Uncaught TypeError: __webpack_require__(...).filter is not a function

[p2227]

step1

npm install -g yo generator-react-webpack-redux

step2

# Create a new directory, and `cd` into it:
mkdir my-new-project && cd my-new-project

# Run the generator
yo react-webpack-redux

now if you npm start it works.
step3

npm i react-router react-router-proxy-loader -S

step4
modify index.js and add

import 'react-router';
import 'react-router-proxy-loader';

then it throw error above

the error code is

loader-utils/index.js

Line 5 in ee056c9

var emojiList = require("emojis-list").filter(function(emoji) {

var emojiList = require("emojis-list").filter(function(emoji) {
    return emojiRegex.test(emoji)
});

step5
modify index.js:

import 'react-router';
// import 'react-router-proxy-loader';

there is no error again

I think there are some conflicts between webpack loader-utils emojis-list and react-router-proxy-loader

[p2227]

finally I solve it by adding json-loader

the conflict is : emojis-list exports a json file. there is no problem while it is in node environment.
but in webpack , the require function is rewrite to __webpack_require__ . it can't load json file without json-loader

The loader-utils are designed to be used in a node.js environment. I cannot think of a situation where you want to include your loader in your bundle :)
