Expo for Web failed to compile because of native base module

问题

I'm trying to get the "expo for web" part working for my managed expo project.

I upgraded my managed expo project to expo sdk 33 so that I could also deploy my app on the web platform and ideally have it hosted from firebase. I followed official instructions from expo:

Upgrading Expo SDK Walkthrough

Expo CLI and SDK web support beta

Using Expo for web in a expo init project

on how to upgrade to SDK 33 and how to configure and enable the web platform.

Expo-cli version is : '2.19.5'

I'm using Yarn

package.json

{
  "main": "node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "eject": "expo eject"
  },
  "dependencies": {
    "@expo/vector-icons": "latest",
    "expo": "next",
    "expo-cli": "^2.19.5",
    "expo-codemod": "^1.0.0",
    "expo-constants": "latest",
    "expo-image-manipulator": "latest",
    "expo-image-picker": "latest",
    "expo-intent-launcher": "latest",
    "expo-permissions": "latest",
    "firebase": "^5.8.1",
    "native-base": "^2.12.1",
    "react": "16.8.3",
    "react-dom": "^16.8.6",
    "react-firebaseui": "^3.1.2",
    "react-native": "https://github.com/expo/react-native/archive/sdk-33.0.0.tar.gz",
    "react-native-alert-async": "^1.0.3",
    "react-native-modal": "^9.0.0",
    "react-native-modal-datetime-picker": "^6.0.0",
    "react-native-picker-select": "^5.2.3",
    "react-native-web": "^0.11.4",
    "react-navigation": "^3.5.0-alpha.0",
    "react-redux": "^6.0.0",
    "redux": "^4.0.1",
    "redux-thunk": "^2.3.0",
    "rxjs": "^6.3.3",
    "schedule": "0.4.0",
    "uuid": "^3.3.2"
  },
  "devDependencies": {
    "babel-preset-expo": "^5.0.0",
    "prettier": "1.16.4"
  },
  "prettier": {
    "jsxBracketSameLine": true,
    "arrowParens": "always",
    "bracketSpacing": false
  },
  "private": true
}

This is the error I'm getting, Sorry I'm not sure at all how to fix it. I have updated expo and native base to the latest versions.

Any help would be greatly appreciated.

回答1:

This is because the Webpack config used by Expo CLI will automatically transpile any node_modules that start with expo, react-native, react-navigation, @expo, @react-navigation. Any other modules need to be manually added to the config file either by creating a new webpack config that extends @expo/webpack-config or by adding the module name to the app.json like so: https://github.com/hectahertz/react-native-typography/pull/31

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