How to Avoid the \'error: externally-managed-environment\' When Using pip3?

Avoid "error: externally-managed-environment" While Using Pip 3

The error "error: externally-managed-environment" arises when attempting to install Python packages system-wide using pip install xyz, indicating an externally managed environment on Linux machines. To resolve this issue, consider the following:

Preferred Solution: Using a Virtual Environment

The best practice for installing Python libraries and applications is to isolate them in a Python virtual environment. This prevents interference with other system components.

• Using Pipx for Applications:
  For applications, install pipx as a system package:

  apt install pipx
  pipx install some-python-application

• Creating a Virtual Environment Yourself:
  Create a virtual environment using venv and install libraries within it:

  python -m venv my-venv
  my-venv/bin/pip install some-python-library

Alternative Solution: System-Wide Installation

In exceptional cases, if system-wide installation is necessary, consider the following options:

• Using Pip's --break-system-packages Flag:
  Run pip install xyz with the --break-system-packages flag, but be aware that this may compromise system stability.

• Adding to Pip's Configuration:
  Add the following lines to ~/.config/pip/pip.conf:

  [global]
  break-system-packages = true
