Updating All Packages In A Virtual Enviroment

The easiest way to update unpinned packages (i.e., packages that do not require a specific version) in a virtual environment is to run following Python script that makes use of pip:

import pkg_resources
from subprocess import call

for dist in pkg_resources.working_set:
    call("python -m pip install --upgrade " + dist.<projectname>, shell=True)

 

Updating All Packages In A Pipenv Environment

The simplest way to update all the unpinned packages in a specific virtual environment created with pipenv is to do the following steps:

1. Activate the Pipenv shell that contains the packages to be upgraded:

pipenv shell

pipenv update
