install error: Could not build wheels for lhotse, which is required to install pyproject.toml-based projects

I'm installing lhotse from source:

pip install -e .

and got following message:

...
 Building editable for lhotse (pyproject.toml) ... done

FYI, I've installed successfully from pypi before, and now I wanna install the newest version for fast loading

I guess it's a version issue? I can install from source by manually editing line 58 in setup.py from IS_DEV_VERSION = True # False = public release, True = otherwise to IS_DEV_VERSION = False # False = public release, True = otherwise

Can you first remove pyproject.toml and retry?
