Webpack with typescript not finding entry module

I am attempting to integrate webpack into my typescript application. In order to learn webpack I attempted a minimal migration. So I cloned the Angular2 quickstart seed, added a webpack.config.js:

'use strict';
let path = require('path');

module.exports = {
    entry: './app/main.ts',
    module: {
        rules: [
            {
                test: /\.tsx?$/,
                loader: 'awesome-typescript-loader',
                exclude: /node_modules/,
            },
        ]
    },
    output: {
        filename: '/bundle.js',
        path: path.resolve(__dirname, 'dist')
    },
    resolve: {
        extensions: [".tsx", ".ts", ".js"]
    },
};

And attempted a build:

PS C:\Users\ltheisen\git\pastdev-test-webpack> .\node_modules\.bin\webpack --display-error-details
Hash: 954fdea72e6d10e35648
Version: webpack 1.14.0
Time: 31ms

ERROR in Entry module not found: Error: Cannot resolve 'file' or 'directory' ./app/main.ts in C:\Users\ltheisen\git\pastdev-test-webpack
resolve file
  C:\Users\ltheisen\git\pastdev-test-webpack\app\main.ts.tsx doesn't exist
  C:\Users\ltheisen\git\pastdev-test-webpack\app\main.ts.ts doesn't exist
  C:\Users\ltheisen\git\pastdev-test-webpack\app\main.ts.js doesn't exist
resolve directory
  C:\Users\ltheisen\git\pastdev-test-webpack\app\main.ts\package.json doesn't exist (directory description file)
  C:\Users\ltheisen\git\pastdev-test-webpack\app\main.ts is not a directory (directory default file)

From the --display-error-details output, I can see that it check the file with all 3 extensions from resolve.extensions, but not for the file itself. All of the examples I have found use the file with the extension for entry (webpack basic setup, typescript integrating with build tools, ...). If I remove the extension, the webpack build finds the entry file (though I seem to have other problems...).

Anyway, my question is this: am I doing something wrong? Missing something obvious? Or is the documentation wrong?

---- UPDATE ---- It appears it may be something wrong with the npmjs repository. Specifically, the webpack 2 documentation for installation says:

npm install webpack --save-dev

However, npmjs shows shows version 1.14.0 as the current version:

enter image description here

This seems odd because version 2.2.0 was released last week... But i guess the release hasn't yet propagated to npmjs? After updating to webpack 2, this seems to have resolved my problem...

Webpack 2 has been at pre-release stage until this moment. I cannot say why 2.2.0 isn't tagged accordingly if it is considered unstable, but it was published this way, npm dist-tag ls webpack outputs:

beta: 2.2.0

latest: 1.14.0

Use appropriate semver to install it:

npm install webpack@2 --save-dev

npm shows last published version, use npm view webpack to find all versions.
