elm-package-latest-version: Symbol’s function definition is void: -find #131

When I try to look up documentation for a function, after typing in the package name, I get this error:

elm-package-latest-version: Symbol’s function definition is void: -find

I'm using the latest elm-mode, and I get this error with GNU Emacs 24.5.1 and GNU Emacs 25.3.2.

You're missing the dash dependency, I believe, in which case installing from a package would have avoided this problem.

I installed elm-mode from MELPA using package-install - shouldn't that install dependencies automatically? In fact I did have dash installed, but it looks like an older version. I had to manually reinstall and now it works. I don't know how this could have happened.

Aha. We wouldn't have specified as a dependency the specific Dash version that introduced -find: we'd just have used the latest stable release version. If you're going to use MELPA, it's recommended practice to routinely update packages.
