Windows环境下python多版本配置方案

系统环境

Windows，安装了msys2，windows和msys2都安装了python，且版本比较多，使用shell/bash聚合工具conemu64

配置方案

配置msys2环境用户目录下的.bashrc，增加alias如下，日常通过conemu64模拟出来的msys2终端工具调用：

# msys2 python 2.7

alias mpy="/usr/bin/python2.exe"

alias mpip="/mingw64/bin/pip2.exe"

alias mei="/mingw64/bin/easy_install-2.7.exe"

# msys2 python 3.4

alias mpy3="/usr/bin/python3.exe"

alias mpip3="/mingw64/bin/pip3.exe"

alias mei3="/mingw64/bin/easy_install-3.5.exe"

# windows python 2.7

alias wpy="/c/Develop/Python27/python.exe"

alias wpip="/c/Develop/Python27/Scripts/pip2.exe"

alias wei="/c/Develop/Python27/Scripts/easy_install-2.7.exe"

alias wip="/c/Develop/Python27/Scripts/ipython.exe"

# pypy 2.7

alias pypy="/c/Develop/pypy/pypy2-v5.6.0-win32/pypy.exe"

alias wpip="/c/Develop/pypy/pypy2-v5.6.0-win32/bin/pip2.7.exe"

alias wei="/c/Develop/pypy/pypy2-v5.6.0-win32/bin/easy_install-2.7.exe"

# windows python 3.4

alias wpy3="/c/Develop/Python34/python.exe"

alias wpip3="/c/Develop/Python34/Scripts/pip3.4.exe"

alias wei3="/c/Develop/Python34/Scripts/easy_install-3.4.exe"

alias wip3="/c/Develop/Python34/Scripts/ipython.exe"

# Anaconda2

alias apy="/C/Develop/Anaconda2/python.exe"

alias apip="/c/Develop/Anaconda2/Scripts/pip.exe"

alias aei="/c/Develop/Anaconda2/Scripts/easy_install.exe"

alias aip="/c/Develop/Anaconda2/Scripts/ipython.exe"

# Anaconda3

alias apy3="/C/Develop/Anaconda3/python.exe"

alias apip3="/c/Develop/Anaconda3/Scripts/pip.exe"

alias aei3="/c/Develop/Anaconda3/Scripts/easy_install.exe"
