Unknown plugin “external-helpers” specified in “base” at 0, what does this even mean?












1















I'm building a glimmerjs application like this:



ember build --environment test


And the error is:



Build failed.
Build Error (RollupWithDependencies)

Unknown plugin "external-helpers" specified in "base" at 0, attempted to resolve relative to "/Users/givanse/code/pretender"

Stack Trace and Error Report: /var/folders/6y/8lyh7xn954v714ktlj5nmndw0000gn/T/error.dump.099d52a5b4b21a993722a86f9f2693ec.log


In the log:



nodeAnnotation: RollupWithDependencies                                                                                
- nodeName: RollupWithDependencies
- originalErrorMessage: Unknown plugin "external-helpers" specified in "base" at 0, attempted to resolve relative to "/Users/givanse/code/pretender"
- stack: Error: Unknown plugin "external-helpers" specified in "base" at 0, attempted to resolve relative to "/Users/givanse/code/pretender"
at error (/Users/givanse/code/project-pulse/node_modules/rollup/dist/rollup.js:170:12)
at /Users/givanse/code/project-pulse/node_modules/rollup/dist/rollup.js:8937:6
at <anonymous>


That stack trace corresponds to the transform function here rollup/blob/v0.41.6/src/utils/transform.js#L95



Adding some logging there shows that the error happens when babel.transform is invoked.



Posting not hoping for an answer, but just a clue or theory.
