centos7上自带python2.7，我们需要优化一下python环境。
一、使用豆瓣源加速软件安装
pip install -i flask #使用-i 选项 mkdir ~./pip && vim pip.conf #修改pip的配置文件 [global] index-url = https://pypi.douban.com/simple/
二、修改.vimrc文件
主要增加一些配置选项，例如显示行号，一键执行等
vim .vimrc
set nocompatible "关闭与vi的兼容模式 set number "显示行号 set nowrap "不自动折行 set showmatch "显示匹配的括号 set scrolloff=3 "距离顶部和底部3行" set encoding=utf-8 "编码 set fenc=utf-8 "编码 set mouse=a "启用鼠标 set hlsearch "搜索高亮 syntax on "语法高亮 au BufNewFile,BufRead *.py \ set tabstop=4 "tab宽度 \ set softtabstop=4 \ set shiftwidth=4 \ set textwidth=79 "行最大宽度 \ set expandtab "tab替换为空格键 \ set autoindent "自动缩进 \ set fileformat=unix "保存文件格式 set foldmethod=indent set foldlevel=99 map <F8> :call RunPython()<CR> func! RunPython() exec "W" if &filetype == 'python' exec "!time python2.7 %" endif endfunc
一键F8执行效果
三、配置vim插件管理vundle
Vundle 是 Vim bundle 的简称,使用git来管理vim插件，有了它，安装其它插件就方便很多。
创建目录
cd ~ mkdir .vim cd .vim mkdir bundle
进入目录，下载文件
git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
然后将下列配置放在.vimrc文件的开头：
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() " let Vundle manage Vundle, required Plugin 'VundleVim/Vundle.vim' " All of your Plugins must be added before the following line call vundle#end() " required filetype plugin indent on " required
如果想下载某个插件，比如自动缩进indentpython.vim插件，需要将
Plugin 'vim-scripts/indentpython.vim'
置于call vundle#begin()和call vundle#end()之间，保存配置后在vim中执行
:PluginInstall
四、多窗口编辑
五、安装常用python插件
编程提示插件jedi-vim
pip install jedi git clone --recursive https://github.com/davidhalter/jedi-vim.git ~/.vim/bundle/jedi-vim
2.语法检查syntastic
git clone https://github.com/vim-syntastic/syntastic.git Plugin 'vim-syntastic/syntastic' #.vimrc中增加
3.flak8代码风格检查
pip install flake8 https://github.com/nvie/vim-flake8.git Plugin 'nvie/vim-flake8' #.vimrc中添加
按F7进行检查·
4.添加树形目录
git clone Plugin 'scrooloose/nerdtree' #.vimrc中添加 map <C-n> :NERDTreeToggle<CR> #.vimrc中添加 使用Ctrl+n快捷键
5.缩进显示 indentline
git clone https://github.com/Yggdroot/indentLine Plugin 'Yggdroot/indentLine' #vimrc中添加
6.vim-autopep8自动格式化代码
pip install autopep8 git clone https://github.com/tell-k/vim-autopep8.git Plugin 'tell-k/vim-autopep8' #vimrc中添加 autocmd FileType python noremap <buffer> <F9> :call Autopep8()<CR> #使用快捷键F9
7.auto-pairs自动补全括号和引号
git clone Plugin 'jiangmiao/auto-pairs'
8.ctrlp.vim搜索文件
在vim普通模式下搜索ctl+P即可
Plugin 'kien/ctrlp.vim'
最终，整个配置文件.vimrc如下所示：
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() " let Vundle manage Vundle, required Plugin 'VundleVim/Vundle.vim' Plugin 'davidhalter/jedi-vim' Plugin 'vim-syntastic/syntastic' Plugin 'nvie/vim-flake8' Plugin 'scrooloose/nerdtree' Plugin 'Yggdroot/indentLine' Plugin 'tell-k/vim-autopep8' Plugin 'vim-scripts/indentpython.vim' Plugin 'kien/ctrlp.vim' Plugin 'jiangmiao/auto-pairs' " All of your Plugins must be added before the following line call vundle#end() " required filetype plugin indent on " required set nocompatible "关闭与vi的兼容模式 set number "显示行号 set nowrap "不自动折行 set showmatch "显示匹配的括号 set scrolloff=3 "距离顶部和底部3行" set encoding=utf-8 "编码 set fenc=utf-8 "编码 set mouse=a "启用鼠标 set hlsearch "搜索高亮 syntax on "语法高亮 au BufNewFile,BufRead *.py \ set tabstop=2 "tab宽度 \ set softtabstop=4 \ set shiftwidth=4 \ set textwidth=79 "行最大宽度 \ set expandtab "tab替换为空格键 \ set autoindent "自动缩进 \ set fileformat=unix "保存文件格式 set foldmethod=indent set foldlevel=50 map <F8> :call RunPython()<CR> func! RunPython() exec "W" if &filetype == 'python' exec "!time python2.7 %" endif endfunc map <C-n> :NERDTreeToggle<CR> autocmd FileType python noremap <buffer> <F9> :call Autopep8()<CR>
