Cannot create Rails App - gem issues "Ignoring nokogiri" and other gems
When I try to create a new Rails App it fails. I am on Big Sur 11.3, Ruby 2.7.2, and when type rails-v shows 6.0.3.4 but also ignoring quite a few gems including nokogiri and 6-7 others. I have tried to move to Ruby 3+ by updating rbenv and several other approaches however just can't get to Ruby 3 even as an option. I am guessing there is mismatch between Ruby version and Rails version but not sure. Tried to update bundle, or gem pristine none of that worked.
When I create a new Rails App it seems to create the files but throws quite a few errors re gemfiles can't locate. Here is a sample let me know if this helps:
Ignoring nokogiri-1.10.10 because its extensions are not built. Try: gem pristine nokogiri --version 1.10.10
Could not find gem 'rails (~> 6.0.3, >= 6.0.3.4)' in any of the gem sources listed in your Gemfile.
Run bundle install to install missing gems.
ryanmindigo@Ryans-MacBook-Air-2 Rails-Apps % bundle install
Could not locate Gemfile
Then when I try to run the server with Rails S get similar issue:
Ignoring nokogiri-1.10.10 because its extensions are not built. Try: gem pristine nokogiri --version 1.10.10
Could not find gem 'rails (~> 6.0.3, >= 6.0.3.4)' in any of the gem sources listed in your Gemfile.
Run bundle install to install missing gems.
Here is the full dump of what happens:

run bundle install
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java.

It sounds as if you want to be current. So you might focus on getting Rails 7 and Ruby 3 installed. 'nokogiri' has frequently caused me issues like this—I never quite know what got it working again. Search for how to install Rails using rbenv. I don't use rbenv but it seems to be the most commonly used so should be solid. Good luck.
One old set of notes said these two commands worked.
brew install libxml2
bundle config build.nokogiri --use-system-libraries --with-xml2-include=/usr/include/libxml2/
Thanks Greg! You are prob right, I did spend 30mins trying to get to Ruby 3+ and Rails 7 but for some reason couldnt get to Ruby 3. Will try those commands next :)
