webpack.confi.js

const path = require('path')

module.exports = {
  entry: path.resolve(__dirname, 'frontend/src', 'index.js'),
  output: {
    path: path.resolve(__dirname, 'frontend/static/main.js'),
    filename: 'main.js'

        use: {
          loader: 'babel-loader',
        
      }
    ]
  },

}

Visual error.

If more code is require then tell me in a comments. I'll update my question with that information thank you.

Answer 1

@babel/core is not a preset, remove that from the presets array in your babelrc.
