unable to use cocoapods after updating

Question

I have updates Ruby , Gems and Cocoapods on my mac OSX 10.9.5, after the update I am unable to execute the command

pod install

I'm getting the below error from terminal

/Library/Ruby/Gems/2.0.0/gems/cocoapods-0.34.2/lib/cocoapods/user_interface/error_report.rb:13:in `report': incompatible character encodings: UTF-8 and ASCII-8BIT (Encoding::CompatibilityError)

    from /usr/bin/pod:23:in `load'
    from /usr/bin/pod:23:in `<main>'

I have created a Podfile with the below content

platform :ios, ‘7.1’

pod 'AFNetworking', '~> 1.3.3’

Cocoapods worked perfectly before the update. any help is greatly appreciated.

Answer 1

This character " ‘ " is incomatible with cocoapods in first line. You should use this instead " ' ". So your podfile should be like this:

platform :ios, '7.1'
pod 'AFNetworking', '~> 2.4'

Answer 2

The problem was the use of incorrect quotes around the iOS version. Make sure all your quotes are ' and not ‘ or ’.
