Configuring Pip to Work in Enterprise Environments

The hardest thing about using package managers within an enterprise is getting them to download the packages you need on the office network. Oftentimes, you are hindered by SSL errors, and other times you get bogged by DNS errors.

Downloading External Packages

Most of us either disable SSL verification at this point or contact IT about getting trusted certificates. The former is a bad idea. The second option is not bad, but it does lead down the rabbithole of “why do you need this package?”

Instead, you should know that you can easily set some environment variables to help with this.

export HTTP_PROXY=http://<username>:<password>@<>:<port>
export http_proxy=$HTTP_PROXY
export HTTPS_PROXY=http://<username>:<password>@<>:<port>
export https_proxy=$HTTP_PROXY

This works for most tools. Some tools follow the Windows way, utilizing the uppercase values, and some use the lowercase. Now that’s food for thought. If you are writing your own tool that works with the internet, make sure to support both methods. This helps your users’ experience greatly.

The above settings should solve your dns issues, but they won’t help the SSL errors. For that, you will need to configure your tools specifically.

For pip, the easiest way is to use the configuration file. Before you do that, however, ensure you have updated pip to the latest version.

python3 -m pip install -U pip


python   pip
