Not succeeding in getting the system running

[pietercardoen]

Dear

I got this message when trying to run the "mix phoenix.server" command

ERROR in ./web/elm/Main.elm
Module build failed: Error: Compiler process exited with error Compilation failed
Could not find package elm-lang/navigation.

Maybe your elm-stuff/ directory has been corrupted? You can usually fix stuff
like this by deleting elm-stuff/ and rebuilding your project.

Please help me. I would like to make a dockerized environment to test this.

Best regards
