regression in tox 4.4.0, creating an invalid constraints.txt file#2898

Issue

tox is creating a constraints file that contains unnamed constraints in this form:

pytest-xdist
pytest<8,>=7.0.0rc1
.[aiosqlite]

this seems like something new, the pip command seems to have been changed and is now failing:

py310-sqlite: install_package_deps> python -I -m pip install importlib-metadata -c/home/classic/tmp/foo/.tox/py310-sqlite/constraints.txt
DEPRECATION: Constraints are only allowed to take the form of a package name and a version specifier. Other forms were originally permitted as an accident of the implementation, but were undocumented. The new implementation of the resolver no longer supports these forms. A possible replacement is replacing the constraint with a requirement. Discussion can be found at https://github.com/pypa/pip/issues/8210
ERROR: Unnamed requirements are not allowed as constraints

Environment

Provide at least:

  • OS: linux
  • pip list of the host Python where tox is installed:

DEPRECATION: Constraints are only allowed to take the form of a package name and a version specifier. Other forms were originally permitted as an accident of the implementation, but were undocumented. The new implementation of the resolver no longer supports these forms. A possible replacement is replacing the constraint with a requirement. Discussion can be found at https://github.com/pypa/pip/issues/8210
