Question

我刚从2.0版升级到Django 2.2.3。

由于某种原因，系统只会在进入新页面时停止工作。我可能会翻一页或一页，然后服务器停止。

我也在使用Cookiecutter。

以下是我收到的典型消息。虽然改变了。

在此之前，我表现得很奇怪-为什么我要升级。

我检查了所有迁移情况。重新安装了Django。使用Pycharm。

谢谢。

AttributeError: cffi library '_ffi' has no function, constant or global variable named '__spec__'

The above exception was the direct cause of the following exception:
