Issue

I’m facing this issue when building my poetry project using the new poetry-core. When looking a little deeper, it seems like the fix in commit was not applied to poetry-core.

I would love to help out with a PR, but will need some direction 😃

@darkvariantdivine definitely give you this, this is an interesting issue.

For anyone who is interested in the root case, when tomlkit reads in the toml file, the values of tool.poetry.exclude are of tyle <class 'tomlkit.items.String'>. This in most parts works seamlessly everwhere a string is required. However, it seems that in this particular case, since one of the values (“devops”) is an absolute path, ie. no relative path or glob, pathlib decides to use a code path that ends up triggerring the a call to sys.intern(exclude[0]) and this is what fails.

An immediate workaround would be to use devops/** instead of devops.

Thanks @finswimmer and @abn for this. Poetry is a great tool, I hope it continues to grow!
