This month, I got a MacBook Pro early 2015 at a store for 10,000 yen. (The battery was inflated, so I repaired it for 20,000 yen. The keyboard, trackpad, and battery are new.)
I love Apple so I was impressed with it.
So I started learning Swift, which I wanted to study when I got a Mac someday. I left it here because I stumbled a little while installing Cocoapods for learning.
CocoaPods is a dependency manager for Swift and Objective-C Cocoa projects. It has over 79 thousand libraries and is used in over 3 million apps. CocoaPods can help you scale your projects elegantly. Cocoapods Official Website
When translated
CocoaPods is a dependency manager for Swift and Objective-C Cocoa projects. It has over 79,000 libraries and is used by over 3 million apps. CocoaPods help you scale your project elegantly.
In other words, it's a library management tool for iOS. If you don't use Cocoapods, you'll have to get and install all the libraries yourself.
Cocoapods are installed using gems. (Mac comes with Ruby from the beginning)
Cocoapods installation
sudo gem install cocoa pods
Cocoapods setup
pod setup
However, I got an error like this during the installation.
ERROR: Error installing cocoapods:
ERROR: Failed to build gem native extension.
Apparently, the reason is that the version of Ruby that comes with the Mac from the beginning does not support Cocoapods. The Ruby version of Catalina was 2.6.3.
There are two solutions (maybe) ・ Raise the version of Ruby ・ Lower the installed version of Cocoapods
This time, it was supported by raising the version of Rubu.
After investigating, it seems that Ruby is upgraded by using a version control tool called rbenv.
We have upgraded the version by referring to this article. How to upgrade Ruby on Mac terminal
After that, install and set up according to the flow introduced in the installation procedure, and you're done.
This time, I introduced the Cocoapods installation procedure and the Ruby version upgrade method required for it.
Currently, I am studying Swift using books and Udemy as a hobby. I can make Apple Watch, iPad, and Mac apps as well as iOS apps, so I would like to continue studying.
that's all
