Django无法导入任何包:AttributeError:__name__ [英] Django fails to import any package : AttributeError: __name__

问题描述

由于某些原因，我不得不在桌面上重新安装Python.从那时起，我的django应用程序无法正常工作.我可以创建一个，但是一旦我在应用程序中的任何位置导入了一个包，就无法运行 python manage.py runserver

For some reasons, I had to reinstall Python on my desktop. Since then, my django applications are not working. I can create one, but as soon as I import a package anywhere in the application, I can't run python manage.py runserver

我可以运行另一个python脚本，可以启动Jupyter Notebooks(并在其中导入完全相同的软件包).我还尝试使用安装的新" python创建新项目，一旦添加 import pandas (或django以外的任何其他软件包)，我就会收到错误消息.

I can run another python script, I can start Jupyter Notebooks (and import the exact same packages in them). I also tried to create new projects with the "new" python installed, as soon as I add import pandas (or any other packages except django), I have the error.

错误消息很长:

推荐答案

中止IDE重构后，请解决此烦人的错误.

Got this annoying error after aborting an IDE-refactoring.

我建议通过以下方法重现该问题:

I suggest the following to reproduce the problem:

• 还原git更改.
• 确保代码中没有循环导入.
• 重新安装虚拟环境.

不幸的是，在我的情况下错误仍然存​​在.所以我知道问题一定出在python上.确实:

Unfortunately the error was still there in my case. So I knew the problem must be with python. And indeed:

• 重新安装python 3.7解决了该问题.
