[BUG: No arguments expected for "install" command, got "." watson@MacBookPro mistral-inference % poetry install .

Python -VV

Python 3.13.3 (main, Apr  8 2025, 13:54:08) [Clang 17.0.0 (clang-1700.0.13.3)]

apparently poetry doesn't like ".". I dunno, I don't use poetry. 

This is macos Apple Silicon on M1 Pro. FWIW, recommend using the rust invasion or innovation? of python tooling gone awry with uv, which goes a lot further, a lot faster. Armen Ronacher can't be wrong.

Thanks!

Note: This error originates from the build backend, and is likely not a problem with poetry but one of the following issues with rpds-py (0.18.1)

- not supporting PEP 517 builds
- not specifying PEP 517 build requirements correctly
- the build requirements are incompatible with your operating system or Python version
- the build requirements are missing system dependencies (eg: compilers, libraries, headers).

You can verify this by running pip wheel --no-cache-dir --use-pep517 "rpds-py (==0.18.1)".
