Module build failed: Error: Plugin/Preset files are not allowed to export objects, only functions.

I’m trying to use babel-loader to pack some imported functions to export it to firebase, but the same error is happening every time.

Module build failed: Error: Plugin/Preset files are not allowed to export objects, only functions.

I just don’t know what to try anymore.

webpack.config.js

module.exports = {
  entry: './src/index.js',
  output: { path: __dirname, filename: 'index.js' },
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /(node_modules|bower_components)/,
        use: {
          loader: 'babel-loader',
          options: {
            presets: ['@babel/preset-env']
          }
        }
      }
    ]
  }
}

Full error

I found a solution using babelrc: false under options. Using under query gaves and error.

{
    test: /\.js$/,
    exclude: /(node_modules|bower_components)/,
    use: {
        loader: 'babel-loader',
        options: {
            babelrc: false,
            presets: ['@babel/preset-env']
        }
    }
}
