尝试创建虚拟环境时 pipenv FileNotFoundError

Question

我正在尝试使用带有 Python 3.8.5 的 pipenv 设置虚拟环境。我安装了 Miniconda3 并使用了 pip install --user pipenv ，它似乎安装得很好。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。我还能做什么？

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

安装python虚拟环境生成器：

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

当您在此目录中使用 python 进行软件包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。

要停用环境，只需运行：deactivate
