-completer 再编译
6、
然后是问题3：
当你认为终于搞定了高兴的用vim打开.c文件，然后发现
No .ycm_extra_conf.py file detected, so no compile flags are available. Thus no semantic support for C/C++/ObjC/ObjC++. Go READ THE DOCS NOW, DON'T file a bug report.
居然对c和c++不能用！！！
莫方，看英文，是因为找不到.ycm_extra_conf.py 这个文件
所以解决方法上：发现这个文件在 ~/.vim/plugged/YouCompleteMe/third_party/ycmd/examples/ 中，先用命令
mv ~/.vim/plugged/YouCompleteMe/third_party/ycmd/examples/.ycm_extra_conf.py ~/.vim/plugged/YouCompleteMe/third_party/ycmd/cpp/ycm/从而移动该文件到~/.vim/plugged/YouCompleteMe/third_party/ycmd/cpp/ycm/ 中
然后打开 .vimrc 文件，加入
let g:ycm_global_ycm_extra_conf = ‘~/.vim/plugged/YouCompleteMe/third_party/ycmd/cpp/ycm/.ycm_extra_conf.py’然后就大工告成了。
最后附上一个小提示：遇到问题可以查找github的issues，里面有很多dalao的解决方案
=====================================================
- rm -rf YouCompleteMe/third_party/ycmd/third_party/cregex
- git submodule update --init --recursive at the dir of "YouCompleteMe/third_party/ycmd/third_party"
完美解决！
