调试器在 PyCharm 中突然不起作用

Question

我正在使用：

PyCharm 2016.1.4 Build #PY-145.1504, built on May 25, 2016 JRE:
1.8.0_76-release-b198 x86_64 JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o

在 Mac 上：

OSX El Capitan
Version 10.11.4

在没有对我的代码进行任何更改的情况下，我无法再启动调试器。我仍然可以毫无问题地使用 Run。

如果我只是从终端运行它，调试器也不起作用：

/Users/Vandborg/.virtualenvs/hungry/bin/python /Applications/PyCharm.app/Contents/helpers/pydev/pydevd.py --multiproc --qt-support --client 127.0.0.1 --port 54596 --file /Users/Vandborg/dev/dowant/dowant/manage.py runserver

它会抛出一个未处理的异常，可以在这里看到：

/Users/Vandborg/.virtualenvs/hungry/bin/python /Applications/PyCharm.app/Contents/helpers/pydev/pydevd.py --multiproc --qt-support --client 127.0.0.1 --port 54596 --file /Users/Vandborg/dev/dowant/dowant/manage.py runserver

dowant.templatetags.localization 中的代码已经好几年没有人碰过了。而且它能够运行，当我尝试将它与调试器一起使用时它只是这样做。

Answer 1

无视。我发现了问题，调试和运行加载的顺序内容存在差异，因此无法解决 helper_evalifnotquoted。
