现象

• 通过 npm create创建一个新的项目可以成功显示在 ios app上面，但是在运行 project文件夹下自带的demo时候，报错log如下：

error: bundling failed: Error: Unable to resolve modulereact-native-root-toastfrom/Users/mac/Desktop/ReactNativeDemo/miot-plugin-sdk/projects/com.xiaomi.demo/Main/UIComponent/ToastExample.js`: Module does not exist in the module map This might be related to https://github.com/facebook/react-native/issues/4968 To resolve try the following:

1. Clear watchman watches: watchman watch-del-all.
2. Delete the node_modules folder: rm -rf node_modules && npm install.
3. Reset Metro Bundler cache: rm -rf /tmp/metro-bundler-cache-* or npm start -- --reset-cache. 4.

期望（必填） 我只想跑起来这个 com.xiaomo.demo这个工程，观看预览。

其他的上下文/日志/截图

尝试过的解决办法 不知道如何解决

我也遇到了同样的错误，Android上运行米家demo会报错，iOS没问题。10012版本。期望能解决一下。好像和ToastExample有关。

在com.xiaomi.demo下，执行npm install后，重新npm start即可
