创建与Windows上安装版本不同的Python虚拟环境

Question

To run some script I need specific version of python (3.7.1) . On my PC I have python 3.7.3

For creating virtual environment I am using:

    python -m venv virtual

Which gives me fully functional python but in version 3.7.3 and I need 3.7.1

How can this be achieved?

Answer 1

virtualenv can only create environments for versions of python installed on the machine.

You may install multiple versions in parallel on windows then select which one to use.

Answer 2

Just install Python 3.7.1. Assuming you are using virtualenv , create your environment as:

virtualenv -p /home/username/opt/python-3.7.1/bin/python Project_Name
