Django和Python的manage.py runserver命令執行錯誤

Question

當我爲我的django_test項目執行Python manage.py runserver命令命令我得到以下錯誤：

我以前從來沒有過這樣的問題，我的代碼一直工作得很好直到我將項目從一臺筆記本電腦移到另一臺筆記本電腦，並且無法在此處執行。

原來，它工作正常，但系統崩潰，這是我第一次嘗試在新機器上運行代碼。我使用virtualenv，所以我期望一切順利，但它不會...

它是一個Python本身的問題？

它看起來像你在新的筆記本電腦上運行的系統版本的Python，而不是virtualenv，所以它可能是一個不同的版本。您可以通過查看舊筆記本電腦上的virtualenv上的Python版本以及python --version上的新筆記本電腦來查看此版本 - 我曾經在此案例中看到過此錯誤發生在人們面前。

最好的辦法是在新的筆記本電腦上創建一個新的virtualenv，然後重新安裝你的軟件包（希望你有方便的requirements.txt）。如果您需要在新筆記本電腦上使用相同版本的Python，則必須探索在新筆記本電腦上安裝該版本（不要覆蓋系統版本！），並將virtualenv指向安裝。祝你好運。
