Expo - React Native - Metro 配置文件

Question

我正在使用 React Native 并使用 Expo CLI 构建一个应用程序。一旦应用程序构建并在试飞中进行测试，我就会遇到资产丢失的问题。我收到以下错误。我已经阅读了有关 React Native 和 Expo 的文档，但似乎无法找出问题所在。还附上了我的 app.json 和 Metro.config.js 文件。

It looks like that you are using a custom metro.config.js that does not extend @expo/metro-config.
This can result in unexpected and hard to debug issues, like missing assets in the production bundle.
We recommend you to abort, fix the metro.config.js, and try again.

Answer 1

我终于找到了答案，我必须添加变压器和assetPlugins。

 transformer: {
      assetPlugins: ['expo-asset/tools/hashAssetFiles'],
    },
