Typescript/Webpack: cannot find module 'react-select'

I'm trying to set up React with typescript, i followed the tutorial here. I installed react-select but when i try to reference it i get a compiler error Build: Cannot find module 'react-select', i get the same error if i try to run webpack from the cmd line.

I tried including the following loader as suggested as a fix on github but I get the same error.

 {
    test: /\.js$/,
    include: path.join(__dirname, 'node_modules', 'react-select'),
    loader: 'jsx-loader',
  }

Any ideas?

UPDATE:

tsconfig.json

{
    "compilerOptions": {
        "outDir": "./dist/",
        "sourceMap": true,
        "noImplicitAny": true,
        "module": "commonjs",
        "target": "es6",
        "jsx": "react"
    },
    "files": [
        "./typings/index.d.ts",
        "./src/components/Hello.tsx",
        "./src/index.tsx"
    ]
}

package.json:

{
  "name": "react-typescript-setup",
  "version": "1.0.0",
  "main": "./dist/bundle.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "webpack": "webpack -w"

    "style-loader": "^0.13.1",
    "ts-loader": "^0.8.2",
    "typings": "^1.3.3"
  },
  "description": ""
}

webpack.config.js

var path = require('path');

module.exports = {
    entry: "./src/index.tsx",
    output: {
        path: __dirname,
        filename: "./dist/bundle.js",
    },

    // Enable sourcemaps for debugging webpack's output.
    devtool: "source-map",
    debug: true,

    resolve: {
        // Add '.ts' and '.tsx' as resolvable extensions.
        extensions: ["", ".webpack.js", ".web.js", ".ts", ".tsx", ".js"]
    },

    module: {
        loaders: [
            // All files with a '.ts' or '.tsx' extension will be handled by 'ts-loader'.
            { test: /\.tsx?$/, loader: "ts-loader" },
            {
                test: /\.css$/,
                loader: 'style!css-loader?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]'
            }
        ],

        preLoaders: [
            // All output '.js' files will have any sourcemaps re-processed by 'source-map-loader'.
            { test: /\.js$/, loader: "source-map-loader" }
        ]
    },

    // When importing a module whose path matches one of the following, just
    // assume a corresponding global variable exists and use that instead.
    // This is important because it allows us to avoid bundling all of our
    // dependencies, which allows browsers to cache those libraries between builds.
    externals: {
        "react": "React",
        "react-dom": "ReactDOM"
    },
};

I fixed it by pointing into the dist file:

import CreatableSelect from "react-select/creatable/dist/react-select-creatable.cjs";

I was looking at my packges and I found that react-select package is missing from @types in node_modules, so I ran this command # npm install --save @types/react-select and it solved it.

First of all you need to install the typings for react-select in order to import it. Once you do that go to the installed typings and check the type of export being done.

In case it is something like export = Select you need to do import = require('react-select')

In case it is something like export default Select you need to do import Select fromreact-select`

In case of named exports i.e export {Select} you need to do import {Select} from 'react-select'

In case of multiple named exports you will have to explicitly import each export or do import * as Select from 'react-select'

According to the typings for react-select as shown here the module exports its contents through a default export at the bottom of the file. So import ReactSelect from 'react-select' should work for you

Configuring Typsecript with webpack should be defined something like that: 

module.exports = {
  entry: "./app/boot",
  output: {
    path: __dirname,
    filename: "./dist/bundle.js"
  },
  resolve: {
    extensions: ['', '.js', '.ts']
  },
  module: {
    loaders: [
      { test: /\.ts/,   loader: ["ts-loader"], exclude: /node_modules/ },
    ],
    preLoaders: [
      // All output '.js' files will have any sourcemaps re-processed by 'source-map-loader'.
      { test: /\.js$/, loader: "source-map-loader", exclude: ['node_modules', 'ext-*', 'lib', 'tools'] }
    ]
  },
  debug: true,
  devtool: 'source-map'
};

The ts-loader loads the enables the Typescript to the browser and the source-map-loader loads the source-maps to the browser for easier debugging.

Let me know if you need anything or if I misunderstood you.
