無法安裝cocoapods，報告pod設置

Question

我正在按照本教程http://www.raywenderlich.com/64546/introduction-to-cocoapods-2在我的MacBook上安裝cocoapods （Mavericks 10.9.5）。

我已成功使用此命令

sudo gem update --system
sudo gem install cocoapods

但是每當我使用pod setup我都會得到這個日志

如果我輸入pod install也會出現。

我該怎么辦？ 提前致謝

Answer 1

最新版本的cocoapods gem（v0.34.2）需要xcodeproj gem> = 0.19.2的版本。 但最新版本的xcodeproj gem（0.19.3）導致了這個問題。

管理通過將xcodeproj版本修復為0.19.2來解決此問題。

gem uninstall xcodeproj
gem install xcodeproj -v 0.19.2

或者在gemfile中指定gem 'xcodeproj', '0.19.2' ，然后運行bundle。
