Notes

ruby-debug-ide seems to be causing issues (on docker-compose build).

Greg's output:

...
#0 242.1 Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
#0 242.1

It is identical output on Tim's (M1).

TODO

• Fix ruby-debug-ide error
  • Replicate Greg's issue
  • Gather known solutions
    • Ruby 3.1 compatibility issue #95
    • Greg's already done the first suggestion, i.e. gem 'debase', '>=0.2.5.beta2' in Gemfile
    • The second suggestion does not seem to apply to us as we do not call bundle lock
  • Temp edit Dockerfile to do clean bundle install (not committed)
    • Gives same error
  • Revisit what Dan and Tim did for M1, was their something about platforms there that might help?
    • Merge more recent changes from main into ruby3 branch
    • Fix 2.7.0 to 3.1.2 merge failures
    • Check for failure
      • The build now works:

        …  
        curriculum-curriculum-1   | Using debase 0.2.5.beta2  
        …   
        curriculum-curriculum-1   | Using ruby-debug-ide 0.7.3  
        …
        

• Fix CircleCI error: Error response from daemon: manifest for circleci/ruby:3.1.2-node-browsers not found: manifest unknown
• Fix failing RSpec tests: 289 examples, 289 failures
  • Add SMTP gems
