无法使用pipenv安装django，尽管已安装并通过命令提示符识别

Question

我一直在尝试使用 pipenv 为 django 设置虚拟环境。 我已经安装了 pipenv 并正确配置了路径。 当我运行以下命令时

pipenv --version

我明白了

pipenv, version 2022.9.8

这意味着 pipenv 正在运行。

但是当我尝试使用以下命令安装 django 时

pipenv install django

我收到以下错误。

C:\Users\Saifia>pipenv install django

我一整天都在尝试解决这个问题并尝试了各种方法，但我是新手，我无法弄清楚我的错误。

任何帮助将不胜感激！

Answer 1

我正在使用 virtualenv 进行虚拟化，并且必须使用 pipenv 来遵循教程并且无法让 pipenv 工作。 我必须卸载 virtualenv 和 pipenv 并重新安装 pipenv 才能工作。 我仍在使用 pipenv，但我不喜欢它 virtualenv 对我来说效果更好。

Answer 2

我认为你的问题的关键是回溯中的最后一条消息：

“ValueError：不是有效的 python 路径：‘C:/Users/Saifia/anaconda3/Scripts/python.exe’”

检查并查看此文件是否存在于此位置。

如果不是，则您的默认版本 python 在 pipenv 中设置不正确。

在安装 pipenv 之前停用任何虚拟环境并检查您的 python 版本。
