Poetry install fails with EnvCommandError: looks for version 2020.12.21.3-lambda, why?

Viewed 8931

Poetry cannot complete any install or add without throwing an EnvCommandError having to do with not being able to find a setup.py for soupsieve.

It looks for version "2020.12.21.3-lambda" and I don't understand why it's not loading the dependency from a remote source with a normal version like the other dependencies.

This package has worked just fine for some time. I don't remember changing anything in the pyproject.toml. I tried checking out an old version of pyproject.toml to see if maybe something had changed accidentally. Same result.

I also tried deleting the .venv/ Poetry creates and recreating it. Same result.

I have no idea where soupsieve is coming as a dependency. It installs just fine using plain old pip inside the environment poetry creates.

cd project/
poetry shell
pip install soupsieve # Installs 2.1 without a problem

I had this same error because for some reason poetry install always failed to create a virtual enviroment path in %APPDATA%. The solution was to move the venv to the local project root.

poetry config virtualenvs.in-project true
poetry env remove python
poetry install

Quick fix

So the root problem had nothing to do with poetry, but I was able to at least unblock myself from this issue by explicitly adding the sub-dependency with a specific version.

pip add soupsieve==2.1

Root problem

The real problem was that our systems proxy everything through a private artifact repository that had been poisoned with bad metadata: it contained things named soupsieve that were not actually soupsieve.

Once we removed these things, poetry went back to working well.
