我有父进程调用它的子进程。我放了import pdb; pdb.set_trace()子进程代码。

当我启动父级时，python -m pdb parent.py它会被冻结。调试器不响应我输入的任何命令。但是当我点击quit或continue它确实退出代码时。

看起来 pdb 可以工作，但不会产生任何输出。

$ python -m pdb parent.py
n -m pdb parent.py
> d:\scripts\parent.py(53)<module>()
-> '''
(Pdb) c

它现在停止响应。

pdb.set_trace()根据我打断后得到的痕迹，它在通话后就站在线路上。

实际上问题是我的代码正在重定向sys.stdout到日志文件
