macvim下载并搭建mac下的python开发环境

最近准备入门python，于是网上搜索mac下的开发工具，大多数文章推荐使用macvim,下面就给出下载地址和配置。

1.macvim 下载地址：https://github.com/macvim-dev/macvim/releases

2.下载 dmg完成后直接双击安装，将MacVim.app拖进application里面，mvim不用管，启动macvim的时候可能会出现未授权之类的提示，不必忧心，在系统设置->security&privacy->general下选择打开就可以了。至于mvim本来是要拷贝到~/usr/bin 里面的，我没有设置，因为mac os 10.11 没有权限向bin中写文件，所以不能将mvim拷贝到~/usr/bin里面，但是据说可以通过这个方法解决https://segmentfault.com/q/1010000003095378?_ea=301917，但是我没试过。最后弹出桌面上的macvim..

3.于是macvim安装完成，就等着配置python插件了。插件配置比较啰嗦。

网上搜索了很多介绍插件的文章，最后决定用vbundle。参考了一下两个链接

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

总结上述我自己配置了一个文件

我配置的vimrc不是在~/.vimrc里面配置的，而是在 find->application->macvim->右击show package contents->contents->Resources->vim->vimrc,这里面改的，修改后的文件如下

" System vimrc file for MacVim

" Maintainer: Bjorn Winckler <[e-mail]>

" Last Change: Sat Aug 29 2009

set nocompatible

" The default for 'backspace' is very confusing to new users, so change it to a

" more sensible value.  Add "set backspace&" to your ~/.vimrc to reset it.

set backspace+=indent,eol,start

" Disable localized menus for now since only some items are translated (e.g.

" the entire MacVim menu is set up in a nib file which currently only is

" translated to English).

set langmenu=none

set encoding=utf-8 "设置编码"

syntax on       "语法高亮

set number      "显示行号

set tabstop=4    "设置tab为四个空格

set softtabstop=4 "设置软tab为四个空格

set shiftwidth=4

set expandtab

" Enable folding 开启代码折叠

set foldmethod=indent

set foldlevel=99

" Enable folding with the spacebar代码折叠需要手动输入:za，这样设置以后就不用手动输入了，点一下空格就能实现折叠和展开

nnoremap <space> za

“ vbundle设置

" alternatively, pass a path where Vundle should install plugins

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

" let Vundle manage Vundle, required

" The following are examples of different formats supported.

" Keep Plugin commands between vundle#begin/end.

" Plugin 'git://git.wincent.com/command-t.git'

" git repos on your local machine (i.e. when working on your own 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'}

" 通过安装syntastic插件，每次保存文件时Vim都会检查代码的语法：

Plugin 'scrooloose/syntastic'

" 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

多个文件被打开，退出其中一个还是用老方法 esc->:q 

好了就这些了，我还要继续研究如何方便使用。
