尝试创建虚拟环境时出现pipenv FileNotFoundError

Question

我正在尝试使用Python 3.8.5中的pipenv来设置一个虚拟环境。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运行良好。

然而，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:UsersEamonpython_practicepipenv-project1Pipfile
Using C:/Users/Eamon/miniconda3/python.exe (3.8.5) to create virtualenv...

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上尝试过了，这对我很有效

安装python虚拟环境生成器：

python3 -m pip install virtualenv

在项目目录virtualenv venv中创建一个名为venv的虚拟环境

要激活此环境，请在项目目录中使用以下命令：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进行包安装和在项目目录中运行命令时，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
