生信之旅

我使用的是debian9，默认安装了Python3.5，但是没有安装vim，所以我使用了APT来安装vim：

sudo apt-get install vim-nox

该版本的vim默认支持Python3，所以不用通过源码编译的方法进行配置。

要查看vim是否支持Python3，可以使用命令：

vim --version

来查看，如果Python3前面有个+号则表示支持。

接下来给vim装一个插件管理器vundle:

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

然后在个人的主目录下的.vimrc文件（找不到就自己创建）中加上：

set nocompatible              
filetype off                  
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" alternatively, pass a path where Vundle should install plugins
"call vundle#begin('~/some/path/here')
Plugin 'VundleVim/Vundle.vim'

" All of your Plugins must be added before the following line
call vundle#end()            
filetype plugin indent on

下一步，安装各种插件，在.vimrc文件中添加下列信息到vundle管理安装插件的行中

" 添加nerdtree插件
 Plugin 'scrooloose/nerdtree'

"代码自动补全插件
 Plugin 'Valloric/YouCompleteMe'

"python语法检测
 Plugin 'scrooloose/syntastic'

"添加PEP8代码风格检查
 Plugin 'nvie/vim-flake8'

"代码折叠插件
 Plugin 'tmhedberg/SimpylFold'

"自动缩进
 Plugin 'vim-scripts/indentpython.vim'

"Powerline状态栏
 Plugin 'Lokaltog/powerline', {'rtp': 'powerline/bindings/vim/'}

"在vim的normal模式下搜索文件
 Plugin 'kien/ctrlp.vim'

"快速注释/解开注释
 Plugin 'scrooloose/nerdcommenter'

保存后，在终端中中输入vim进入vim编辑器，然后输入
:PluginInstall

进行安装。

安装完成后（YouCompleteMe的安装时间较长）还需要到YouCompleteMe所在目录下运行

python3 install.py --clang-completer

再进行相应的设置，我的.vimrc文件如下，可供参考：

set nu
set encoding=utf-8
" vundle设置
set nocompatible " be iMproved, required
filetype off " required

set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()

" 添加nerdtree插件
