在 Windows 10 上安装 django 时出现 python 错误？

Question

使用以下命令安装 django 时，我似乎遇到了错误。我完全按照我正在使用的书的说明进行操作，但出现错误。首先安装 pipenv 给了我关于路径的错误，然后手动更新 windows 中的路径修复了这个问题。

pip3 install pipenv            <---- executes correlty with no errors

pipenv install django ~=3.1.0   <----- get the following errors below

任何帮助将不胜感激。我已经禁用了 Windows Defender，只是将它包含在 Internet 访问问题上，即使错误没有这样报告。我以管理员身份通过windwos power shell运行所有命令。我正在使用 python 3.9

我似乎无法在网上找到有类似问题的人。希望得到一些帮助

谢谢

创建新环境

Mkvirtualenv test
pip install django

Answer 2

只要有人对我遇到上述错误的原因感兴趣，这是因为 django 和 ~ 之间的空格。

pipenv install django ~=3.1.0

pipenv install django~=3.1.0
