Amazon SAM CLI discontinuing support for Python 3.7

Published on 2023-10-20

Python 3.7 received end-of-life status in June of 2023. The Amazon SAM CLI will discontinue support for Python 3.7 on October 24, 2023. For more information, see the announcement at the aws-sam-cli GitHub repository.

This change impacts the following users:

  • If you use Python 3.7 and install the Amazon SAM CLI through pip.

  • If you use the aws-sam-cli as a library and build your application with Python 3.7.

If you install and manage the Amazon SAM CLI through another method, you are not affected.

For impacted users, we recommend that you upgrade your development environment to Python 3.8 or newer.

This change does not affect support for the Python 3.7 Amazon Lambda runtime environment. For more information, see Runtime deprecation policy in the Amazon Lambda Developer Guide.
