BUG

If a dependency contains - in its extras field, they can't be installed if the package is built with poetry build and then pip install <package>. It gives a warning and doesn't install those extra packages

Steps

• I have added my dependency to pyproject.toml with poetry add sktime[all_extras,dl]==0.15.0
  which added to toml as: sktime = {version = "0.15.0", extras = ["all-extras", "dl"]}
• I have built the project with poetry build
• I have installed the built package with pip install <my_built_package.tar.gz>
• Here I got the error that says:
  WARNING: sktime 0.15.0 does not provide the extra 'all-extras'
• And those extra packages didn't installed at the end.

Notes

• I can successfully install pip install sktime[all_extras, dl]
• In the built package, PKG-INFO has the following content:
  • Requires-Dist: sktime[all-extras,dl] (==0.15.0)
  • I have changed it to Requires-Dist: sktime[all_extras,dl] (==0.15.0). But it gave the same warning again.
