在树莓派python中导入easygui模块

1. 导入easygui
   输入sudo pip install easygui
   如果遇到链接超时，换阿里云的源
   输入sudo pip install easygui -i http://mirrors.aliyun.com/pypi/simple/
   2.使用buttonbox创建一个选择界面并返回选择项
   while True:
   choice = buttonbox(msg = ‘What program you want to run?’,choices = (‘exit’,‘voive_control’,‘talking’))
   if choice == ‘exit’:
   stop_Grbl()#stop Grbl
   thread1.close()
   elif choice == ‘voive_control’:#run voive_control program

   elif choice == ‘talking’: #run talking program
   stop_Grbl()#stop Grbl
