An in-range update of mock-fs is breaking the build 🚨

[greenkeeper]

Version 4.4.1 of mock-fs just got published.

Branch	Build failing 🚨
Dependency	mock-fs
Current Version	4.4.0
Type	dependency

This version is covered by your current version range and after updating it in your project the build failed.

mock-fs is a direct dependency of this project this is very likely breaking your project right now. If other packages depend on you it’s very likely also breaking them.
I recommend you give this issue a very high priority. I’m sure you can resolve this 💪
