Issue: "TypeError: unhashable type: 'dict'" in Poetry 1.8.x and "TypeError: unhashable type: 'Table'" in Poetry 1.7.0

Issue: "TypeError: unhashable type: 'dict'" in Poetry 1.8.x and "TypeError: unhashable type: 'Table'" in Poetry 1.7.0

I'm encountering different TypeErrors when using Poetry to manage dependencies, even on empty projects. The errors depend on the Poetry version:

With Poetry 1.8.0 or 1.8.4, I get: "TypeError: unhashable type: 'dict'".
With Poetry 1.7.0, I receive: "TypeError: unhashable type: 'Table'".
Here’s what I’ve tried:

Recreated virtual environments using Python 3.13 and 3.12.
Tested on completely fresh projects created through poetry init, yet the errors persist.
Ran tests across various environments: VS Code, PyCharm, and the terminal.
Fully reinstalled Python and Poetry, but the issue remains unresolved.

Does poetry config virtualenvs.path gives you some output? In this directory you may find an envs.toml file which may be corrupt.

Apart from that, your global settings file might be broken. See https://python-poetry.org/docs/configuration/ for the location of the global config.toml.

I referenced a wrong path in my previous response. The envs.toml is expected in /Users/svitlana_tsytsyk/Library/Caches/pypoetry/virtualenvs not in /Users/svitlana_tsytsyk/Library/Caches/pypoetry.

[tsytsyksvitlana]

svitlana_tsytsyk@MacBook-Pro-Svitlana ~ % cd /Users/svitlana_tsytsyk/Library/Caches/pypoetry/virtualenvs
svitlana_tsytsyk@MacBook-Pro-Svitlana virtualenvs % ls
svitlana_tsytsyk@MacBook-Pro-Svitlana virtualenvs % 

[radoering]

So no envs.toml. The content of the config.toml does not look bad, but you can try to delete/rename the config.toml and try again. If you still get an error, you can run the command that raises the error with -vvv and provide the output.
