Dealing with ASSERTION Errors on pod install

Dealing with ASSERTION errors on pod install

Overview

A quick note because pod install failed to complete the installation properly.

LESSON 31 in the book walks through the CocoaPods installation steps, but I hit an error while following them exactly, so here is how I worked around it.

This kind of error is mostly environment-dependent, and technology keeps advancing day by day even while a book is being written. So rather than blaming the book, it is probably better for your peace of mind to search the official CocoaPods site, Stack Overflow, and the like for information.

Environment

• Xcode 7.2 (7C68)
• ruby 2.0.0p645
• gem 2.5.0

Commands listed in the book

Installing CocoaPods

$ sudo gem install -n /usr/local/bin cocoa pods

The error

$ pod install
[!] Unable to load a specification for the plugin `/opt/homebrew-cask/Caskroom/cocoapods/0.37.0/CocoaPods.app/Contents/Resources/bundle/lib/ruby/gems/2.2.0/gems/cocoapods-plugins-install-0.0.1`
Analyzing dependencies

CocoaPods 1.0.0.beta.1 is available.
To update use: `sudo gem install cocoapods --pre`
[!] This is a test version we'd love you to try.
