Error: Unable to find file with empty: prelude_dev.js

I get the following error when running the package:

I already ran:

rm -rf node_modules
npm cache clean
npm install

I am currently running React Native 0.24.0.

This is a cache problem. See: https://github.com/facebook/react-native/issues/1924

You need to clear the packer cache:

rm -fr $TMPDIR/react-*

Or this seems to do the trick too:

watchman watch-del-all

If you use your own rn-cli.config.js, try without it.

I spent many hours on this with the bad rn-cli.config.js file. He worked for a while until he did.

In my case, I used this:

var blacklist = require('react-native/packager/blacklist');
var config = {
    getBlacklistRE(platform) {
        return blacklist(platform, [
            /src/
        ]);
    }
};
module.exports = config;

when I should have used this instead:

var blacklist = require('react-native/packager/blacklist');
var config = require('react-native/packager/rn-cli.config');
config.getBlacklistRE = function(platform) {
    return blacklist(platform, [
        /src/
    ]);
};
module.exports = config;
