【问题描述】：
在启动命令 npm run eject 后，我按照以下步骤操作：
- Bare：我想要一个 React Native 项目。
- 我设置了应用和xcode项目的名称
命令返回此消息Ejected successfully!
之后，进入ios生成的文件夹，我运行命令pod install，结果是Pod installation complete!
执行此过程后，我尝试使用ios 模拟器运行应用程序，但出现此错误：
Expo SDK 需要 Expo 才能运行。似乎本机 Expo 模块不可用，并且此代码未在 Expo 上运行。访问https://docs.expo.io，了解有关开发世博项目的更多信息。
请注意，在执行npm run eject 命令之前，应用程序正常运行。
这是eject之前的package.json：
{
"main": "node_modules/expo/AppEntry.js",
"scripts": {
"start": "expo start",
"android": "expo start --android",
"ios": "expo start --ios",

eject 之后，package.json 变为：

【问题讨论】：
-
你打算如何运行你的项目？
-
@Andrew 我使用以下命令启动项目：
npm run ios -
您是否尝试过通过 Xcode 构建应用程序？
-
@Andrew 是的，但是结果是一样的
