The Install no longer works

[Greg-Boggs]

At first I got an error message that said run:

 cd assets && npm install

That generates lots of errors. But, the mix server still fails with something along the lines of:

[info] Application candidate_website exited: exited in: CandidateWebsite.Application.start(:normal, [])
** (EXIT) an exception was raised:
** (ArgumentError) argument error
