我用coco pod安装了'Mantle'.但是当我尝试在我的模型中使用它时,它就会出现这个错误.
/Users/bgbb/Developer/experimental/MantleTest/MantleTest/TestMTL.h:11:32:找不到'MTLJSONSerializing'的协议声明
#import "MTLModel.h"
@interface TestMTL : MTLModel <MTLJSONSerializing>
@end
这是我的podfile.
platform :ios, '7.0'
pod 'Mantle', '1.1.2'
我不确定我错过了什么.任何线索？
它在几天前工作,但今天创建一个新的vertualenv导致这种失败.
分别尝试安装python-setuptools也遇到了同样的问题.它在Mac OS上.
