Mac安装robotframework遇到的坑：wxpython
1、安装robot framework
sudo python -m pip install robotframework
这里的python换成本地python的路径：
终端输入命令：python2.7 which
/System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can’t open file ‘which’: [Errno 2] No such file or directory
终端输入：sudo /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python -m pip install robotframework
结果：Successfully installed robotframework-3.1.1
2、安装robotframework-ride
命令：sudo /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python -m pip install robotframework-ride
报错：Could not find a version that satisfies the requirement Pywin32 (from robotframework-ride) (from versions: )
No matching distribution found for Pywin32 (from robotframework-ride)
更换命令：sudo /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python -m easy_install robotframework-ride
结果：Finished processing dependencies for robotframework-ride
3、检查安装是否成功
python -m pip list
sudo /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python -m pip list
4、安装wxpython
安装brew(已安装可忽略)
/usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”
brew install wxpython
5、执行： /usr/local/bin/ride.py
报错：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/
搞了很久，试着修改robotide里_init_.py里的值，不行。最后按提示的下载链接下载后配置好了。
解决wxpython方法：
6、去http://sourceforge.net/projects/wxpython/files/wxPython/下载，我下载的是wxPython3.0-osx-3.0.2.0-cocoa-py2.7.dmg，下载完成后双击打开dmg文件，然后右击pkg文件，选择"显示包内容"
7、打开Contents/Resources/ ，将postflight文件复制到桌面，双击解压wxPython3.0-osx-3.0.2.0-cocoa-py2.7.pax.gz，解压后会生成usr文件夹
8、将usr中的 local/lib 拷贝到usr/local 目录下，若提示已存在lib文件夹，可以选择合并。然后运行之前拷贝到桌面上的 postflight
9、切换到post flight所在的目录，运行命令：sudo ./postflight，结果会看到打印很多Listing /usr/local/lib/wxPython-3.0.2.0/lib/python2.7/site-packages/wx-3.0-osx_cocoa …
10、最后运行ride.py：/usr/local/bin/ride.py
最后打开ride成功啦！
