sproctor@nickel:~/Code/ScrapReceipts$ elm-package install elm-community/list-extra
To install elm-community/list-extra I would like to add the following
dependency to elm-package.json:

    "elm-community/list-extra": "7.1.0 <= v < 8.0.0"

May I add that to elm-package.json for you? [Y/n] y

Error: I cannot find a set of packages that works with your constraints.

One way to rebuild your constraints is to clear everything out of the
"dependencies" field of elm-package.json and add them back one at a time with
`elm-package install`.

I hope to automate this in the future, but at least there is a way to make
progress for now!
