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-dev

2、

这里用的是 vim-plug 下载，用vundle也差不多

1. call plug#begin('~/.vim/plugged')
2. Plug 'Valloric/YouCompleteMe', { 'do': './install.py --clang-completer'}
3. 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

1. cd ~ /.vim/bundle/YouCompleteMe
2. ./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！

 注意：补全c++头文件，或者c的头文件，需要在 .ycm_extra_conf.py 文件里修改 flags

flags = [

] 里面加上，下面

'-isystem',
'/usr/include', '-isystem', '/usr/include/c++/5.4.0',
