Matplotlib dependency for Documenter.jl in Github Actions

[sostock]

@kellertuer

env:
    PYTHON: ""

(See Plotting Recipe for data on S2 and H2 by kellertuer · Pull Request #245 · JuliaManifolds/Manifolds.jl · GitHub for the error and Plotting Recipe for data on S2 and H2 by kellertuer · Pull Request #245 · JuliaManifolds/Manifolds.jl · GitHub for how I tried to set it)

You have to set the environment variable at the step where the package is built. In your documenter.yml, that is one step later (in julia-actions/julia-docdeploy@v1 instead of julia-actions/setup-julia@latest).

@kellertuer

ENV["PYTHON"] = ""

within Julia, the error persists and it’s still looking in the CIs VM in usr/local/bin for a python , see Plotting Recipe for data on S2 and H2 by kellertuer · Pull Request #245 · JuliaManifolds/Manifolds.jl · GitHub for the commit and Plotting Recipe for data on S2 and H2 by kellertuer · Pull Request #245 · JuliaManifolds/Manifolds.jl · GitHub for the error).

Setting the environment variable in the make.jl file is also not helpful, the package is already built when this is executed.
