Pip From REPL

Run pip to install packages from the Python interactive shell aka REPL.

The benefit of pipfromrepl is that the user doesn't need to know how to navigate the command line or have their PATH environment variables set up. If multiple versions of Python are installed, pipfromrepl uses the pip module associated with the currently running interactive shell. The goal of pipfromrepl is to reduce the number of steps that students and beginners need to take to get Python packages installed on their computer.

Installation

To install pipfromrepl from the REPL, copy and paste the following into the REPL:

import subprocess, sys; subprocess.run([sys.executable, '-m', 'pip', 'install', 'pipfromrepl'])

Pipfromrepl works on Python 2.7 and Python 3.4+ (the versions of Python that come with the pip module.)

To install with pip from the command line, run:

pip install pipfromrepl

The uninstall() function has a confirm keyword argument you can set to True to force the user to manually enter Y to proceed.

The user_install() function passes the '--user' argument to pip.

You can pass pip commands to pip directly with the pip() functions:

>>> import pipfromrepl
>>> pipfromrepl.pip('install pymsgbox')

There's also a pipenv() function that runs pipenv instead of pip. It works the same as pip().
