Installing a PyPI module by code

Max Ilinov

Hi!

I'm trying to install a module from PyPI by code and it returns an error.

I've tried this:

import pip
pip.main(['install', 'package_name'])

and it fails with the output:

Traceback (most recent call last):

File "", line 2, in

ImportError: cannot import name 'USER_BASE' from 'site' (/Applications/RoboFont.app/Contents/Resources/site.pyc)

Also, I've tried this:

import sys
import subprocess

output = subprocess.run([sys.executable, "-m", "pip", "install", "package_name"], capture_output=True)

print(output)

and got almost the same report with USER_BASE can't be imported, and also the same with pip show as subprocess.

What I'm doing wrong?
