- [x] I am on the [latest](https://github.com/python-poetry/poetry/releases/latest) Poetry version. - [x] I have searched the [issues](https://github.com/python-poetry/poetry/issues) of this repo and believe that this is not a duplicate. - [x] If an exception occurs when executing a command, I executed it again in debug mode (`-vvv` option). - **OS version and name**: Arch Linux - **Poetry version**: 1.2.0a2 ## Issue See behaviour:  Looking at -vvv output, only thing I can find mentioning the custom package name: ``` gitlab-24844347: 1 packages found for alpaca-api-client >=0.9.2,<0.10.0 1: fact: alpaca-api-client (0.9.2) depends on pydantic (>=1.8.2,<2.0.0) 1: fact: alpaca-api-client (0.9.2) depends on requests (>=2.25.1,<3.0.0) 1: fact: alpaca-api-client (0.9.2) depends on websockets (>=8.1,<9.0) 1: selecting alpaca-api-client (0.9.2) ``` Encountered this while investigating #3855 which may be related.
