Ruby 1.9.3.在做的过程中,我刚刚下载了xcode 4.5.2来取代4.3.2.但是当我这样做时,我得到以下错误.我该如何解决这个问题？
提前致谢.
The operation can’t be completed because some items had to be skipped. For each item,choose File > Get Info,make sure “Locked” is deselected,and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access,try again.
