我正在尝试为Django启动Pinax项目。我设置了我的Python虚拟环境。升级的设置工具。升级了点子。安装了Pinax。然后，当我尝试'pinax启动博客my_site'时，它给出了以下错误：

我已经尝试在我的conda环境中创建一个python虚拟环境。还尝试制作一个独立的python环境。都没有解决它。还尝试使用pip安装django。

发出以下错误：

sudo pip install django

你会建议什么？谢谢你的阅读！

答案

看起来你正在使用python 2;如果这是正确的Django版本2只支持python 3.请参考https://docs.djangoproject.com/en/2.0/releases/2.0/#python-compatibility

您可以尝试安装较低版本的Django：

pip install "Django<2"

另一答案

你可以尝试：

pip3 install django
