Bug report

Running saber fails to compile the dev bundle

Steps to reproduce

Clone this branch: https://github.com/andreasvirkus/cottage/tree/refactor/saber git clone git@github.com:andreasvirkus/cottage.git

What is expected?

Running saber should compile the dev bundle and start up the development server.

What is actually happening?

The compiler throws an error

Other relevant information

When downgrading to 0.8.1, it runs fine (but doesn't respect the permalinks option in my config - will open up a separate issue for that).

• Result of running saber -v: 0.9.1
• Is Saber a global or local install? local install
• Which package manager did you use for the install? npm
• Does this issue occur when all plugins are disabled? yes
