Webpack cannot find module

I'm new on webpack and I'd like to use third party react component in my project. I installed the componet that i need and the dir node_modules was created and my project's tree look like:

reactcalendar
  |--node_modules
  |   |--.bin
  |   |--babel-cli
  |   |--babel-core
  |   |--babel-preset-es2015
  |   |--babel-preset-react
  |   |--babelify
  |   |--file-loader
  |   |--moment
  |   |--react
  |   |--react-big-calendar (the third party component)
  |   |--react-dom
  |   |--webpack
  |--.babelrc
  |--bundle.js (empty)
  |--index.html
  |--index.js
  |--package.json
  |--webpack.config.js

Some file was used for browserify but it gave me the same error...

My index.html look like this:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>React Calendar</title>
    <script src="bundle.js" type="text/javascript"></script>
</head>
<body>
    <div id="content"></div>
</body>
</html>

My index.js look like this:

import BigCalendar from 'react-big-calendar';
import moment from 'moment';
BigCalendar.momentLocalizer(moment);

ReactDOM.render(<BigCalendar
    events={myEventsList}
    startAccessor='startDate'
    endAccessor='endDate'
/>, document.getElementById('content'));

And my webpack.config.js look like this:

module.exports = {
    context: __dirname,

    output: {
        filename: "bundle.js",
        path: __dirname
    },

    module: {
        loaders: [
            {
                test: /\.js$/,
                exclude: /node_modules/,
                loaders: ["babel-loader"]
            },
            {
                test: /\.html$/,
                loader: "file?name=[name].[ext]",
            }
        ]
    },

    entry: {
        javascript: "./index.js",
        html: "./index.html"
    }
}

When i run the command webpack into my root project it gave me this error:

C:\Users\ernest\PhpstormProjects\reactcalendar>webpack
Hash: ebfe4ff0eeeaed3060c6
Version: webpack 1.13.1
Time: 12753ms
     Asset       Size  Chunks             Chunk Names
index.html  231 bytes          [emitted]
 bundle.js     469 kB    0, 1  [emitted]  html, javascript
    + 105 hidden modules

ERROR in ./index.js
Module not found: Error: Cannot resolve module 'react-big-calendar' in C:\Users\ernest\PhpstormProjects\reactcalendar
 @ ./index.js 3:24-53

Maybe I'm wrong with the config file of webpack?

I'm not using React, but my problem was solved by setting the module field in tsconfig.json from UMD to AMD.

{
  "compilerOptions": {
    "module": "AMD",
    "target": "ES5",
    "declaration": true,
    "outDir": "./dist",
    "moduleResolution": "node"
  },
  "exclude": [
    "node_modules"
  ],
  "include": [
    "src/**/*"
  ]
}

1.delete node_modules folder.

2.then npm install

3.Change your code in index.js to this

import {render} from 'react-dom';
import React from 'react';
import BigCalendar from 'react-big-calendar';
import moment from 'moment';

BigCalendar.setLocalizer(BigCalendar.momentLocalizer(moment));
const myEventsList = [{'event':'test2'},{'event':'test1'},{'event':'test3'}]

render(<BigCalendar
    events={myEventsList}
    startAccessor='startDate'
    endAccessor='endDate'
/>, document.getElementById('content'));

4.in index.html you should put bundle.js into body

<body>
    <div id="content"></div>
    <script src="bundle.js" type="text/javascript"></script>
</body>
