It comes to error when installing cocoapods on MacOS(M1 chip). I ran the command sudo gem install cocoapods and got the following errors.

ERROR:  While executing gem ... (Gem::FilePermissionError)

    /usr/bin/gem:21:in `<main>'

Expectation: the pod command is correct to install and setup.

After many searches on Apple Develop forum and I found that one solution is helpful so I sticked the code here.

Step 1: Install homebrew

$ curl -fsSL -o install.sh https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh
$ /bin/bash install.sh

Step 2: brew install chruby ruby-install

Step 3: brew install cocoapods

Step 4: brew upgrade cocoapods

Now you can use pod install on your iOS project.

From what I found online is that this issue is caused due to Mac OS default installation of Ruby and it is old version. You would have to update it using home-brew

step 1: Install Homebrew /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

step 2: Install Ruby Manager brew install ruby-install chruby

step 3: add this to your zsh profile source /usr/local/opt/chruby/share/chruby/chruby.sh and source /usr/local/opt/chruby/share/chruby/auto.sh

step 4: save it

step 5: write ruby-install --latest ruby to install latest ruby version

step 6: restart terminal and check if new version has been installed ruby --version

step 7: finally sudo gem install cocoapods

if you are unable to follow these instruction then please follow this video: https://www.youtube.com/watch?v=uZD2EQbBqPg
