You have to install development tools first.@andesappal Could you check if you have XCode Command Line Tools installed? by runningxcode-select --installHere’s what I did, this might help you @mareFernando03 :
mkmf.logfile mentioned in the output from the failedffiinstallation. For me, this was at/Library/Ruby/Gems/2.6.0/extensions/universal-darwin-21/2.6.0/ffi-1.15.5/mkmf.log.xcrun clangcommand, nearby the-Iparameter. For me this is/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.1.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin21universal-darwinXXdirectory to see what files you have in there (orcd/ls). For me, I could see that I have a directory nameduniversal-darwin22and none nameduniversal-darwin21as mentioned in themkmf.log./Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.1.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin21in my case), and symlink it to the correct path (in my case/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.1.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin22)ffiagain and it should work. For me, I used this command:arch -x86_64 sudo gem install ffiI hope this can help some people.
It seems that the build script is using the wrong include directory - universal-darwin19 instead of universal-darwin20. Creating a link for that directory fixed the issue for me.
Mac M1 you need run this command:
sudo arch -arm64 gem install ffiIf you encounter the error “An error occurred while installing ffi (1.15.5), and Bundler cannot continue” while running the command npx react-native@latest init AwesomeProject, try initializing your project in a folder directory without spaces. For example, run npx react-native init on the “Desktop” directory, which usually doesn’t have spaces in its path. This should resolve the issue.
Having the same issue. Adding the symlink did not work. I was just reading this issue and OP hinted at removing spaces in the build path.
Removing the space in the pathname solved my issue.
Disclaimer !! You have to be careful with the next decisions
I was actually getting an error even after doing that, then I had to install another version of ruby using home brew.
brew install rubyFor M1, M2
echo 'export PATH="/opt/homebrew/opt/ruby/bin:/opt/homebrew/lib/ruby/gems/3.2.0/bin:$PATH"' >> ~/.zshrcFor Intel
echo 'export PATH="/usr/local/opt/ruby/bin:/usr/local/lib/ruby/gems/3.2.0/bin:$PATH"' >> ~/.zshrcThe 3.2.0 in the command above assumes Homebrew installed a Ruby version that starts with 3.2. If it installed a different version, replace 3.2 with the first two digits of your Ruby version.
Then “refresh” your shell for these changes to take effect:
source ~/.zshrcOr you can open a new terminal tab, or quit and restart Terminal.
Replace .zshrc with .bash_profile if you are using Bash. If you’re not sure, read my guide to find out which shell you’re using.
To check that you’re now using the non-system version of Ruby, you can run the following commands:
which rubyIt should not be
/usr/bin/rubyruby -vIt should be 3.2.+ or later.
Once you have this new version of Ruby installed, you can now install bundler (or any other gem):
I then install cocoa pod
sudo gem install cocoapodsand everything has been okay since then .

This works, I got confused on last 4th point, so adding it
sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX14.0.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin23 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX14.0.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin22Ran into this same issue. Here’s how I fixed mine.
In your
mkmf.log, you would find the universal-darwinxx file you should have. In my case, it was/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX13.1.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin21Run this command
cd $(xcode-select -p)/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0to confirm what files you currently have. I found that I had universal-darwin22After you have confirmed that you have a different file, run this command
sudo ln -sf universal-darwin22 universal-darwin21. This command creates a symbolic link nameduniversal-darwin21that points touniversal-darwin22.This should fix the issue
I have a user who ran into this issue today on his Mac M1 based computer. The only steps that were required to fix this were running xcode-select --install and bundle install again.
You might get
Operation not permittedusing this, it’s best to usesudo ln -s /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin23 /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/include/ruby-2.6.0/universal-darwin22Thanks! In my case it was creating a link universal-darwin21 which directs to universal-darwin22
Same error on Catalina. Development tools are already installed.
