Poetry: AttributeError: Table object has no attribute decode in urllib parse

[pawamoy]

• [x] I am on the latest Poetry version.
• [x] I have searched the 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: Red Hat Enterprise Linux Server 7.6 (Maipo)
• Poetry version: 1.1.1 and 1.1.0
• Python version: 3.6.12 (same with 3.6.11)

RHEL is known for packaging custom versions of Python, but in this case I installed Python with pyenv, so it should be the main, official Python version (or maybe pyenv installs the RHEL version as well? I doubt it)

Issue

Poetry 1.1.0rc1, 1.1.0b4 and 1.1.0b3 work fine.

Poetry 1.1.1 and 1.1.0 fail with an AttributeError: 'Table' object has no attribute 'decode' in urllib/parse.py

Poetry 1.1.1:

$ poetry lock -vv

Does this happen only when locking?

Can you please post the source configuration from your pyproject.toml as well as the output of poetry config repositories (sanitised ofcourse).?

[pawamoy]

OK I think I know why it happens. I had some left overs in Poetry's global config:

[repositories.private_pypi_a]
[repositories.private_pypi_a.url]
url = "https://some_private_pypi_a_url"

Newest repositories were added like this:

[repositories.private_pypi_b]
url = "https://some_private_pypi_b_url"

After removing the left-overs, everything works fine, in previously mentioned versions: 1.1.0, 1.1.1, and 1.1.2.

Thank you for pointing/forcing me to check my global Poetry config @abn, it solved the issue for me 😄 🎉 !
