django 和 python manage.py runserver 执行错误

Question

当我为 django_test 项目执行 python manage.py runserver 命令时，出现以下错误：

我以前从未遇到过这个问题，我的代码一直运行良好，直到我将项目从一台笔记本电脑移到另一台笔记本电脑并且无法在此处执行。

原来，它运行良好，但系统崩溃了，这是我第一次尝试在新机器上运行代码。 我使用 virtualenv 所以我希望一切顺利，但它并没有......

是python本身的问题吗？

看起来您在新笔记本电脑上运行的是 python 的系统版本，而不是 virtualenv，所以它可能是一个不同的版本。 您可以通过查看旧笔记本电脑中的 virtualenv 上的 Python 版本和使用python --version的新笔记本电脑来检查这一点 - 我以前见过这种错误发生在这种情况下。

最好的办法是在新的笔记本电脑上创建一个新的 virtualenv，然后重新安装你的包（希望你有一个 requirements.txt 方便）。 如果您需要在新笔记本电脑上安装相同版本的 Python，您必须探索在新笔记本电脑上安装该版本（不要覆盖系统版本！），并将您的 virtualenv 指向安装。 祝你好运。
