我已经在 Pycharm 中设置了 python-django 项目。

在运行模式下的 python manage.py runserver 命令上,它工作正常,但是当我在 Debug模式下运行项目时,出现以下异常:

我还创建了新的 Virtua ENV 和新的虚拟 ENV 也有同样的问题!

数据库设置:

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'db_name',
'USER': 'user',
'PASSWORD': 'passworf',
'HOST': 'localhost',
'PORT': '',
}
}

几天前它工作正常,但是在 Pycharm 的新更新版本之后,我只在一个项目上遇到了这个问题。

最佳答案

这是 PyCharm 2019.2 调试器中某些 Python 版本的回归,例如旧 2.7.x https://youtrack.jetbrains.com/issue/PY-36726

修复已准备就绪,将包含在 2019.2.1 次要更新中,预览版将于本周上线。
