traceback w/3.0 on M1 macbook

[manaslupisani]

In light of the announcement of hb 3.0: https://brew.sh/2021/02/05/homebrew-3.0.0/ I tried a fresh install on a new M1 laptop. Off the bat, I'm getting a traceback from Ruby? Anyone else encountered this? What's the fix?

You have stuff in /Library/Ruby/Gems/2.6.0/gems/ that shouldn't be there. Mine has:

bundler-1.17.2/
did_you_mean-1.3.0/
irb-1.0.0/
minitest-5.11.3/
net-telnet-0.2.0/
power_assert-1.1.3/
rake-12.3.2/
rdoc-6.1.0/
test-unit-3.2.9/
xmlrpc-0.3.0/

I'd suggest moving or deleting the rest (e.g. bigdecimal-3.0.0)

That did it. Thanks a bunch, Mike.

You're very welcome.
