Bug report: tests fail locally with Pyomo and Cbc

[elenya-grant]

Cbc version error with dispatch for local runs

When I run tests locally, any test that uses Pyomo fails because of a cbc error. I've followed installation instructions and am not sure what causes this issue. Tests pass on GitHub actions but fail on my machine.

How to reproduce

1. create environment using dependency information below or follow install instructions in README.md
2. run pytest tests/hopp/test_custom_financial.py::test_hybrid_detailed_pv_with_wind_storage_dispatch

Relevant output

   pyomo.common.errors.ApplicationError: Solver (cbc) did not exit normally

   ../../../opt/anaconda3/envs/hopp_v4/lib/python3.11/site-packages/pyomo/opt/base/solvers.py:628: ApplicationError

   pyomo.opt:solvers.py:620 Solver (cbc) returned non-zero return code (-6)
