未安装'expo' / 'react-native' / 'react-native-render-html' / 'react-navigation'依赖项

watchman watch-del-all && rm -rf node_modules/ && yarn cache clean && yarn install

我尝试了很多次重新安装这些依赖项，但每次运行时都是如此

exp start -c

我有以下警告

01:22:43 [exp] Warning: 'expo' dependency is not installed.
01:22:43 [exp] Warning: 'react-native' dependency is not installed.
01:22:43 [exp] Warning: 'react-native-render-html' dependency is not installed.

这是我的package.json

我的项目已经推出了世博会套件，我正在按照弹出屏幕的说明进行操作 . 在弹射之前它工作正常，但现在我不能让我的代码运行 .

我在Xcode中构建我的代码并且它成功了 . 我可以运行模拟器，但我什么都看不到它，只是白色的屏幕 . 期待我底部有一个红色的 Banner ，上面有“解除”“重新加载”“复制”“更多信息” . 我尝试复制，但没有任何东西进入我的剪贴板 .

我弹出的回购是：1 . npm run eject 2.选择expoKit 3.等待它弹出4.更新expo sdk到26 5.更改本地响应expo fork 6. pod install

我错过了什么？
