[6 Proven Fixes] “zipimport.zipimporterror: can’t decompress data; zlib not available”

The zlib library lets Python compress and decompress files. If it’s missing, not configured properly, or has missing files, it triggers the “zipimport.zipimporterror: can’t decompress data; zlib not available” error and stops Python’s compilation function. To fix this error, I’ll provide a comprehensive guide to install and configure the zlib library for fixing this error.

How to Fix zipimport.zipimporterror Issue [6 Easy Ways]

To fix the zipimport.zipimporterror: can’t decompress data; zlib not available error, try checking the Python version, repairing damaged packages, verifying/installing the zlib library, configuring zlib dependencies, and updating the zlib library. Here’s the step-by-step guide to resolve this error on your Linux system:

1. Check Python Packages

The first thing you should do is check whether Python is installed on your system or not. To do so, here are steps to follow:

1. Run the following command in the Terminal window to get the current version of Python:

$ python3 --version

2. Once the command is executed, you’ll see the Python version installed on your system.

3. However, if Python is not installed on your Linux machine, run the following command to install it.

$ sudo apt install build-essential

2. Repaire the Python Package

The damaged Python package can also cause the “zipimport.zipimporterror: can’t decompress data; zlib not available” error. To repair it, follow the steps below:

1. Launch the Terminal and enter the following command:

sudo apt install python3-pip

2. Wait for the repair to complete.

3. Restart your system using the sudo reboot command.

3. Verify the zlib Library

To check whether the zlib library is installed on your Linux system or not, follow these steps to verify:

1. Head to the Terminal window and run the following command:

dpkg -s zlib1g-dev

2. If the zlib library is installed, you will see the version number and other details.

3. However, if you see an error message as the result of this command, this means that you need to install the zlib library package. To do so, run the following command.

sudo apt-get install zlib1g-dev

4. Once it completes the installation process, try checking the zlib library again on your system with the following command. If it’s installed successfully, you’ll see the details of the dpkg zlib library.

dpkg -s zlib1g-dev

4. Install the zlib Library

To install the zlib library and update associated packages on your Linux system, especially if the library is absent or certain packages are outdated, follow these steps:

1. Launch the Terminal on your Linux system, and enter the following command:

sudo apt update && sudo apt install zlib1g-dev

2. Wait for the update and installation process to complete.

3. Restart your system and see if the error is resolved.

5. Configure zlib Dependencies

Sometimes, the missing OpenSSL lib can also cause the zipimport.zipimporterror: can’t decompress data; zlib not available error. To resolve this issue, you need to:

1. In the Terminal app, execute the following command:

sudo apt install libssl-dev

2. Once it completes the installation, check any file compression or decompression with Python to see if the error is fixed.

6. Update the zlib Library

An incompatible version of the zlib library installed on your system can also cause the zipimport.zipimporterror: can’t decompress data; zlib not available error. To update the zlib library, here’s what you need to do:

1. In the Terminal app, run the following command:

sudo apt-get update && sudo apt-get upgrade

3. Wait for the update to complete. Type y if the Terminal prompt asks.

4. Restart your system and see if the problem is fixed.

4 Quick Tips for Preventing the zipimport.zipimporterror Error

The “zipimport.zipimporterror: can’t decompress data; zlib not available” error can cause significant inconvenience, preventing you from running your Python scripts or using certain features. To prevent this error from occurring, follow the tips outlined below:

• 🔄 Keep Your System and Python Packages Up-to-Date: Regularly update your operating system by running the appropriate package manager command (e.g., sudo apt-get update && sudo apt-get upgrade for Debian-based systems) to ensure you have the latest security patches and bug fixes. Additionally, use pip or conda to update your Python packages by running pip install --upgrade package_name or conda update package_name.
• 🔍 Regularly Check the Configuration of Your System and Python Packages: Use commands like ls, pwd, and cat to inspect directories, file paths, and file contents. Verify the configurations of your system and Python packages to ensure they are properly set up. This can help identify and resolve any misconfigurations or installation issues.
• 🌐 Use a Virtual Environment for Python Development: Create a virtual environment using the python3 -m venv env_name command. Activate the virtual environment with source env_name/bin/activate and deactivate it with deactivate. This isolates your Python projects and packages, preventing conflicts and allowing for clean installations and dependencies management.
• 💾 Back-Up Your Python Projects Regularly: Regularly back up your Python projects to avoid data or code loss. Use the cp -r project_dir backup_dir command to create a copy of your project directory. This ensures that you have a duplicate of your project in a separate location, safeguarding against unexpected errors or issues.

Key Takeaways

In conclusion, the “zipimport.zipimporterror: can’t decompress data; zlib not available” error prevents you from running the Python scripts or using certain features on your Linux machine. To fix this error in Python, try solutions such as checking and repairing the Python package, installing and configuring the zlib library, and updating the zlib library. You can avoid this error by keeping packages up-to-date, checking configurations, using virtual environments, and backing up projects.

To become more proficient as a Python developer, you should learn about string-to-float conversion and the None value in Python coding. Understanding how to convert strings to floats allows you to work with numerical data efficiently. Additionally, properly handling None values helps prevent unexpected errors and ensures robustness in your code. However, make sure to check the Python version on your Linux system and update it regularly to access new features, bug fixes, and security patches.
