I am currently taking a course on Udemy and I am stuck, I am having a problem running script. When I run the command npm run dev, I get this error message:
npm ERR! code ELIFECYCLE
npm ERR! errno 2
npm ERR! forkify#1.0.0 dev: `webpack`
npm ERR! Exit status 2
npm ERR!
npm ERR! Failed at the forkify#1.0.0 dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

What would be wrong? This is my package.json code:
{
"name": "forkify",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"dev": "webpack",
"build": "webpack --mode production",

"webpack-cli": "^3.2.1",
"webpack-dev-server": "^3.1.14"
},
"dependencies": {
"babel-polyfill": "^6.26.0"
}
}
Here is the webpack.config.js code:
const path = require('path');
module.exports = {
entry: './src/js/index.js',
output: {
path: path.resolve(__dirname, 'dist/js'),
filename: 'bundle.js'
},
mode: 'development'
};
What could be wrong?
UPDATE: Some way I was able to finally npm run dev but it is being created in the wrong directory. How can I solve this?
I need it to appear under the starter > dist > js
Your path are not good replace entry: './src/js/index.js' by entry: './started/src/js/index.js'

I am setting up a React project using webpack and babel, but I am getting the error that React and ReactDOM can't be resolved.
Is the problem is with the version of Webpack or Babel?

Please Help
This code looks fine to me. I think you have missed the dependency installation step before running webpack command.
Please try and follow the below steps in order and see if it resolves the error.
Run npm install inside the directory this will make sure all the dependencies you have mentioned in package.json are downloaded to node_modules directory.
Then run npm run webpack to generate the bundle.js

Failed at the reactjs#1.0.0 it script 'webpack-dev-server'.
Make sure you have the latest version of node.js and npm installed.
If you do, this is most likely a problem with the reactjs package,
not with npm itself. Tell the author that this fails on your system:
webpack-dev-server You can get information on how to open an issue for this project with:npm bugs reactjs Or if that isn't available, you can get their info via: npm owner ls reactjs There is likely additional logging output above.

Looks like webpack-dev-erver isn't installed. Please install it globally and retry.
In commandline, install Webpack Dev Server via
npm install --save webpack-dev-server
Good day, i'm currently doing a tutorial on scotch.io where i'm trying to make a music player using electron and react, but when i try to execute 'npm run watch' i get this error message:

From what i've read in the tutorial browserify is supposed to come with watchify as well, however when i installed it as a separate module it worked but then i got the following error:
console.error("SyntaxError: C:/Users/Alejandro/Documents/Proyectos/music-player/app/app.js: Unexpected token (12:10) while parsing file: C:\Users\Alejandro\Documents\Proyectos\music-player\app\app.js");
I used the same tutorial, but I could not get everything working by applying the code snippets from the tutorial.
Do this instead:
install both browserify and watchify:
npm install -g browserify watchify
clone the author's music player github repository instead of electron-quick-start. Then add or modify the tutorial code snippets.
