I'm super new to RoR and am attempting to deploy my app on heroku. I'm getting the error you can see in the title.

I have gone through every previous question on here and tried all the solutions.
I have already tried to delete the gemfile.lock and run bundle install again to reset it. I have done various git add, commits and pushes. I'm kind of at a loss of where to go from here. Any advice would be super appreciated.

Answer 1

nokogiri (1.11.7-x86_64-darwin) is native gem for Darwin/MacOS, but Heroku run Linux so that it unable to find.
the solution is avoid-using-a-precompiled-native-gem, in your case, bundler version 2.2.+, then you'll need to run bundle config set force_ruby_platform true
you should re-check that Gemfile.lock does not contain nokogiri (1.11.7-x86_64-darwin), it should contain nokogiri (~> ...)

Answer 2

I came across the same issue on the M1 Macbook. I deleted the Gemfile.lock, then ran bundle install to re-build the Gemfile.lock and this fixed the above error.

Answer 3

Running bundle update nokogiri updated only the Nokogiri gem dependencies for me without updating the rest of the Gemfile
