helloword项目真机调试、编译能通过，archive时报错
/Applications/CocosCreator3.app/Contents/Resources/cocos2d-x/build/cocos2d_libs.xcodeproj The linked library ‘libv8_monolith.a’ is missing one or more architectures required by this target: armv7.
通过论坛帖子替换libv8_monolith.a或者去掉build settings–VALID_ARCHS 里的 armv7依旧报错，编译不通过
去掉build settings–VALID_ARCHS 里的 armv7后也clean build folder了 点击archive依旧报如上错误，我看论坛里有人成功了，是我那个步骤错了吗？求教
