[mraesener-aubex]

Hey everybody, I've just installed elm on my mac and following the docs. after starting elm reactor and then opening src/Main.elm I run into the following:

❯ elm reactor
Go to http://localhost:8000 to see your project dashboard.

我有类似的问题，这真让人困惑

elm make src/Main.elm                           
Success!     

-- ERROR -----------------------------------------------------------------------

I ran into something that bypassed the normal error reporting process! I
extracted whatever information I could from the internal error:

>   Map.!: given key is not an element in the map
>   CallStack (from HasCallStack):
>     error, called at ./Data/Map/Internal.hs:610:17 in containers-0.5.11.0-FmkfE5FIiXiCSIJBVRC1nU:Data.Map.Internal

These errors are usually pretty confusing, so start by asking around on one of
forums listed at https://elm-lang.org/community to see if anyone can get you
unstuck quickly.

-- REQUEST ---------------------------------------------------------------------

If you are feeling up to it, please try to get your code down to the smallest
version that still triggers this message. Ideally in a single Main.elm and
elm.json file.

From there open a NEW issue at https://github.com/elm/compiler/issues with your
reduced example pasted in directly. (Not a link to a repo or gist!) Do not worry
about if someone else saw something similar. More examples is better!

This kind of error is usually tied up in larger architectural choices that are
hard to change, so even when we have a couple good examples, it can take some
time to resolve in a solid way.elm: Map.!: given key is not an element in the map
CallStack (from HasCallStack):
  error, called at ./Data/Map/Internal.hs:610:17 in containers-0.5.11.0-FmkfE5FIiXiCSIJBVRC1nU:Data.Map.Internal
