Cocoapods install in Mac

First, check the version of Ruby you are using.

$ruby -v ruby 

2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-darwin18] 

$ which ruby 

usr/bin/ruby


Now use Homebrew to install the latest Ruby.

$ brew install ruby 

==> 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:

$ echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> /Users/xxx/.bash_profile
(For newer mac the file name will be : .zprofile )


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. Now you will go to see the installed Ruby. Make sure to replace the 'xxx' with your username.

$ echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> /Users/xxx/.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
(For newer mac the file name will be : .zprofile )

Finally, Make sure your PATH is in place.

$ ruby -v ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-darwin18] 

$ which ruby 

/usr/local/opt/ruby/bin/ruby


You're good to go! Make sure you install by specifying the save destination as follows.

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