您正在尝试混合两个世界. Flask(通过其下面的Werkzeug)基于无头运行的假设进行了一些I/O重写.当您在Mac上违反该假设时，您所看到的可能是什么样子.

You're trying to mix two worlds. Flask (via Werkzeug underneath it) does some I/O-rewiring based on the assumption of running headless. It's possible that what you're seeing is what what looks like when you violate that assumption on a Mac.
