Errow with Webpack serve Command-CodePudding

Trying to create a React app with Webpack and Babel. Followed a tutorial on YouTube and some other Tutorials on different Websites and if i run the webpack serve command i run into this error every time. Even if index.js contains nothing.

[ERROR]:

CodePudding user response：

Ok guys fixed it. Took me one day to realise that the version of [email protected] doesn't work with babel-loader. So I installed [email protected] and downgraded other devDepencies. Now it's working like a charm.

EDIT: Nice to know. If you want to use asynchronus functions in react Just add browserlist like below to your package.json file.
