Error message keep popping out when using terminal

Error message keep popping out when using terminal


Whenever I use terminal to do a certain task, for example,
brew cask install vscodium or bundle show minima (jekyll)
my terminal keeps telling me this:

Ignoring commonmarker-0.17.13 because its extensions are not built. Try: gem pristine commonmarker --version 0.17.13

What do I need to update to get rid of this error message?


Just to be sure, do you already have brew installed? (



also here are some of the stuff I tried but failed.


and have you tried using the alternate installation method?

Add this line to your application’s Gemfile:

gem 'commonmarker'

And then execute:

$ bundle


I think it worked.

Here is the message I got:
