Question

Error:

Could not connect to develpment server.

Ensure the following:
- Node server is running and available on the same network - run 'npm start' from react-native root
- Node server URL is correctly set in AppDelegate

URL: http://127.0.0.1:8081/index.ios.bundle?platform=ios&dev=true

我肯定是在运行npm start。为什么不运行？

现在我看到了这个错误：

In file included from /Users/*******/f8app/node_modules/react-native-fbsdk/ios/RCTFBSDK/core/RCTFBSDKAccessToken.m:19:
/Users/*********/f8app/node_modules/react-native-fbsdk/ios/RCTFBSDK/core/RCTFBSDKAccessToken.h:21:9: fatal error:

#import <FBSDKCoreKit/FBSDKCoreKit.h>

Answer 1

项目是否在Xcode中成功？

您是否仔细检查了facebook提到的这些步骤：

确保安装了Facebook SDK框架〜/文档/ FacebookSDK。
确保FBSDK [Core，Login，Share] Kit.framework出现在链接Binary与构建目标的Build的Libraries部分相。
确保〜/ Documents / FacebookSDK在Framework Search中构建目标的构建设置的路径。（https://github.com/facebook/react-native-fbsdk）

我自己在最后一步遇到了一些麻烦，但在一个新项目重试后一切正常

如果项目构建没有成功，您可能想尝试这个。您应该首先更新现有的FBSDK（如果有的话）
