I get "ERROR: In --require-hashes mode, all requirements must have their versions pinned with ==" when I do "pip install -r requirements"

Question

I get following message at the bottom of cmd line when I try to install some requirements with python 3.6.8 to my folder using "pip install -r requirements.txt"

ERROR: In --require-hashes mode, all requirements must have their versions pinned with ==. These do not:
    importlib-metadata from https://files.pythonhosted.org/packages/71/c2/cb1855f0b2a0ae9ccc9b69f150a7aebd4a8d815bd951e74621c4154c52a8/importlib_metadata-4.8.1-py3-none-any.whl#sha256=b618b6d2d5ffa2f16add5697cf57a46c76a56229b0ed1c438322e4e95645bd15 (from backports.entry-points-selectable==1.1.0->-r requirements-38.txt (line 7))

I already update my pip version to 21.2.4, Does anyone know what might cause and how to solve this? Appreciate!!

Some people report that this is **because of** pip 21, and `pip install pip==20.2.4` fixes it. — Kilian Foth, Nov 10 '21 at 10:44
Any solution with pip 22? Can we just change requirements.txt/Pipfile somehow to fix that? — Eric Burel, Dec 02 '22 at 08:01
