Constraints behaviour changes in new PIP

See original GitHub issue

We have this warning when running the latest PIP, so we have to take a close look what it means to us:

pip install 'https://github.com/apache/airflow/archive/master.tar.gz#egg=apache-airflow[devel_ci]' 
--constraint https://raw.githubusercontent.com/apache/airflow/constraints-master/constraints-3.6.txt
DEPRECATION: Constraints are only allowed to take the form of a package 
name and a version specifier. Other forms were originally permitted
as an accident of the implementation, but were undocumented. The new implementation
of the resolver no longer supports these forms. A possible replacement is replacing
the constraint with a requirement.. You can find discussion regarding 
this at https://github.com/pypa/pip/issues/8210.

It’s not this. In our case we simply need to use --requirement instead of --constraint - we have the same result and it is officially supported in PIP.

Actually I think it was this. I have not seen this since I implemented the “@” (it was automatically overwritten before I merged it, so I think this was false-negative). I am provisionally closing it.
