如何在Mac os x 10.12.3上安装 robotframework，最近折腾了几天也没搞定。网上该找的文档也基本看了遍未能解决，特来请教。
相关依赖已经通过 pip 安装上了。
pip freeze
robotframework==3.0.2
robotframework-ride==1.5.2.1
wxPython-common==2.8.12.1

执行 ride.py 还是提示未找到 wxPython，但单独进 python 里面 import wx 也是正常的：

python
Python 2.7.10 (default, Jul 30 2016, 19:40:32) 
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.34)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import wx
>>> wx
<module 'wx' from '/usr/local/lib/wxPython-unicode-2.8.12.1/lib/python2.7/site-packages/wx-2.8-mac-unicode/wx/__init__.pyc'>
>>> 

ride.py 
wxPython not found.
You need to install wxPython 2.8.12.1 or 3.0.2 or newer with unicode support to run RIDE. wxPython can be downloaded from http://sourceforge.net/projects/wxpython/files/wxPython/

单独执行 pybot --help，也报错，去 python 命令行里执行这个 import 确实不行:

Traceback (most recent call last):
  File "/usr/local/bin/pybot", line 4, in <module>
    from robot import run_cli
ImportError: cannot import name run_cli

虽然 Mac 自带的 python 是 64bit 的，但我已经调整过了参数了：
defaults write com.apple.versioner.python Prefer-32-Bit -bool yes

>>> import struct;print struct.calcsize("P") * 8
32

快要绝望了，求大神指点下。不吝辞谢...
