Why can't I run Webpack with React? - node.js

Question

For several days, I am trying to install webpack with React. I used several tutorials but I can' t still install it. Recently, I used this tutorial but in the last step, when I try to run webpack I get an error:
The CLI moved into a separate package: webpack-cli.
Please install 'webpack-cli' in addition to webpack itself to use the CLI.
-> When using npm: npm install webpack-cli -D
-> When using yarn: yarn add webpack-cli -D
Then, I run npm install webpack-cli -D, but it doesn't help and I don't know how to resolve that problem. When I try to only install webpack I receive the same error. Thanks for advices.
package.json and webpack.config.js content:
{
"name": "proj",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"

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

{ enforce: "pre", 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.

Ok I solve my problem. First of all, I deleted "webpack-cli": "^2.0.10" from my package.json. Then I install npm install webpack#3.0.0 and add to package.json: "scripts": {
"build": "webpack --config webpack.config.js"
}, Now I can run my webpack by npm run-script build. Thanks a lot.
