Pycharm 调试器不会在断点处停止 [英] Pycharm debugger does not stop on breakpoints

问题描述

我有一个要调试的 Flask 项目(直到几个小时前它都可以正常工作) - 当我调试项目时，我看到以下内容:

I have a flask project I am trying to debug (this was working absolutely ok till few hours ago) - When I debug the project, I see the following :

Connected to pydev debugger (build 135.1057)
/Users/vantani/cp/bin/python /Applications/PyCharm.app/helpers/pydev/pydevd.py --multiproc --save-  
signatures --client 127.0.0.1 --port 49223 --file /Users/vantani/cp/unnamed/manage.py server
pydev debugger: process 484 is connecting

/Users/vantani/cp/lib/python2.7/site-packages/flask_cache/__init__.py:152: UserWarning: Flask-  
Cache: CACHE_TYPE is set to null, caching is effectively disabled.
warnings.warn("Flask-Cache: CACHE_TYPE is set to null, "
* Running on http://127.0.0.1:5000/
* Restarting with reloader
pydev debugger: process 498 is connecting

正如我所说，此设置运行良好.现在，调试器不会在断点处停止并且调试器窗口是空的.我看到 PyDev 创建了两个进程，我想这是导致此问题的原因.我已经重新启动了我的机器，但只有一个 pycharm 进程在运行.

As I said this setup was working fine. Now, the debugger does not stop at the breakpoint and the debugger window is empty. I see that there are two processes created by PyDev and I guess that is causing this issue. I have restarted my machine and there is only one pycharm process running.

推荐答案

有时这可能是由于其他模块使用相同的跟踪 API (sys.settrace) 作为调试器，例如Coverage.py.解决方案是转到您的 Rub/Debug Configurations 并将 --no-cov 标志添加到 Additional Arguments.

Sometimes this might be caused by the fact that some other module is using the same tracing api (sys.settrace) as debugger, for instance Coverage.py. The solution would be to go to your Rub/Debug Configurations and add --no-cov flag to the Additional Arguments.

或者，您可能希望删除 pytest 设置(即 pytest.ini)中的所有 --cov 或使用 --no-cov标志，即

Alternatively you might want to delete all --cov in pytest settings (i.e. pytest.ini) or run tests with --no-cov flag, i.e.

    pytest test.py --no-cov

这也可能是由错误的文件名引起的，例如您的文件/目录中有特殊字符或空格.尝试删除它们或更改为例如下划线 (_).

It might be also caused by a bad filename, e.g. your file/directory has special characters or spaces in it. Try removing them or changing to e.g. underscore (_).
