打包pybot，方便robot用例迁移而不依赖robot环境

查看bin目录下的pybot，发现是python脚本

于是想到了将脚本打包，到时候直接运行

#!/usr/local/bin/python3.7

import sys
from robot import run_cli

run_cli(sys.argv[1:])

　　使用pyinstaller打包之后，./pybot发现执行用例会报错：

[ ERROR ] Importing test library 'robot.libraries.BuiltIn' failed: Module 'robot.libraries' does not contain 'BuiltIn'.

　　想到了pyinstaller打包并不会将隐藏引用的包打进来，

需要修改pybots.spec文件，将文件设置为:

hiddenimports=['robot.libraries.BuiltIn','robot.libraries.Reserved','robot.libraries.Collections','robot.libraries.Easter','robot.libraries.OperatingSystem','robot.libraries.DateTime','robot.libraries.Dialogs','robot.libraries.Process','robot.libraries.Remote','robot.libraries.Screenshot','robot.libraries.String','robot.libraries.Telnet','robot.libraries.XML'],

　　最后pyinstaller pybot.spec即可
