Unknown command 'string split : -- strika/catfish-pine:.'

I get this error when I try to use Fundle on Ubuntu 16.04. This setup works just fine on Ubuntu 18.04. Is there a dependency that's missing? Thank you.

I resolved the issue by using Fish from the ppa. I assume that Fundle requires a certain version of Fish. Maybe it would be nice to add that to README.

Thank you.
