Thanks for the hint. Now it breaks with another package.

-- NO VALID PACKAGE VERSION ----------------------------------------------------
Because NoRedInk/elm-json-decode-pipeline does not appear to exist and this
project depends on NoRedInk/elm-json-decode-pipeline 1.0.0, no valid set of
package versions could be found.
It seems if it couldn’t access the package repo. I wonder how I can debug that.
