当我为我的django_test项目执行Python manage.py runserver命令命令我得到以下错误：

我以前从来没有过这样的问题，我的代码一直工作得很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，它工作正常，但系统崩溃，这是我第一次尝试在新机器上运行代码。我使用virtualenv，所以我期望一切顺利，但它不会...

它是一个Python本身的问题？

它看起来像你在新的笔记本电脑上运行的系统版本的Python，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上的virtualenv上的Python版本以及python --version上的新笔记本电脑来查看此版本 - 我曾经在此案例中看到过此错误发生在人们面前。

最好的办法是在新的笔记本电脑上创建一个新的virtualenv，然后重新安装你的软件包（希望你有方便的requirements.txt）。如果您需要在新笔记本电脑上使用相同版本的Python，则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virtualenv指向安装。祝你好运。
