尝试创建虚拟环境时出现 pipenv FileNotFoundError

Question

我正在尝试使用 pipenv 和 Python 3.8.5 设置虚拟环境。 我安装了 Miniconda3 并使用了 pip install --user pipenv 并且看起来安装正常。 运行pipenv --version工作正常。

但是，当尝试使用pipenv --three创建虚拟环境时，结果是：

$ pipenv --three
Creating a virtualenv for this project...
Pipfile: C:\Users\Eamon\python_practice\pipenv-project1\Pipfile
Using C:/Users/Eamon/miniconda3/python.exe (3.8.5) to create virtualenv...

Failed creating virtual environment

[pipenv.exceptions.VirtualenvCreationException]:
Failed to create virtual environment.

我尝试将路径'c:\\users\\eamon\\miniconda3\\Lib\\venv\\scripts\\nt\\python.exe'添加到我的环境变量路径列表中，但这似乎不起作用。 我还可以做些什么？

尝试使用 pip package virtualenv 。 我已经在 Ubuntu 20LTS 和 Windows 10 上试过了，这对我有用。

安装一个 python 虚拟环境构建器：

python3 -m pip install virtualenv

在项目目录中创建一个名为venv的虚拟环境： virtualenv venv

要激活此环境，请在项目目录中使用此命令： source venv/bin/activate

安装 requirements.txt 中列出的 python 模块依赖项：

python3 -m pip install -r requirements.txt

当您在该目录中使用 python 进行 package 安装和在项目目录中运行命令时，您应该激活虚拟环境。 当您需要停用虚拟环境时，请使用deactivate命令执行此操作。

要停用环境，只需运行： deactivate
