poetry 1.2.0a1: AttributeError when installing package from secondary repo

• 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).

• OS version and name: macOS 10.15

• Poetry version: 1.2.0a1

Issue

Hi! I’m testing new 1.2.0a1 version as an early-adopter to find potential issues.

My pyproject.toml defines a secondary repo:

[[tool.poetry.source]]
name = "XXX"
url = "https://pypi.XXX.YYY"
secondary = true

And I have one dependency which comes from this private pypi repo. Poetry 1.1.3 installed it without errors, but on 1.2.0a1 I get this stacktrace:

  • Installing FOOBAR (1.7.2): Pending...
  • Installing FOOBAR (1.7.2): Failed

  Stack trace:

This regression appeared in Poetry 1.1.7/1.1.9 two days ago when poetry-core 1.0.5 was released. Downgrading to poetry-core 1.0.4 is a workaround.

I had the same issue, with poetry 1.1.11, I downgraded poetry to 1.0.6 and it worked, but that was not the permanent solution as 1.1.11 brought new features, which were really handy in building/publishing wheels. After some research I found that poetry’s local cache was getting corrupted, since I built the packages multiple times. So I needed to delete the cache and it started working again like a charm.

To find the cache location poetry config --list

delete the cache directory containing the private repository. Or run poetry cache clear repo-name --all

delete the virtual-env from your project run poetry install/update again it will work.

Please Have a look https://github.com/python-poetry/poetry/issues/1631 I think that’s the reason why we are having this problem at first place.
