What should be changed?

Been getting the following error on the last 4-5 labs or so.
Didn't know if it was an issue on my computer of what the labs are requiring is outdated.

Your bundle is locked to mimemagic (0.3.3) from rubygems repository
https://rubygems.org/ or installed locally, but that version can no longer be
found in that source. That means the author of mimemagic (0.3.3) has removed
it. You'll need to update your bundle to a version other than mimemagic (0.3.3)
that hasn't been removed in order to install.
