我有父进程调用它的子进程。我已将import pdb; pdb.set_trace()
放入子流程代码中。
当我使用python -m pdb parent.py
启动父级时,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
时,它会退出代码。
看起来pdb有效,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
现在停止响应。
根据我在中断后得到的踪迹,它在pdb.set_trace()
电话之后就站在了线上。

答案 0 :(得分:3)
实际上问题是我的代码是将sys.stdout
重定向到日志文件
