how can I do to install pod on my mac?

Answer 1

I faced a similar issue, by default system ruby version is being used, we need to bypass it and then continue with cocoa pods.

Install ruby using homebrew

brew install ruby

By default, binaries installed by gem will be placed into: /usr/local/lib/ruby/gems/2.7.0/bin

You may want to add this to your PATH.

ruby is keg-only, which means it was not symlinked into /usr/local, because macOS already provides this software and installing another version in parallel can cause all kinds of trouble.

If you need to have ruby first in your PATH run (and replace user_name with your username):

echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> /Users/user_name/.bash_profile

For compilers to find ruby you may need to set:

 export LDFLAGS="-L/usr/local/opt/ruby/lib"
 export CPPFLAGS="-I/usr/local/opt/ruby/include"

Follow the instructions to set PATH. Replace user_name with your username

echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> /Users/user_name/.bash_profile
echo 'export LDFLAGS="-L/usr/local/opt/ruby/lib"' >> ~/.bash_profile
echo 'export CPPFLAGS="-I/usr/local/opt/ruby/include"' >> ~/.bash_profile

source ~/.bash_profile

Check your path

ruby -v
ruby 3.1.1p18 (2022-02-18 revision 53f5fc4236) [x86_64-darwin20]
user@MacBook-Air ios % which ruby
/usr/local/opt/ruby/bin/ruby

That's it, ruby version is all set Install cocoa pods then you are good to go

sudo gem install -n /usr/local/bin cocoapods

Answer 2

just try reinstalling the missing gem minitest mentioned in that error message like this:

gem install minitest -v 5.1.0

this should solve your current problem but you may have more errors for other missing gems. in that case, check your message for things like Could not find 'minitest' (>= 5.1) and try installing them.

if you are overwhelmed by too many of these missing gem errors, try uninstalling cocopods and then re-installing it.
