ModiaMath has three released versions and all are registered at METADATA. Modia uses ModiaMath and has ModiaMath in its dependencies (in Project.toml/Manifest.toml file). Modia is cloned to .julia/dev, the current environment (.julia/environments/v1.0) is deleted and Julia 1.0.0 is started newly. The following gives an error (log of session):
