Link object being passed instead of Path to poetry.core.packages.file_dependency.FileDependency in poetry-core 1.0.5

[mrogaski]

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

Issue

I can easily reproduce the issue moving from poetry-core 1.0.4 to 1.0.5, where I have the project directory and the Poetry cache directory on separate volumes (where there is no absolute path to the cache directory from the CWD). I can also reproduce the problem where the cache and CWD are co-located on a drive mapped with the SUBST command, likely because the cache is showing up as being on a different volume.

This is in a freshly cloned poetry-core project.

Same here! I have to empty my .cache/pypoetry to make it work.

I had the same issue because I had recently pinned poetry but not poetry-core.

I had poetry pinned to 1.1.7, which worked with poetry-core-1.0.5. After poetry-core was updated to 1.0.6, poetry 1.1.7 stopped working and starts to exhibit the behaviour described above.

@mrogaski Seeing that you are using poetry-core-1.0.5 try to update poetry-core to 1.0.6 and see if that solves that issue for you, too.

Thanks for this last comment, indeed I did not notice that poetry-core was not locked if I lock poetry itself. And this resulted in poetry-core version slowly drifting until it was no longer compatible. This looks like yet another hole in the net somehow, though?

[mrogaski]

No, 1.0.6 is also impacted.

Also experiencing this on poetry 1.1.8 + core 1.0.5. Downgrading to 1.1.7 and core 1.0.4 resolved my issue

[mbergal]

Is it possible to install poetry using poetry itself. This would help since poetry respects lock file and would consistently install core 1.0.3 instead of whatever is available at the time of install?

I would install latest poetry into separate location and use it to install the specific poetry version in my environment.

Can you ckeck if #4531 fixes this for you?

[mrogaski]

Can you ckeck if #4531 fixes this for you?

This appears to fix the issue. I was able to reproduce the behavior from the 1.2.0a2 master and I don't encounter the problem with the fix applied.

[vvoody]

I found rm -rf ~/Library/Caches/pypoetry/* work, poetry 1.1.11 and poetry-core 1.0.7.

[papb]

The solution in my case (poetry 1.1.6) was to run rm -rf $HOME/.cache/pypoetry/artifacts/* before poetry install.

[radoering]

Should be fixed via #4531 (poetry 1.2.0b1) and #4549 (poetry 1.1.12).
