I think the fix for this has been merged in as part of: https://github.com/UnitedIncome/serverless-python-requirements/pull/446

I'm not sure when this will be made part of a release, but I'm hoping soon as I'm stuck with the same issue and am unable to use serverless-python-requirements without workarounds at this time.

I'm hoping to get a build out shortly. 🤞 Closing this as the fix is merged.

Poetry version 1.0.3

$ serverless deploy
Serverless: Generating requirements.txt from pyproject.toml...

  Error --------------------------------------------------

  Error: ENOENT: no such file or directory, link '/.......

I have to do a poetry export manually before deploying in order to fix this issue.
