ios - 无法安装 cocoapods，报告 pod 设置

Question

我正在学习本教程 http://www.raywenderlich.com/64546/introduction-to-cocoapods-2在我的 MacBook (Mavericks 10.9.5) 上安装 cocoapods。

我已经成功地使用了这个命令

sudo gem update --system
sudo gem install cocoapods

但是每当我使用 pod setup 时，我都会得到这个日志

    from /Users/tommy/.rvm/gems/ruby-2.1.1@msf/bin/pod:23:in `<main>'

如果我键入 pod install，它也会出现。

我该怎么办？提前致谢

最新版本的 cocoapods gem (v0.34.2) 需要 xcodeproj gem >= 0.19.2 的版本。但是最新版本的 xcodeproj gem (0.19.3) 导致了这个问题。

设法通过将 xcodeproj 版本修复为 0.19.2 来解决此问题。

gem uninstall xcodeproj
gem install xcodeproj -v 0.19.2

或在您的 gemfile 中指定 gem 'xcodeproj', '0.19.2'，然后运行 ​​bundle。
