Unable to resolve module `metro/src/lib/bundle-modules/HMRClient`

Question

I just upgraded from RN 0.55.4 to 0.59.3.....now Im getting following error:

Error: Unable to resolve module metro/src/lib/bundle-modules/HMRClient from ....\node_modules\react-native\Libraries\Utilities\HMRClient.js: Module metro/src/lib/bundle-modules/HMRClient does not exist in the Haste module map

The HMRClient.js file does include the following require statement: const MetroHMRClient = require('metro/src/lib/bundle-modules/HMRClient');.....and I cant see that path beginning with 'metro' anywhere so I guess I need to add it somehow. There is also another require statement as follows: const invariant = require('invariant'); ....no file name 'invariant' exists either.

Facebook say this was fixed back in 0.53.0 master but looks like its back https://github.com/facebook/react-native/issues/17742

Please help!

p.s. the below suggestion does not work

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-*.

can you go to your node modules folder and check if HMRClient.jsreally exists in the mentioned directory? — Reza Shoja

Pay attention when running npm install to see if there is any need for a specific version of something.

First check babel config files then if it doesn't work try the changes in package.json.

Try config files and deps as below. This is a config that worked for me for an update from 0.54 to 0.59.5:

package.json:

  " dependencies": {
         "react": "16.8.3",
         "react-native": "0.59.5",
         // ...
  },

  "devDependencies": {
    "@babel/core": "^7.0.0-0",
    "babel-core": "^7.0.0-bridge.0",
    "metro-react-native-babel-preset": "0.53.0",
    "react-test-renderer": "16.6.3",
    // ...
  }

babel.config.js:

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
};

.babelrc:

{
  "presets": ["module:metro-react-native-babel-preset"]
}

The only useful info I could find in the RN release notes about babel and metro changes was at [0.57] here:

https://github.com/react-native-community/releases/blob/master/CHANGELOG.md

UPDATE NOTE:

Trying config files as the ones from a new working project (created with 0.59.9) doesn't seem to work for an update from 0.54 to 0.59

babel.config.js:

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
};

metro.config.js:

module.exports = {
  transformer: {
    getTransformOptions: async () => ({
      transform: {
        experimentalImportSupport: false,
        inlineRequires: false,
      },
    }),
  },
};

and no .babelrc file.

package.json:

"devDependencies": {
    "@babel/core": "^7.4.5",
    "@babel/runtime": "^7.4.5",
    "metro-react-native-babel-preset": "^0.54.1",
  },
