Bug: Broken SAM CLI v1.134.0 on MacOS Intel CPU

[dmitrikozlov]

Description:

Running the GUI installer (aws-sam-cli-macos-x86_64.pkg) for SAM as described here leads to a broken state where the SAM CLI cannot be called at all.

Steps to reproduce:

1. Download installer
2. Verify installer
3. Run installer
4. Verify CLI running sam --version
5. Observe the error

Observed result:

[PYI-32442:ERROR] Failed to load Python shared library '/usr/local/aws-sam-cli/_internal/libpython3.11.dylib': dlopen: dlopen(/usr/local/aws-sam-cli/_internal/libpython3.11.dylib, 0x000A): Symbol not found: (_mkfifoat)
  Referenced from: '/usr/local/aws-sam-cli/_internal/libpython3.11.dylib'
  Expected in: '/usr/lib/libSystem.B.dylib'

Expected result:

> sam --version
SAM CLI, <latest version>

Alternative steps

1. Remove sam as described here
2. Just in case there is a brew-installed version left over

>brew uninstall aws-sam-cli
Error: No such keg: /usr/local/Cellar/aws-sam-cli

3. Create a python virtual environment and activate it python -m venv env; source env/bin/activate
4. Run pip install aws-sam-cli
5. >sam --version
6. Observe the same error ... Symbol not found: (_mkfifoat)

Additional environment details

1. macOs Monterey v 12.7.6, Intel CPU

Hello @dmitrikozlov ,

Thank you for bringing this to our attention. The issue you're experiencing appears to be system-specific. To troubleshoot, could you please try the following steps:

Install version 1.132.0 of the AWS SAM CLI from this link: https://github.com/aws/aws-sam-cli/releases/tag/v1.132.0
Please let us know if the issue persists with this version.

If the problem continues, we recommend creating a virtual environment (venv) and installing the SAM CLI using pip. You can find the package here: https://pypi.org/project/aws-sam-cli/

Alternatively, updating your MacOS to the latest version might resolve the issue.

Please try these steps and let us know the results. We're here to help if you need further assistance.

Hello @vicheey,

I tried to install version 1.132.0 from the pkg file. The result was the same:

$ sam --version
[PYI-85114:ERROR] Failed to load Python shared library '/usr/local/aws-sam-cli/_internal/libpython3.11.dylib': dlopen: dlopen(/usr/local/aws-sam-cli/_internal/libpython3.11.dylib, 0x000A): Symbol not found: (_mkfifoat)
  Referenced from: '/usr/local/aws-sam-cli/_internal/libpython3.11.dylib'
  Expected in: '/usr/lib/libSystem.B.dylib'

I tried installing SAM with pip earlier, but that didn't work as described in the ticket. So I ran pip to install version 1.132.0, and that worked!
pip install aws-sam-cli==1.132.0

Unfortunately, MacOS Monterey is not officially supported anymore (last official patch from Apple was over 7 months ago), so many of SAM CLI dependencies started dropping support for it too.

It's good that installing 1.132.0 through pip worked though. You can continue using that version until you upgrade your version of MacOS.

I don't have access to an environment with that version of MacOS, but I wonder if the latest version of SAM CLI can work in an older version of Python (like, installing SAM CLI 1.134.0 in Python 3.9 instead of 3.11). You might want to try that if you ever need one of the features in newer versions of SAM CLI before upgrading your OS.

I'm resolving this issue.
