将世博会 26 升级到 32 后世博会开始不起作用

Question

After upgrading expo from: SDK 26 to SDK 32, I have the following issue when I use expo run emulator or expo app :

/Users/name user/project name/node_modules/expo/AppEntry.js: Cannot read property '1' of undefined

AppEntry.js:

import { KeepAwake, registerRootComponent } from 'expo';
import App from '../../App';


if (__DEV__) {
   KeepAwake.activate();
}

registerRootComponent(App);

package.json:

{
   “main”: “node_modules/expo/AppEntry.js”,
   “private”: true,
   “scripts”: {
      “test”: “node ./node_modules/jest/bin/jest.js --watchAll”
   },
   “jest”: {
       “preset”: “jest-expo”
   },
   “dependencies”: {
       “@expo/samples”: “2.1.1”,
       “babel-preset-expo”: “^5.1.1”,
       “expo”: “^32.0.0”,
       “npm”: “^4.6.1”,

       “@babel/core”: “^7.4.3”,
       “@babel/preset-env”: “^7.0.0-beta.47”,
       “gulp-babel”: “^7.0.1”,
       “jest-expo”: “^32.0.0”
    }
}

EDIT: After adjusting at the suggestion, I'm getting this error:

Users/user name/project name/App.js: Cannot read property 'filename' of undefined

Any ideas on potential solutions to try? Any help would be greatly appreciated!

Answer 1

Looking at the issue log for expo , I see someone else had a similar issue when updating from:

SDK version 30 to SDK version 31

and the issue was related to their babel configuration. Perhaps you're dealing with the same issue, maybe you could try the solution they suggested and see if that resolves your issue as well since you're updating from SDK version 26.

Here is what they suggested:

Install the latest version of babel-plugin-module-resolver :

npm i --save-dev babel-plugin-module-resolver@latest

alternatively:

yarn add babel-plugin-module-resolver@latest

Additionally, others had to change their .babelrc contents to use the "babel-preset-expo" preset:

.babelrc

{
  "presets": ["babel-preset-expo"]
} 

Hopefully that helps!
