This is caused by e-c-d depending on @ember-decorators/utils@5. The 1.0.0-beta depends on @6. Please install ember-cli-dependency-lint to catch these kinds of errors.

I think we should add a note about this to the docs. This kind of issue is happening way too often.

Ya we could also detect and issue a warning
