下载pypy
https://bitbucket.org/pypy/pypy/downloads/pypy2-v5.3.0-win32.zip
还需要安装pip
还得装个vc for python
http://aka.ms/vcpython27
安装wxpython
pip.exe install –upgrade –trusted-host wxpython.org –pre -f http://wxpython.org/Phoenix/snapshot-builds/ wxPython_Phoenix
额，安装wxpython失败，原因不明，安装版也不行，提示没有找到_core_模块
不知道是不是和本机的python有冲突
