Ruby bundle install fail

Question

My system is macOS m1 chip. I'm using ruby to bundle install from gemfile, but it seems like the llhttp-ffi gem has conflict, I'm not really sure about the problem. So below is the output when I tried bundle install. I've tried to search about Failed to build gem native extension or just gem install ffi, both have not worked.

An error occurred while installing llhttp-ffi (0.4.0), and Bundler cannot continue.
Make sure that `gem install llhttp-ffi -v '0.4.0' --source 'https://rubygems.org/'` succeeds before bundling.

In Gemfile:
  http was resolved to 5.0.4, which depends on

Answer 1

I was seeing the same problem while updating Ruby from 2.7.5 to 2.7.6. Big Sur 11.6.1, Intel i7, fwiw.

After many confusing errors and failed solutions, I deleted my entire bundle/vendor directory and bundled anew. This got me a clean bundle install.

I'm not sure what the conflict was, but a clean slate fixed it.
