Failure to install version 0.4 with pip>=10.0.0 on Python 2.7
This was caught by our CI. The relevant error message is:
Missing build time requirements in pyproject.toml for importlib_resources from https://files.pythonhosted.org/packages/cd/d7/47a35e84a4f48aece34095f7c02da3100384fc6400a8139f88a18023f34f/importlib_resources-0.4.tar.gz#sha256=dcfa996d4f988c5a4244c5a62c3decfc01488a19afa459726eac47ed41ec0c1d (from memote==0.6.2): 'setuptools' and 'wheel'.
This version of pip does not implement PEP 517 so it cannot build a wheel without 'setuptools' and 'wheel'.
Could not find a version that satisfies the requirement flit (from versions: )
No matching distribution found for flit
Either importlib_resources==0.3 or pip<10.0.0 work just fine.
