An error occurred during the packager process. Exited with code 1.
Look at the packager output above to see what went wrong.

Based on this comment facebook/react-native#20799 (comment) I updated line 4 in rn-cli.config.js from var blacklist = require('metro/src/blacklist'); to var blacklist = require('metro-config/src/defaults/blacklist');

[yukinoda]

Thank you for the comment @chidinmae .

I tried the same solution from facebook/react-native/issues/21093 but the following warning appears in my terminal window

Starting React Native Packager...
● Validation Warning:

  Unknown option "getProjectRoots" with value getProjectRoots() {
    return getRoots();
  } was found.
  This is probably a typing mistake. Fixing it will remove this message.

● Validation Warning:

  Unknown option "getBlacklistRE" with value getBlacklistRE() {
    return blacklist([
    ]);
  } was found.
  This is probably a typing mistake. Fixing it will remove this message.

● Validation Warning:

    return ['obj', 'mtl'];
  } was found.
  This is probably a typing mistake. Fixing it will remove this message.

● Validation Warning:

  Unknown option "getPlatforms" with value getPlatforms() {
    return ['vr'];

  This is probably a typing mistake. Fixing it will remove this message.

● Validation Warning:

  This is probably a typing mistake. Fixing it will remove this message.

and shows only a blank page in my browser with the following errors in the console.

Not sure about this one! The error I got after fixing the rn-cli config was related to watchman and fixed by running brew install watchman. Maybe try npm install metro for this?

Not running npm audit fix helped me.

I found a solution. If you're using react native >= 0.59 change your file name rn-cli.config.js to metro.config.js.

Then change your code, for example:

const blacklist = require('metro-config/src/defaults/blacklist');

module.exports = {
    getBlacklistRE() {
        return blacklist([
            /scripts\/.*/,
        ]);
    },
};

To:

const blacklist = require('metro-config/src/defaults/blacklist');

module.exports = {
    resolver: {
        blacklistRE: blacklist([/scripts\/.*/])
    },
};

Following the documentation from metro.
