Final answer:
To install a different Python version in a venv, ensure the version is installed, create a new venv using the path to the desired Python executable, activate the venv, and use pip to install packages isolated to that environment.
Step-by-step explanation:
To install a different version of Python in a virtual environment (venv), make sure the desired version of Python is already installed on your system. A general instructions for installing a different Python version in a virtual environment may be found here:
If the required Python version is not already installed on your machine, install it. It is available for download from the Python website.
By supplying the location of the Python executable, you can create a new virtual environment. As an example:
If Python 3.8 is installed and python3.8 is the command to execute it, the command python3.8 -m venv /path/to/new/virtual/environment will establish a new venv with Python 3.8.
On Unix/Linux or macOS, use the source command to activate the virtual environment, or ScriptsActivate on Windows. After activation, you should
Note that if you are using a version management tool such as pyenv, you can easily switch between different Python versions and create virtual environments with specific versions without manually specifying the path to the executable.
