各位大神请帮忙看看，我的安卓机在 mac 上能跑起来，到 Windows 上就开始报错!

我用 node 装的 appium
C:\Users\XXX>appium
[Appium] Welcome to Appium v1.7.1
[Appium] Appium REST http interface listener started on 0.0.0.0:4723

错误截图：

源码如下
def appium_start(device, OS):
# Start appium server
if OS == 'Mac':
os.system('node /Application/Appium.app/Content/Resource/app/node_modules/appium/build/lib/main.js &')
sleep(5)
elif OS == 'Windows':
os.system('start /b appium')
sleep(5)
else:
print "Appium server failed to start, please check OS!"
