Astroquery: Problem installing clean astroquery

[tomdonaldson]

I'm getting an error trying to install a clean version of astroquery. Hopefully it's a transient issue and will resolve itself shortly, but if not here is what I did:

conda create --quiet --yes --name try_astroquery python=3.8
conda activate try_astroquery
pip install --pre astroquery

The error is:

ERROR: Requested astroquery from 
https://files.pythonhosted.org/packages/65/41/3cc633331a276f78aa5fa110c7dc71e146dd7d14346f3460534a264e0a5d
/astroquery-0.4.2.dev6449.tar.gz#sha256=df7786a5ba87c966f705f6fce02d73bd7c48a748d7e0a89f0531bcd544a7a074
has different version in metadata: '0.4.2.dev0'

I see that astroquery is still using astropy-helpers to generate the version:

https://github.com/astropy/astroquery/blob/fc70b94d13fa44789fe69e133bc264eff872d97a/setup.py#L68-L69

This issue might be naturally solved by applying APE 17 (#1668).

I don't see this error, and can't recall anyone else running into it. What is your pip version? (I'm not on the latest one, so would guess this may be a side effect of the new resolver).

For me, no error with pip 20.2.4 but same error with pip 20.3.1. (pip was installed with conda in Python 3.8 env.)

oh, great, I see a new 🔥 on the horizon.

What was still on my todo list is to tag 0.4.2, so I'll get to it hopefully during the weekend, and I believe that would be the quickest workaround (the CD is broken at the moment anyway, so this issue would not pop up for the near future anyway).

Thanks @tomdonaldson for reporting this
