AssertionError while running poetry lock

[mboutet]

• I am on the latest Poetry version. Actually, I installed 63c86bf using curl -sSL https://install.python-poetry.org | python3 - --git https://github.com/python-poetry/poetry.

• 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 Monterey (12.4 (21F79))

• Poetry version: 63c86bf

• Link of a Gist with the contents of your pyproject.toml file:

  • pyproject.toml that does not work
  • pyproject.toml that works

Issue

When I run the pyproject.toml that does not work, I get the following exception:

duplicate #5791, already fixed

[mboutet]

@dimbleby, as mentioned in the description, I installed poetry 63c86bf (master branch of yesterday) using:

curl -sSL https://install.python-poetry.org | python3 - --git https://github.com/python-poetry/poetry

Unless it did not actually install the version from master, then #5791 is not, in fact, fixed.

[dimbleby]

The fix was not in this project but in its sister, poetry-core - and it is, in fact, fixed.
