问题:

When creating a new react native project using the standard react-native init MyApp and running react-native run-ios for the first time I'm seeing the following error

error: bundling failed: Error: Unable to resolve module `@babel/runtime/helpers/interopRequireDefault` from `/Users/chrisedgington/Development/ReactNative/SixNationsPredictor/index.js`: Module `@babel/runtime/helpers/interopRequireDefault` does not exist in the Haste module map  This might be related to https://github.com/facebook/react-native/issues/4968 To resolve try the following:   1. Clear watchman watches: `watchman watch-del-all`.   2. Delete the `node_modules` folder: `rm -rf node_modules && npm install`.   3. Reset Metro Bundler cache: `rm -rf /tmp/metro-bundler-cache-*` or `npm start -- --reset-cache`.   4. Remove haste cache: `rm -rf /tmp/haste-map-react-native-packager-*`.     at ModuleResolver.resolveDependency (/Users/chrisedgington/Development/ReactNative/MyApp/node_modules/metro/src/node-haste/DependencyGraph/ModuleResolution.js:209:1301)     at ResolutionRequest.resolveDependency (/Users/chrisedgington/Development/ReactNative/MyApp/node_modules/metro/src/node-haste/DependencyGraph/ResolutionRequest.js:83:16)     at DependencyGraph.resolveDependency (/Users/chrisedgington/Development/ReactNative/MyApp/node_modules/metro/src/node-haste/DependencyGraph.js:238:485)     at Object.resolve (/Users/chrisedgington/Development/ReactNative/MyApp/node_modules/metro/src/lib/transformHelpers.js:180:25)     at dependencies.map.result (/Users/chrisedgington/Development/ReactNative/MyApp/node_modules/metro/src/DeltaBundler/traverseDependencies.js:311:29)     at Array.map (<anonymous>)     at resolveDependencies (/Users/chrisedgington/Development/ReactNative/MyApp/node_modules/metro/src/DeltaBundler/traverseDependencies.js:307:16)     at /Users/chrisedgington/Development/ReactNative/MyApp/node_modules/metro/src/DeltaBundler/traverseDependencies.js:164:33     at Generator.next (<anonymous>)     at step (/Users/chrisedgington/Development/ReactNative/MyApp/node_modules/metro/src/DeltaBundler/traverseDependencies.js:266:307) 

I've tried running the suggested but still see the same issue. I've seen a few posts about similar issues but nothing specifically seems to say how to resolve the problem in react-native.

macOS: 10.13.6  node: 8.11.3 react-native-cli: 2.0.1 react-native: 0.57.1 

回答1:

Have a go and try:

npm add @babel/runtime

Or upgrade babel runtime:

"@babel/runtime": "7.0.0-beta.55"



回答2:

Try to update your npm version first

npm update -g npm@version or sudo npm -gf update npm@version

and then just add the babel runtime at your react native project

npm add @babel/runtime



回答3:

You should first quit the metro terminal before executing

npm add @babel/runtime npm install
