[macos] poetry add fails when file or path is in /tmp or /var

• Poetry version: 1.2.2

• Python version: 3.9.13

• OS version and name: macOS 12.1

• pyproject.toml: pyproject.toml

• I am on the latest stable Poetry version, installed using a recommended method.

• I have searched the issues of this repo and believe that this is not a duplicate.

• I have consulted the FAQ and blog for any relevant entries or release notes.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

Issue

When the file or path is is /tmp or /var on macos, poetry add /path/to/file.whl fails silently. When rerun with -vvv we get an AssertionError in mixology/partial_solution.py:_register (full stacktrace here). This is the same symptom as https://github.com/python-poetry/poetry/issues/6054, which is marked solved. This also has different repro steps.

Repro:

• mkdir /tmp/bar
• pip download -d /tmp/bar requests
• poetry add /tmp/bar/requests-2.28.1-py3-none-any.whl`

Note that pip install works here as does poetry add /private/tmp/bar/requests-2.28.1-py3-none-any.whl

Start with the AssertionError in mixology/partial_solution.py:_register and reproduce it using the listed /tmp and /private/tmp wheel paths. Compare the failing poetry add command with the working pip install and private-path invocation; done means poetry add succeeds for the /tmp path without silently failing or raising the assertion.
