问题一：
命令行启动Appium后，执行测试用例，报错
File "C:UsersluoliangAppDataLocalProgramsPythonPython36-32libsite-packagesseleniumwebdriver emotewebdriver.py", line 154, in __init__
self.start_session(desired_capabilities, browser_profile)
File "C:UsersluoliangAppDataLocalProgramsPythonPython36-32libsite-packagesseleniumwebdriver emotewebdriver.py", line 243, in start_session
response = self.execute(Command.NEW_SESSION, parameters)
File "C:UsersluoliangAppDataLocalProgramsPythonPython36-32libsite-packagesseleniumwebdriver emotewebdriver.py", line 312, in execute
self.error_handler.check_response(response)
File "C:UsersluoliangAppDataLocalProgramsPythonPython36-32libsite-packagesseleniumwebdriver emoteerrorhandler.py", line 130, in check_response
status = value["status"]
KeyError: 'status'
具体原因还未查明，当前处理方式：
重新安装appium版本 cnpm install -g appium
问题二：appium-doctor执行报错
