Description

when running a pod command such as pod install, there are no warnings. however if you run bundle exec pod install then it shows a console warning:

Your RubyGems version (3.0.3.1) has a bug that prevents required_ruby_version from working for Bundler. Any scripts that use gem install bundler will break as soon as Bundler drops support for your Ruby version. Please upgrade RubyGems to avoid future breakage and silence this warning by running gem update --system 3.2.3

happens on 0.70.8. i also tried creating a brand new project running the newest 0.71.6 version and its the same result.

its required/better to run bundle exec pod install instead of just pod install, otherwise it may not use your projects version of CocoaPods when downloading pods.

Hi @Adnan-Bacic, thanks for the question.
I think that this is a issue with the local setup. As the error is mentioning: Your RubyGems version (3.0.3.1) has a bug....

Have you tried to update it as suggested by using gem update --system 3.2.3 to see if it fixes the problem?

i assumed this was related to some sort of react-native versioning.

i tried running the command. but i started getting a lot of errors.

when running bundle install:

/Library/Ruby/Site/2.6.0/rubygems.rb:263:in `find_spec_for_exe': can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException)
        from /Library/Ruby/Site/2.6.0/rubygems.rb:282:in `activate_bin_path'
        from /usr/local/bin/bundle:23:in `<main>'

gem install bundler:

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/gems/2.6.0 directory.

the most simple and straightforward solution was to just run rbenv local 2.6.10 or rbenv local 2.7.5, this will add back the .ruby-version file which was previously added and then removed. this saves me having to follow other complicated guides.

before adding the .ruby-version file, rbenv version returns system, which is 2.6.10 according to ruby -v.

im not sure what the exact problem is. i see the error messages refer to version 2.6.0, while my system ruby version is 2.6.10.

either way, the local .ruby-version file with a version number seems to fix the error. i can run gem install bundler, bundle install and bundle exec pod install again without errors.

Happy that you found a solution that works for you. I think that there is something wanky going on with the local Ruby setup, but it should not be React Native specifically as it doesn't enforce any Ruby version anymore! ;)

This steps work for me perfectly to create react native project without error
1- npx react-native init testproject --skip-install -—npm
2- cd testproject
3- npm install or yearn install
4- cd ios
5- bundle config --local build.ffi --with-cflags=-Wno-error=implicit-function-declaration
6- bundle install
7- bundle exec pod install

Have you tried upgrading RubyGems as the warning suggested?
