Resolving the Unable to Install Matplotlib Issue in AWS Lambda Docker Base Images

If you are working with AWS Lambda functions that utilize Docker images, you might encounter some common issues when attempting to install libraries like matplotlib. One particular problem arises due to missing compiler tools in the AWS-provided base image for Python. In this post, we'll explore this issue and present a straightforward solution.

The Problem: Installation Errors

While building your Docker image with the AWS Lambda Python 3.8 base image, you might face installation errors when trying to install matplotlib. Specifically, you may see messages indicating that gcc (the GNU Compiler Collection) is unable to execute certain tasks, resulting in an inability to compile the library properly.

Here’s what a typical Dockerfile might look like:

Running this Dockerfile could yield errors like:

These errors primarily indicate that critical build tools required by the matplotlib library are not available in the base image.

Solution: Installing Development Tools

The root of the problem lies in the absence of necessary development tools in the Docker image. To resolve this issue, you need to add these tools before attempting to install matplotlib. The solution involves modifying your Dockerfile.

Steps to Fix the Issue

Follow these steps in your Dockerfile:

Add Development Tools: You need to install a group of development tools that include essential compilers and libraries needed for building projects like matplotlib.

Update Your Dockerfile: Modify your Dockerfile to include the following commands:

Explanation of Commands:

yum -y groups mark install "Development Tools": This command marks the 'Development Tools' package group for installation.

yum -y groups mark convert "Development Tools": Converts the marked package group into installable packages.

yum -y group install "Development Tools": This command installs all of the necessary development tools, including compilers, which are crucial for matplotlib installation.

Conclusion

With these changes, you should be able to build your Docker image without encountering the previous installation errors. The addition of compiler tools resolves the issue and allows you to harness the power of matplotlib within your AWS Lambda functions.

If you continue to experience any problems or have further questions, don't hesitate to reach out for assistance!
