python - Django "__init__() keywords must be strings"运行时出错 "runserver"

Question

我刚刚设置了 virtualenv 来启动 django 项目。我安装一切正常。当我发出“python manage.py runserver”时，它吐出这个错误。我尝试了所有类型的 django runserver 错误，但似乎没有人遇到过这个问题。有没有人对此有深入的了解？

是a known issue . Django 1.5 requires Python 2.6.5 或更新版本。您的计算机上安装了旧版本的 Python。你需要 install a newer version of Python ，例如 Python 2.7.x。
