Ошибка чтения Cocoapods ~/.cocoapods/repos/master/CocoaPods-version.yml после переустановки

Я выполнил свой обычный pod update и получил следующее сообщение:

[!] There was an error reading '~/.cocoapods/repos/master/CocoaPods-version.yml'.
Please consult http://blog.cocoapods.org/Repairing-Our-Broken-Specs-Repository/ for more information.

Итак, я выполнил инструкции в http://blog.cocoapods.org/Repairing-Our-Broken-Specs-Repository/

$ sudo rm -fr ~/.cocoapods/repos/master
$ pod setup
Setting up CocoaPods master repo

Те же ошибки. Поэтому я удалил cocapods, обновил рубин и драгоценные камни, установил cocoapods:

$ sudo rm -fr ~/.cocoapods

$ sudo gem uninstall cocoapods

Просто для удовольствия я также побежал pod install.

Те же ошибки. Кто-нибудь еще сталкивается с этой проблемой? Реши это? Или посмотреть, что я делаю неправильно? Это приложение iOs уже давно использует программы. Я просто добавил pod 'ZSSRichTextEditor', '~> 0.5' в подфайл в качестве моего последнего изменения.

Update:

Вот файл CocoaPods-version.yml:

---
min: 0.32.1
last: 0.35.0
