hello please help how to install the python virtual environment management pack
and how to create an environment

otherwise the code is vilazit:

C: \ Users \ Admin & gt; pipenv –python 3.9
“pipenv” is not internal or external
command, executable program, or batch file.

Answer 1, authority 100%

First, install pipenv using pip

pip install pipenv

After installation, I create a folder for the virtual environment for the example ‘text’ and go into it, after these actions I specify the version of the interpreter:

pipenv --python 3.9

The command will automatically create a virtual environment and then you can activate the virtual environment:

pipenv shell
