How to Install Python Packages on Raspberry Pi Easily

To install Python packages on Raspberry Pi, use the pip command in the terminal, like pip install package_name. For Python 3, use pip3 install package_name to ensure the package installs for Python 3.

📐

Syntax

Use the pip tool to install Python packages. The basic syntax is:

pip install package_name - installs a package for Python 2 (if installed).
pip3 install package_name - installs a package for Python 3, which is the default Python on Raspberry Pi OS.
You can add --user to install packages only for your user without needing admin rights.

bash

pip3 install package_name

💻

Example

This example shows how to install the popular requests package for Python 3 on Raspberry Pi.

bash

pip3 install requests

Output

Collecting requests Downloading requests-2.31.0-py3-none-any.whl (62 kB) Installing collected packages: requests Successfully installed requests-2.31.0

⚠️

Common Pitfalls

Some common mistakes when installing Python packages on Raspberry Pi include:

Using pip instead of pip3 when Python 3 is needed, causing packages to install for Python 2 or fail.
Not having pip3 installed. You can install it with sudo apt update && sudo apt install python3-pip.
Trying to install packages without sudo when system-wide installation is needed, leading to permission errors.
Not updating pip itself, which can cause installation errors. Update with pip3 install --upgrade pip.

bash

Wrong:
pip install requests

Right:
pip3 install requests
