I am trying to set up CI in github workflows. I have followed the suggestions in https://discourse.julialang.org/t/easy-workflow-file-for-setting-up-github-actions-ci-for-your-julia-package/49765. The complication is that my package uses PyPlot. Following an example from somewhere (sorry, I forget where) I have specified the following in my ci.yml
env:
PYTHON: ""
(what does specifying an empty string here imply?)
CI completes successfully for ubuntu and windows but fails on maxOS with the following error
INTEL MKL ERROR: dlopen(/Users/runner/.julia/conda/3/lib/libmkl_intel_thread.1.dylib, 9): Library not loaded: @rpath/libiomp5.dylib
126
Referenced from: /Users/runner/.julia/conda/3/lib/libmkl_intel_thread.1.dylib
127
Reason: image not found.
Presumably similar to https://discourse.julialang.org/t/intel-mkl-fatal-error-with-pyplot/36737
Any suggestions on how I might correct this for CI?
