Ubuntu 16.04.04-desktop 中VIM安装YouCompleteMe插件

从了解YCM以来陆陆续续安装过两次了，都是出现各种问题，因为太费时间就没有安装；由于最近需要经常在Linux下写代码，所以在昨天又尝试安装了一次，终于安装成功了；这一次首先是用 full install guide，后来一直出错就回到用脚本安装，通过full install guide也更加了解了YCM的安装。在这里记录一下安装的详细过程，以备后续再次安装可以查阅。

安装环境：宿主机-Win7  VMware虚拟机-Ubuntu 16.04.04-desktop

安装步骤主要分为：①更新VIM版本到8.x ②安装Vundle ③在Vundle中安装YouCompleteMe插件 ④安装依赖并编译YCM ⑤配置.vimrc和.ycm_extra_conf.py文件。

首先进入YCM的官网，选择相应OS，查看相关安装步骤，网站地址如下：

https://valloric.github.io/YouCompleteMe/#ubuntu-linux-x64

 

一、 更新VIM到8.x

  由于YCM要求VIM版本至少要 Vim 7.4.1578以上，我们这里直接上VIIM8。

1、 进入Compile VIM From Source的github页面，查看说明。

2、安装依赖库，这里可能会提示有些库没有安装成功，只要sudo apt-get update更新一下再执行就好了。

sudo apt install -y libncurses5-dev libgnome2-dev libgnomeui-dev \
libgtk2.0-dev libatk1.0-dev libbonoboui2-dev \
libcairo2-dev libx11-dev libxpm-dev libxt-dev python-dev \
python3-dev ruby-dev lua5.1 liblua5.1-dev libperl-dev git

3、移除原来老版本的VIM

sudo apt remove vim vim-runtime gvim

4、下载VIM源码

git clone https://github.com/vim/vim.git

5、进入源码编译

注意原文中这句：这里比较坑

Note for Ubuntu users: You can only use Python 2 or Python 3. If you try to compile vim with both python-config-dir and python3-config-dir, YouCompleteMe will give you an error YouCompleteMe unavailable: requires Vim compiled with Python (2.6+ or 3.3+) support, when you start VIM.

然后更改下面的的命令，把原说明中的关于python3的两行去掉，如下：

cd vim
./configure --with-features=huge \
							--enable-multibyte \
							--enable-rubyinterp=yes \
							--enable-pythoninterp=yes \
							--with-python-config-dir=/usr/lib/python2.7/config \

							--enable-perlinterp=yes \
							--enable-luainterp=yes \
							--enable-gui=gtk2 \
							--enable-cscope \
							--prefix=/usr/local
make VIMRUNTIMEDIR=/usr/local/share/vim/vim80

6、make安装

cd ~/vim
sudo make install

7、把VIM设置成默认的编辑器

sudo update-alternatives --install /usr/bin/editor editor /usr/local/bin/vim 1
sudo update-alternatives --set editor /usr/local/bin/vim
sudo update-alternatives --install /usr/bin/vi vi /usr/local/bin/vim 1
sudo update-alternatives --set vi /usr/local/bin/vim

8、测试VIM版本是否有升级到8.x，执行下面命令后如果显示VIM8.x则表示成功

vim --version

成功显示如下：

9、查看VIM是否支持Python（？是不是这么说），在full install guide有如下这句话，这里测试一下。

After you have made sure that you have Vim 7.4.1578+, type the following in Vim: :echo has('python') || has('python3'). The output should be 1. If it's 0, then get a version of Vim with Python support.

