Elm: Multiple modules named maybe

I'm running through a tutorial, and I'm trying to import the Maybe module, but am getting the below error:

I found multiple modules named 'Maybe'.

Module 'Main' is trying to import it.

Modules with that name were found in the following locations:

directory ././Maybe.elm
package elm-lang/core

How do I point at one of the above packages?

Solution

  • The Maybe module from the elm-lang/core package is imported by default, so if that's what you're trying to import, there's no need to do so.

    I can't be sure what is causing the name collision without seeing which packages you have installed, but if you've created your own module called Maybe, I suggest renaming it. Module name patterns such as NameOfDirectory.NameOfModule are common in Elm (in fact, I think they're somewhat enforced).
