setuptools 45 installed on Python 2 with anaconda

[dbl001]

I am running Anaconda Python on OS X as well as Ubuntu.

My base Ananaconda environment on OS X is is 2.7.
How can I upgrade it?
When I try to save my environments to .yaml file I get python 2.7 errors.

$ conda -V
conda 4.8.2

 $ pip -V
pip 20.0.2 from /Users/davidlaxer/anaconda/lib/python2.7/site-packages/pip (python 2.7)

$ conda list setuptools
# packages in environment at /Users/davidlaxer/anaconda:
#

setuptools                45.0.0                   py27_0    conda-forge

$ conda env export > environment.yaml

I can't really tell what's going on here, and it's very hard to do so without a clean reproducer. It seems like in some cases you're getting setuptools 45 installed on Python 2 and in other cases you are getting the Python 2 warning on Python 3?

The first one might be a duplicate of #1458, and there's some anaconda-specific thing that's ignoring the python_requires metadata. The second one might be more interesting.

My Anaconda base environment is 2.7. Is there a way to upgrade this to 3.7 without starting from scratch (e.g. - recreating all my virtual environments - which I can’t seem to save to a .yaml file)? It’s curious that this is happening on OS X as well as on Ubuntu.

Is there a way to upgrade [my Anaconda base environment] to 3.7?

This team is not familiar with Anaconda, so I'd reach out to that team for guidance on that.

On your Ubuntu system, the fact that you're getting the py2 warning for a file in the python3.6 source tree suggests to me that something (Anaconda maybe) has caused Python 2 to link to your Python 3 site packages. You'll want to inspect sys.path and possible do some debugging with python -v or tracing of import site to determine where or how that's happening. Also check that the environment variable PYTHONPATH isn't somehow implicated.

For your OS X environment, where you have Python 2, it may be the case that all you need to do is use conda to downgrade to setuptools<45.
