Answer 1

I searched for a long time but couldn’t find a solution, so I finally deleted it and reinstalled it.
Note here when reinstalling:

    1、提前将site-package里面的文件保存
    2、将d:\python27下所有文件删除
    3、重新安装python，如果安装界面提示的是change、repair、remove,选择repair,完成后，再重新安装执行remove,完成后再重新安装，安装界面应该就是正常的安装步骤了
    4、安装wxpython 一般是这个文件名 wxPython2.8-win32-unicode-2.8.12.1-py27.exe
    4、将之前的site-packages里的文件覆盖到对应文件夹下
    5、重新安装robotframework robotframework-ride ,如果提示已安装，使用命令 pip uninstall xx卸载后，重新安装。
    6、最后cmd中 d:python27\scripts\python ride.py
    It's done
    附带文件目录：
    robotframework-ride (1.5.2.1)
    robotframework-sshlibrary (2.1.2)
    wxPython2.8-win32-unicode-2.8.12.1-py27.exe
    python2.7.11
