installs via environment files failing

[ras44]

Describe the bug

This is a follow up on the work being done in #778 to list and address a variety of ongoing issues related to the pre-defined environment files in envs/:

• should env files contain a relative reference to the current source? ... as shown in envs/environment-py39.yml:
  

• or a fixed version, as shown in envs/environment-py38.yml:
  

• I would vote in favor of a fixed version

  • follow up: should we update to the latest release 0.15.1 ?

  • environment-py38.yml
    
  • environment-py39.yml
    

The failures in our Github workflows largely appear related to:

Building on other platforms like Ubuntu on Windows, we see other failures, likely related to the build environment and cython.
