macos - Unity detects wrong ruby versions and cannot install cocoapods

Unity 2021.3.45f

IOS Resolver tries to install cocoapods. I have updated ruby version to 3.4.0, but Unity keeps to searching for 2.6.0. How to fix it?

Path:

export PATH="$HOME/.gem/ruby/3.4.0/bin:$PATH"

export GEM_HOME="$HOME/.gem"
export GEM_PATH="$HOME/.gem"
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8

IOS Resolver:

gem install cocoapods --user-install' failed with code (1):

Would highly recommend a ruby version manager, rvm, rbenv, asdf, chruby, etc. This will make managing ruby versions and installing ruby dependent gems and libraries much easier in the future. – engineersmnky Commented Feb 17 at 15:03

I have used zsh. Looks like Unity uses bash. In terminal, Settings / General / Shells open with change to bin/bash. Quit and restart terminal. gem install cocoapods, gem install drb -v 2.0.6, gem install activesupport -v 6.1.7.8, gem install cocoapods. Open Unity, get successful build.xx
