在Centos7上部署安装RobotFramework

1. RF框架
   pip install 或 easy_install robotframework
2. wxPython
   建议yum安装方式
   先用yum查看wxPython安装包有哪些： yum list | grep wxPython
   可以看到有2.8.12版本的包，直接yum install安装即可
   sudo yum install wxPython 或 sudo yum install wxPython-2.8.12.0-9.el7.x86_64
   sudo yum install wxPython-devel 或 sudo yum install wxPython-devel-2.8.12.0-9.el7.x86_64
3. RF IDE
   sudo pip install robotframework-ride
4. Third party libraries
   e.g.
   sudo pip install robotframework-selenium2library
   sudo pip install robotframework-databaselibrary
   sudo pip install robotframework-httplibrary
   sudo pip install robotframework-sshlibrary
