由于本机基本模块，Expo for Web无法编译

Question

我正在尝试为托管的expo项目工作的“ web博览会”部分。

我将托管的expo项目升级到了expo sdk 33，以便我也可以在Web平台上部署我的应用程序，并且理想情况下可以将其从Firebase托管。我遵循了博览会的官方指示：

升级Expo SDK演练

Expo CLI和SDK Web支持Beta

在Expo init项目中使用Expo for Web

有关如何升级到SDK 33以及如何配置和启用Web平台的信息。

Expo-cli版本为：“ 2.19.5”

我正在使用纱线

package.json

{
  "main": "node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "eject": "expo eject"
  },
  "dependencies": {

  },
  "prettier": {
    "jsxBracketSameLine": true,
    "arrowParens": "always",
    "bracketSpacing": false
  },
  "private": true
}

这是我遇到的错误，对不起，我不确定如何解决。我已经将expo和native base更新到了最新版本。

任何帮助将不胜感激。

这是因为世博会CLI使用的WebPack配置将自动transpile任何node_modules与开始expo，react-native，react-navigation，@expo，@react-navigation。任何其他模块都需要通过创建扩展的新webpack配置@expo/webpack-config或通过将模块名称添加到app.json类似文件来手动添加到配置文件中，例如：https : //github.com/hectahertz/react-native-typography/pull/ 31

"expo": {
  ...
  "web": {
    "build": {
      "babel": {
        "include": [
          "native-base-shoutem-theme"
        ]
      }
    }
  }
