React 原生语义问题：重新定义"方法描述符"

Question

应用程序react原生应用程序在模拟器上编译得很好，但当我试图从xcode在iphone上运行它时，我会收到以下错误：

语义问题：

1-"MethodDescriptor"的重新定义-包含在路径/rect native/RectCommon/cxrect/ModuleRegistry.cpp:10:中的文件中

2-"NativeModule"的重新定义-1。在react-path/nature/RectCommon/cxrreact/ModuleRegistry.cpp:10:中包含的文件中

精细React cxxrreact/NativeModule.h 上的代码

namespace facebook {
namespace react {
struct MethodDescriptor {
std::string name;
// type is one of js MessageQueue.MethodTypes
std::string type;
MethodDescriptor(std::string n, std::string t)
: name(std::move(n))
, type(std::move(t)) {}
};
using MethodCallResult = folly::Optional<folly::dynamic>;
class NativeModule {
public:
virtual ~NativeModule() {}
virtual std::string getName() = 0;
virtual std::vector<MethodDescriptor> getMethods() = 0;
virtual folly::dynamic getConstants() = 0;
virtual void invoke(unsigned int reactMethodId, folly::dynamic&& params, int callId) = 0;
virtual MethodCallResult callSerializableNativeHook(unsigned int reactMethodId, folly::dynamic&& args) = 0;
};

我通过终端执行"pod install"命令，然后在Xcode中清理和重建我的项目，解决了这个问题。
