Description

When starting a new project with react-native init then run iOS, I’m getting the error :

Module @babel/runtime/helpers/interopRequireDefault does not exist in the Haste module map

Reproducible Demo

react-native init myapp // FIX CFBundleIdentifier issue with react-native upgrade react-native run-ios Get the error.

FIX

The issue can be fix by doing: npm add @babel/runtime npm install But we shouldn’t have to do all this stuff !

for now since a lot of new changes are coming out, this fix worked for me: with npm: npm install --save @babel/runtime or with yarn: yarn add @babel/runtime (edited: if you’re planning on waiting for the release that fixes this before releasing a new production build (like me) you can keep babel/runtime in devDependencies, but if you want to build a release build with this version of react-native, you need to put @babel/runtime in dependencies as the original poster said)

if on ios you get _this._registerEvents is not a function, after a successful build do npm run start --reset-cache or react-native start --reset-cache

edit: should add @babel/core, under resolutions, in package.json you may also need “babel-core”: “7.0.0-bridge.0” in resolutions but this is more for react-native projects being upgraded…

@hugoh59 Same for me, I’m really shocked. I tried everything. RN is a piece of shit
