How to resolve ember cli problems when the issue appears to reside in a plugin from node_module?

I am running into this problem when running ember scripts

The plugin {"_parallelBabel":{"requireFile":"./node_modules/ember-cli-htmlbars-inline-precompile/lib/require-from-worker","buildUsing":"build","params":{"templateCompilerPath":"./bower_components/ember/ember-template-compiler","parallelConfig":[]}}} didn't export a Plugin instance

What is the problem ember-cli is running into here? What would be a good strategy for debugging these type of problems?
