我有一个可用的钛模块，但我去折射它，突然在尝试打包它时出现此错误：
Executing build.xml...
/Users/elidd1/Library/Application Support/Titanium/mobilesdk/osx/3.1.2.GA/module/android/build.xml:326: The following error occurred while executing this line:
/Users/elidd1/Library/Application Support/Titanium/mobilesdk/osx/3.1.2.GA/module/android/build.xml:281: exec returned: 2 You may need to install the Command Line Tools package through XCode, in case you haven't done so yet.
有谁知道为什么？我使用了钛内置的折射工具
