Cause

gem update

gem install cocoapods

It is considered that the above two are clearly not going well

Only solve the solution

Please execute the following commands in order

sudo gem update –system -n /usr/local/bin

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

pod setup

Brief explanation

cocoapods is running with ruby so we need gem to manage ruby

If you normally update gem it will result in a permission error with rootless function

sudo gem update –system -n /usr/local/bin

By specifying this location by executing it in / usr / local / bin like this

After updating gem, put cocoapds in the latest gem

Because we can not do it routinely with the route-less function

Specify the place to install as follows

Try not to be affected by route-less

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

Preparation is complete. You can run pod setup
