flask 网页端报错但是运行不报错

123...

为什么现在仅在网页界面报错
现在用print就会报错OSError: [Errno 22] Invalid argument
The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.
To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.

You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:

dump() shows all variables in the frame
dump(obj) dumps all that's known about the object

好像是以为我把gitee上的这个代码又重新拉个一个地方后，出现的这个问题
