How Can I Programmatically Install Python Modules Within My Code?

Installing Python Modules Within Code

In certain situations, it may be necessary to install a Python module directly within your code, instead of using a package manager like pip. This question explores the options available for accomplishing this task.

Recommendation: Calling Pip's Command-Line Interface

Despite various suggestions in this thread, the officially recommended approach is to invoke pip's command-line interface via a subprocess, as illustrated below:

import subprocess
import sys

def install(package):
    subprocess.check_call([sys.executable, "-m", "pip", "install", package])

This method ensures that you are calling the pip associated with the current Python runtime.

Caution: Programmatic Use of Pip Not Supported

It's important to note that since pip version 10, all code has been moved to pip._internal. This is indicative of the fact that programmatic use of pip is not supported. Therefore, it is recommended to adhere to the recommended method for installing modules within code.
