Python poetry install failure - invalid hashes

I'm unsure exactly what information / context to provide with this post in order for it to be
properly answered - so if I can add more information please let me know.

Whilst trying to install a package I've had an error message as follows:

  Invalid hashes (sha256:01d6b62184e55367ce7d770bd87d97a6cfaf783ff7ba8328e7473a339fe19807) for numpy (1.22.2)

I don't know how to go about troubleshooting this problem.

poetry --version
(install-check-clU745_7-py3.8) ➜  install_check poetry --version
Poetry version 1.1.12

poetry env info
Output of poetry env info:

Steps to reproduce
Here is an attempt to clearly outline a reproduction of this problem:

python --version
    Python 3.8.12

which python
    /Users/user_name/.pyenv/shims/python

poetry new install_check
    Created package install_check in install_check

cd install_check

cat pyproject.toml| grep python
    python = "^3.7"

# update pyproject.toml to 3.8 instead of 3.7.

cat pyproject.toml | grep python
    python = "^3.8"

python --version
    Python 3.8.12

poetry env use python3.8

which python3.8
    /Users/user_name/.pyenv/shims/python3.8

poetry env use python3.8
