The only reason I had even updated pip was because of this pip bug which was blocking the IPython package. ![]() I was installing alembic=1.4.2 (which is a pinned dependency for airflow 1.10.12) when I got this inexplicable setuptools error - even though I made sure to explicitly target the python36 pip and not the system pip. I fixed this by simply reverting to the default version. Like you, I had also updated my pip from the default that comes with the python36 package, although only the per-user module, not with sudo. I just ran into this in the very same EC2 AMI when trying to install a package from source.
