Description

Trying to run the app through xcode (IOS) and metrobundler, I am getting this error

error: bundling failed: Error: Unable to resolve module @babel/runtime/helpers/interopRequireDefaultfrom/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-*.

    BUNDLE [ios, dev] ./index.js ░░░░░░░░░░░░░░░░ 0.0% (0/1), failed.`

Tried the steps:

Clear watchman watches: watchman watch-del-all.
Delete the node_modules folder: rm -rf node_modules && npm install.
Reset Metro Bundler cache: rm -rf /tmp/metro-bundler-cache-* or npm start -- --reset-cache.
Remove haste cache: rm -rf /tmp/haste-map-react-native-packager-*.
npm add @babel/runtime npm install


Uninstalling watchman


npm add @babel/runtime --save-dev


Added "ignore_dirs": ["node_modules"] in .watchmanconfig


react-native start --reset-cache


Nothing seems to work. And I am stuck with this error. This is my system info:

react-native-cli: 2.0.1, react-native: 0.59.9

watchman --version 4.9.0

"@babel/runtime": "7.0.0", "@babel/cli": "7.5.0", "@babel/core": "7.5.4"

Checked file: @babel/runtime/helpers/interopRequireDefault which is present at the given location

Thanks for going through this.

Research direction

Start by reproducing the iOS bundle failure from index.js and inspect the Metro resolution paths shown in the error, especially the lookup for @babel/runtime/helpers/interopRequireDefault. Review the listed cache, Watchman, and dependency-reset commands, then verify completion when Metro bundles the app without the missing-module error.
