[BUG] Python pdk command "Cannot find module '../lib/cli.js'"

[jstrunk]

Describe the bug

When running pdk on a Python monorepo in CodeBuild, I get the error "Cannot find module '../lib/cli.js'".

I’m using feature branch pipelines It happens in CodeBuild in a new branch that worked fine on my local machine. New branches cloned from main continue to work. There are new projects in the .projenrc.py, and some package versions are different. I confirmed that builds from main work with both pdk 0.22.42 and 0.22.44. In troubleshooting, I determined that the pdk command being run in CodeBuild is the one installed by poetry. On my local machine, it also runs the pdk installed by poetry. There’s no difference in yarn.lock.

Expected Behavior

I expect pdk to run successfully.

Current Behavior

Possible Solution

No response

Additional Information/Context

No response

PDK version used

0.22.44

What languages are you seeing this issue on?

Python

Environment details (OS name and version, etc.)

CodeBuild STANDARD_7_0

[jstrunk]

As a workaround, running npx pdk in the buildspec seems to run the globally installed version, and the build succeeds.

When I have had this problem I have removed node_modules and package-lock.json. Then run npx install and the error seems to go away.
