Question

我正在尝试学习Django并寻找一种安装方式，它说创建虚拟环境比在全局安装它更好，因此我安装了pipenv很好，但是当我尝试在pipenv中安装Django时给了我这个错误，我在其他任何现有帖子中都找不到答案。

pipenv的安装：

尝试在pipenv中安装Django后出现错误

PS C:\Users\max25\Desktop\Python\learning_frameworks.py> pipenv install django

Answer 1

pipenv不再得到积极开发，也许poetry会更好地满足您的需求。但是，如果您只想使用virtualenv来管理dependencies，我们可以直接使用virtualenv。

$ pip install virtualenv
$ virtualenv django
$ source django/bin/activate
$ pip install django

使用source命令后，如果使用的是Linux，则会显示以下内容：

(django) $

这意味着您在虚拟环境中。

Answer 2

如果您具有Python 3.5或更高版本。创建虚拟环境就像在命令行中运行以下命令一样容易。如果您使用的是Windows，那么我会使用它。

python -m venv name
#replace name with your custom name, or if you want to use name of current directory just use a dot (.)

#activate environment
Scripts/activate
#then use simple pip to install dependencies, if you have a requirement text file.
pip install -r ./requirements.txt
pip install django

Answer 3

我发现我在初次安装Python时并未将Python添加到路径中，所以我不得不重新安装Python（是的，这的确是路径错误）。
