Uninstalling all gems Ruby 2.0.0

Question

It seems that ruby 2.0.0 has added \"default\" gems to the mix and makes them non removable by gem uninstall.

How can you remove all non default gems?

Answer 1

I used this one line script.

for i in `gem list --no-versions`; do gem uninstall -aIx $i; done

It ignores default gem errors and just proceeds. Simple and self-evident.
