不能让CocoaPods工作

Question

我安装了CocoaPods,它说Successfully installed cocoapods-0.33.1,但无论我试图用pod命令做什么,比如pod install,我得到以下控制台输出:

Max$ pod install

我使用的是Mac OS 10.10(Yosemite beta版)和Xcode 6.0 beta2,但我回想起当我使用Mavericks和Xcode 5.1.1时,我遇到了同样的问题.

Answer 1

我终于解决了我的问题.

简短回答:

我不得不安装ruby 2.1.2,然后重新安装cocoapods,一切正常.

答案很长:

1. 解决所有警告brew doctor;
   • 删除未使用的库;
   • 删除MacPorts;
   • 解决我已经不记得的其他警告;
   • 我甚至可以重新安装brew.
2. 安装rvm;
3. 使用rvm安装并使用ruby 2.1.2;
   • rvm requirements 抱怨许多丢失的包裹,安装它们;
   • 其中,有gcc46,我无法安装.在Xcode 4.2之后,命令行工具没有gcc.所以如果rvm requirements找不到,那就建议gcc46.但重点是,安装brew install apple-gcc42解决了这个问题.rvm requirements停止抱怨,你可以安装ruby 2.1.2:
   • rvm install 2.1.2;
   • rvm use 2.1.2;
4. 按照@Varsha Vijayvargiya的回答中的建议安装cocoapods .

我可能会忘记一些事情,所以如果你有任何问题 - 请问.以下是一些帮助我的链接:

• 将mac osx更新为10.10并且pod无法正常工作 ;
• 在Mac OS X 10.8 Mountain Lion上安装带有RVM和Homebrew的Ruby 2.0.0 ;
• Homebrew GCC不会安装在带Xcode 6的OS X 10.10 Yosemite上 ;
• 在小牛队上安装gcc.
