除非没有其他选择，否则您不应该手动删除文件夹.您应该先尝试运行卸载脚本:

You shouldn't manually delete a folder unless there is no other option. You should try running the uninstall script first:

sudo python /Developer/Tools/uninstall-qt.py

如果您运行的是最新的Xcode应用程序包，而不是默认的Snow Leopard/Lion Xcode，则此脚本的路径将有所不同.

The path to this script will be different if you are running the latest Xcode app bundle and not the default Snow Leopard/Lion Xcode.
