RubyMotion错误:工具“xcodebuild”需要Xcode

Question

我使用以下方法创建了一个新的RubyMotion项目：

motion create NewMotion

然后我安装了相关的包：

bundle install

现在，每当我运行该应用程序时，我都会得到一个错误：

➜  NewMotion  rake
/Users/info/.rvm/gems/ruby-2.0.0-p353/gems/bundler-1.6.2/lib/bundler/runtime.rb:222: warning: Insecure world writable dir /usr/local in PATH, mode 040777

请注意，我使用的是Rubyruby2.0.0p353。

任何帮助都将不胜感激。

干杯

好吧，看来我知道我是怎么解决这个问题的：

• 从developer.apple.com安装Xcode
• 点Xcode -选择Xcode开发人员目录 sudo选择-switch /Applications/Xcode.app/Contents/Developer
