Install Python Package from .tar.gz File

Installing Python packages from a .tar.gz file is common. This guide will help you do it easily.

What is a .tar.gz File?

A .tar.gz file is a compressed archive. It contains Python package source code. You need to extract and install it.

Prerequisites

Before starting, ensure you have:

• Python installed
• pip installed
• Basic terminal knowledge

Step 1: Download the .tar.gz File

Download the package file from the official source. Save it in a known location.

Step 2: Extract the File

Use the tar command to extract the file. Open your terminal and run:

tar -xzf package_name.tar.gz

This will extract the contents into a folder.

Step 3: Navigate to the Extracted Folder

Use the cd command to enter the folder:

cd package_name

Step 4: Install the Package

Run the following command to install the package:

pip install .

This will install the package using setup.py. Learn more about installing with setup.py.

Alternative Method: Direct Installation

You can also install directly from the .tar.gz file. Use this command:

pip install package_name.tar.gz

This method skips manual extraction.

Common Issues and Fixes

Sometimes, you may face errors. Here are common fixes:

• Missing dependencies: Install them first.
• Permission errors: Use sudo or virtual environments.
• Corrupted file: Re-download the package.

For more on dependencies, see installing with requirements.txt.

Example: Installing a Sample Package

Let's install a sample package step by step.

# Download the package
wget https://example.com/sample_package.tar.gz

# Extract

# Navigate
cd sample_package

# Install
pip install .

Output:

Successfully installed sample-package-1.0

Using Virtual Environments

Always use a virtual environment. It keeps your system clean. Learn how in our local directory guide.