命令：

vim
：echo has('python') || has('python3')

如果你在第5步直接用那个网页上面说的命令执行，这里会输出0；进一步会导致后面出错。

 

 

二、安装Vundle

1、Vundle是一个VIM插件管理器，YCM官方推荐用Vundle来管理插件，我们就按官方的来

2、Vundle的github页面有相关安装步骤，按这个来就好，页面地址如下：

https://github.com/VundleVim/Vundle.vim#about

3、获取Vundle

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

4、在~/目录创建.vimrc（注意是隐藏文件） ，并设置，设置内容如下（上面页面上有讲的哦），注意前后空格比较多的那行，要额外添加那行才会安装YCM插件。

set nocompatible              " be iMproved, required
filetype off                  " required

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" alternatively, pass a path where Vundle should install plugins
"call vundle#begin('~/some/path/here')

" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'

" The following are examples of different formats supported.
" Keep Plugin commands between vundle#begin/end.
" plugin on GitHub repo
Plugin 'tpope/vim-fugitive'
" plugin from http://vim-scripts.org/vim/scripts.html
" Plugin 'L9'
" Git plugin not hosted on GitHub
Plugin 'git://git.wincent.com/command-t.git'
" git repos on your local machine (i.e. when working on your own plugin)
Plugin 'file:///home/gmarik/path/to/plugin'
" The sparkup vim script is in a subdirectory of this repo called vim.
" Pass the path to set the runtimepath properly.
Plugin 'rstacruz/sparkup', {'rtp': 'vim/'}
" Install L9 and avoid a Naming conflict if you've already installed a
" different version somewhere else.
" Plugin 'ascenator/L9', {'name': 'newL9'}



Plugin 'Valloric/YouCompleteMe'




" All of your Plugins must be added before the following line
call vundle#end()            " required
filetype plugin indent on    " required
" To ignore plugin indent changes, instead use:
"filetype plugin on
"
" Brief help
" :PluginList       - lists configured plugins
" :PluginInstall    - installs plugins; append `!` to update or just :PluginUpdate
" :PluginSearch foo - searches for foo; append `!` to refresh local cache
" :PluginClean      - confirms removal of unused plugins; append `!` to auto-approve removal
"
" see :h vundle for more details or wiki for FAQ
" Put your non-Plugin stuff after this line

5、进入VIM，并输入下面命令开始安装插件。如何在VIM中执行命令：命令行输入vim进入vim——>输入：号——>输入命令，按回车键！

:Plugin 'Valloric/YouCompleteMe'

6、安装完成是最下方会有提示：

The ycmd server SHUT DOWN (restart with ':YcmRestartServer'). YCM core library not detected; you need to compile YCM before using it. Follow the instructions in the documentation.

由于YCM还没有安装好，先不管这个。

 

三、其他依赖安装及YCM编译

1、安装cmake

sudo apt-get install build-essential cmake

2、安装Python库相关

sudo apt-get install python-dev python3-dev

3、编译YCM（Compiling YCM with semantic support for C-family languages），这里可能比价慢，我等了大概十几分钟。

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

4、如果前一步没有报错的话就算安装成功了。下面就是配置.vimrc和.ycm_extra_conf.py。细心的可能会发现编译过程中有这个提示

NOT using clang-tidy for static analysis

通过查google了解到好像并不会有影响：

https://github.com/Valloric/YouCompleteMe/issues/3048

@52101107 YCM doesn't depend on clang-tidy. If you're talking about the cmake output then this is totally unrelated to the original issue and, second, you can just ignore that.

 

安装成功后命令行输出：

 

四、配置.ycm_extra_conf.py及.vimrc

1、在.vimrc中加入以下两行

let g:ycm_global_ycm_extra_conf='~/.vim/bundle/YouCompleteMe/third_party/ycmd/examples'
let g:ycm_server_python_interpreter='/usr/lib/python2.7'

我的.vimrc配置

set nocompatible              " be iMproved, required
filetype off                  " required

"set the runtime path to include Vundle and initialize

set rtp+=~/.vim/bundle/Vundle.vim

call vundle#begin()

" alternatively, pass a path where Vundle should install plugins

"call vundle#begin('~/some/path/here')



" let Vundle manage Vundle, required

PS： 如果要在vim中让YCM识别你指定的头文件的内容，在~/.vim目录中的.ycm_extra_conf.py文件中（或者这个文件在别的目录也OK），加入：

'/home/ct/workspace/muduo',
'-isystem',

内容。
