Python version mismatch only installs non-dev dependencies #1139

Open my1e5 opened 3 months ago

my1e5 commented 3 months ago

Usually, when working on my rye-managed projects, if I change the .python-version I always run rye sync afterwards and all is fine.

But if I don't run rye sync things are also usually fine. It will detect a Python version mismatch and re-initialise the virtualenv.

Until I came across this error. If I change the .python-version and then immediately run a command such a rye run mypy . - where mypy is one of my dev-dependencies in my pyproject.toml. It will detect the Python version mismatch but it seems to only install the non-dev dependencies. 

❯ rye run mypy .

It didn't install mypy. Those packages are all my normal dependencies. It didn't install any dev dependencies.

The reason I found this out is because it's causing my CI workflow to fail - https://github.com/eifinger/setup-rye/issues/263

Is there a reason why dev-dependencies aren't installed in this case? Is it a bug?
