I’ve linked a package that is outside of the project by first running
npm link in the outside package, then
npm link name-of-package inside the project.
I am now getting this error:
Module build failed: ReferenceError: Unknown plugin "transform-es2015-arrow-functions" specified in "base" at 0, attempted to resolve relative to "/path/to/location/far/away/from/project/name-of-package"
Of course there’s no babel plugin there.
