An error occurred while installing hpricot (0.8.6), and Bundler cannot
continue.

In Gemfile:
  ronn was resolved to 0.7.3, which depends on
    hpricot
Error: failed to run `/opt/homebrew/Library/Homebrew/vendor/bundle/ruby/3.1.0/bin/bundle install`!

What should I do?

Might be an incompatibility with Xcode/CLT 15.3. I haven't tested 15.3 yet, but will give it a try when I can.

I found out that this is clang's new error since clang 16. I have no idea why this is happening in Xcode 15.3's CLT. Maybe Apple merged some clang 16's code.

FreeBSD had the same problem about 10 months ago, and they solved by patching hpricot.
