Having the same issue with Github Action. Did you find a solution?

Edit: found solution in #74. You have to install coveralls package instead of python-coveralls.

Yes, I found the same solution.

Same problem on Travis.

These exceptions are not specific to AppVeyor and still occur today. Executing within GitHubActions workflow with Py 3.8, 3.9, 3.10, 3.11 and installation from conda-forge:

Without installation of either coveralls or python-coveralls, get missing package, as expected.
With only coveralls 1.8.0 installed (from conda-forge), get the identical Exception in the title of this issue.
With only python-coveralls 2.9.3 installed (from conda-forge), get the identical Exception in the title of this issue.

Here's an Exception trace from one of the workflows.

ImportError: cannot import name 'Reporter' from 'coverage.report' (/home/runner/micromamba-root/envs/anaconda-test-env-py-3.8/lib/python3.8/site-packages/coverage/report.py)
Error: Process completed with exit code 1.

The coverage package reports that coverage.report.Reporter has been deprecated in release 5.0. Current release (just a few days ago) is 7.0.

It is coveralls/report.py, line 6 that calls from coverage.report import Reporter. That's the problem.

To avoid this problem now, should we pin coverage<5 when using coveralls? This still fails with a conda/micromamba install. Switching to pip install for these two packages. And this worked.

Summary: Do not install coverage and coveralls with conda, use pip. And do not install python-coveralls at the same time.
