Your Ruby version is 2.6.8, but your Gemfile specified 2.7.6 error while enabling new architecture on react-native iOS

Question

I have already gone through this post

I am facing this issue on my new react-native project version 0.71.1 while enabling the new architecture for iOS

I have done all the below steps

$ brew update
$ brew install ruby-build
$ brew install rbenv

$ rbenv install 2.7.6
$ rbenv global 2.7.6

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.zshrc
echo 'eval "$(rbenv init -)"' >> ~/.zshrc

When I run ruby --version I get ruby 2.7.6p219 (2022-04-12 revision c9c2245c0a) [x86_64-darwin22] which is the correct ruby version required to enable new architecture on iOS

but when I run bundle install && RCT_NEW_ARCH_ENABLED=1 bundle exec pod install I still get error saying

Your Ruby version is 2.6.10, but your Gemfile specified 2.7.6

What else am I missing?

I have also raised the issue in react native's GitHub repo. This might help in understanding in what I have already tried

is there a hidden file named `.ruby-version` in your project folder? — Tobias Münch, Feb 01 '23 at 13:38
yes and it has 2.7.6. It comes by default when you create a new react project and it is showing 2.7.6 — BraveEvidence, Feb 01 '23 at 13:50

I was able to resolve my issue by running bundle install --redownload. It Forces a redownload of all gems on the gemfile, assigning them to the new bundler

The Rbenv documentation can define a version file named .ruby-version inside your project folder. Perhaps you have this file with a specific version number inside.

This setting overrides your default ruby version.

Link to Rbenv-Repo: https://github.com/rbenv/rbenv

Update: After lots of suggestion, we came to the conclusion. The command bundle install --redownload updates the local bundler and everything is fine. :-)

I have correct version in .ruby-version. It is the default react-native project. I have not made any changes – BraveEvidence Feb 01 '23 at 13:49
where is your local `bundler` installed? Maybe there is a wrong reference? If the command is unknown `whereis bundler` – Tobias Münch Feb 01 '23 at 13:51
bundler: /usr/bin/bundler – BraveEvidence Feb 01 '23 at 13:52
try `rbenv exec gem install bundler` to reinstall bundler. Reference to https://stackoverflow.com/questions/33439130/bundle-uses-wrong-ruby-version – Tobias Münch Feb 01 '23 at 13:55
same issue persist – BraveEvidence Feb 01 '23 at 14:13
I have also raised this issue in react native 's GitHub repo. Please check if you have time https://github.com/facebook/react-native/issues/36002 – BraveEvidence Feb 01 '23 at 14:15
I am not very certain about package management under MacOS, but perhaps you've installed bundler as a system package. Therefore, your OS uses the system package. Another Idea is to run the bundler over `rbenv exec bundler`. Can you check both ideas? – Tobias Münch Feb 02 '23 at 08:50
Tried it same issue – BraveEvidence Feb 02 '23 at 09:26

Just change your ruby version in GemFile to 2.6.10 and then try it.

You'll find your GemFile in your project's root directory

I need that specific version of ruby to enable react native's new architecture. Also changing the ruby version can cause more unexpected bugs in the future – BraveEvidence Feb 02 '23 at 08:31

Your Ruby version is 2.6.8, but your Gemfile specified 2.7.6 error while enabling new architecture on react-native iOS
