vim 安裝插件

1 簡介

• 插件介紹：YouCompleteMe是一款針對Vim的快速，即用型的模糊搜索代碼補全引擎。包括以下幾種引擎：
  • 基於標識符的引擎，可與每種編程語言一起使用
  • 基於Clang的引擎，為C / C ++ / Objective-C / Objective-C ++（C系列）提供本地語義代碼補全
  • 基於Jedi的Python 2和3的補全引擎
  • 基於OmniSharp的C＃補全引擎
  • Go的Gocode和Godef語義引擎的組合，
  • 基於TSServer的TypeScript完成引擎，
  • 基於Tern的JavaScript補全引擎，
  • 基於racer的Rust補全引擎，
  • 基於jdt.ls的Java實驗性補全引擎。
  • 基於omnifunc的補全引擎，它使用來自Vim的omnicomplete系統的數據為許多其他語言（Ruby，PHP等）提供語義補全。
  • 基於UltiSnips的代碼片補全引擎

     入坑vim多天后逐步裝插件對vim進行完善，終於今天開始嘗試裝最牛插件之一YouCompleteMe。一路也是遇到不少問題，甚至想從源碼編譯，最后發現其實都是些小問題。

本系統為ubuntu

先上插件網址：https://github.com/Valloric/YouCompleteMe

1、

請確保有以下依賴

sudo apt install build-essential cmake python3-dev

2、

這里用的是 vim-plug 下載，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()

然后漫長等待至下好，這個時候並不是結束，而是才剛剛開始

3、

cd ~/.vim/plugged/YouCompleteMe/              (就是找到安裝目錄）

一般這個時候都沒有完整克隆下來的，執行命令

git submodule update --init --recursive

好像就可以完整安裝下來

4、本文章的重點之一，就是這里開始遇到問題的

在YouCompleteMe目錄下運行編譯安裝

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

然后就驚奇發現終端有如下回復

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.

其實這是因為 ~/.vim/plugged/YouCompleteMe/third_party/ycmd/third_party/cregex/ 的內部文件沒有clone下來

解決方案：rm -rf ~/.vim/plugged/YouCompleteMe/third_party/ycmd/third_party/cregex    (即刪除掉）

                   再運行git submodule update --init --recursive

然后就可以  ./install.py --clang-completer  成功編譯了

5、

然后是問題2：

打開vim，發現YouCompleteme unavailable : no module named future

原因是 ~/.vim/plugged/YouCompleteMe/third_party/python-future/ 的內部文件沒有clone下來

解決方案：rm -rf ~/.vim/plugged/YouCompleteMe/third_party/python-future/

                   再運行git submodule update --init --recursive

                   然后  ./install.py --clang-completer  再編譯

6、

然后是問題3：

當你認為終於搞定了高興的用vim打開.c文件，然后發現

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.

居然對c和c++不能用！！！

莫方，看英文，是因為找不到.ycm_extra_conf.py 這個文件

所以解決方法上：發現這個文件在   ~/.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/

從而移動該文件到~/.vim/plugged/YouCompleteMe/third_party/ycmd/cpp/ycm/ 中

然后打開  .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。

 

最后附上一個小提示：遇到問題可以查找github的issues，里面有很多dalao的解決方案

 

=====================================================

•  rm -rf YouCompleteMe/third_party/ycmd/third_party/cregex 
•  git submodule update --init --recursive  at the dir of "YouCompleteMe/third_party/ycmd/third_party"

完美解決！

 注意：補全c++頭文件，或者c的頭文件，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',
