[BUG] AWS Lambda: package conflicts on install of strands-agents and strands-agents-tools when building a Lambda layer on MacOS

[didier-durand]

Checks

• I have updated to the lastest minor and patch version of Strands
• I have checked the documentation and this is not expected behavior
• I have searched ./issues and there are no duplicates of my issue

Strands Version

0.1.3 for strands-agents & 0.1.2 for strands-agents-tools

Python Version

3.13

Operating System

MacOS Sequoia 15.5

Installation Method

pip

Steps to Reproduce

Run the following command:

pip3.13 install --no-cache --platform manylinux2014_x86_64 --target /tmp/strands-layer/python/lib/python3.13/site-packages --implementation cp --python-version 3.13 --only-binary=:all: --upgrade strands-agents strands-agents-tools

This command is preparing a Linux layer for AWS Lambda from MacOS. Hence the options for cross-build in the pip command.

This command is fully self-container: it should be able to run this command on another Mac and get same results

Expected Behavior

Given the fact that we do not impose any version on the 2 Strands packages, we would expect pip install to complete successfully. But it generates errors: see below.

We use the same kind of pip command for cross-build on other projects and it works. We'd expect the same here.

Actual Behavior

ERROR:

pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.

(note this is not the same case as Cannot install Python dependencies for lambda with correct architecture · Issue #19 · strands-agents/docs).

It seems like the primary problem is:

• uptrace 1.31.0 requires opentelemetry-sdk~=1.31.0
• agents-sdk requires opentelemetry-sdk>=1.33.0,<2.0.0"

which is in conflict. @awsarron is there a specific need for us to depend on 1.33?

[didier-durand]

Hi,

I retested the new version with following command:

pip3.13 install --no-cache --platform manylinux2014_x86_64 --target /Users/didduran/dev/a2a-ui-private/tmp/strands-layer/python/lib/python3.13/site-packages --implementation cp --python-version 3.13 --only-binary=:all: --upgrade "strands-agents>=0.1.4" "strands-agents-tools>=0.1.3"

It still fails: see ERROR below

@didier-durand is there an e2e example we can reproduce with? It seems as if there's un-mentioned dependency somewhere.

Attempting the above command works on my machine:

pip install --no-cache --platform manylinux2014_x86_64 --target ./dependencies --implementation cp --python-version 3.13 --only-binary=:all: --upgrade "strands-agents>=0.1.4" "strands-agents-tools>=0.1.3"

@zastrowm : Hi, thanks for having re-opened this.

Based on the fact that it works on your side, I made additional tests on my side. The situation is following:

1. when I try to build the Lambda Linux layer with the pip command above from within my PyCharm venv (so, with my app package installed in their MacOs version) where I develop my app, It fails with the conflict described above.
2. when I run the command above in a fresh env with no packages of my app installed, it works fine.

So, the issue lies with PyCharm which include MacOS packages when I do the cross-build for Lambda Linux.

Conclusion: this issue is not on Strands Agents side but rather on Pycharm side, which mixes local setup and cross-platform build. So, you can close again - for good. (Sorry for the noise)

Great to hear it's fixed! I found python dependency management to be more complicated than I expected.

Thanks for the initial issue and let us know if you have any other problems.
