折腾：

最后发现：
原来是写错了：
socketio.run() |
应该写成是：
from runningfast.app import app, socketio if __name__ == ‘__main__’: #app.run(debug=True) # app.run() socketio.run(app) |
然后就可以正常启动了：

【总结】
此处是：
新增了Websocket后，代码笔误为：
from runningfast.app import socketio if __name__ == ‘__main__’: socketio.run() |
改为：
from runningfast.app import app, socketio if __name__ == ‘__main__’: socketio.run(app) |
即可正常运行了。
