I have the same issue; seems to impact all dev environments on OSX — @tgxworld made some changes in the past 24 hours that may have broken things?
I think specifically
https://github.com/discourse/mini_suffix/commit/129964864513eef36c675cdd709ffcd9075437be
OSX doesn’t like the .so filetype
Not sure if anyone else on the @team has any ideas, or if we’ll just wait for @tgxworld (it’s 4am in his time zone, so I assume he’s asleep)
