const { VueLoaderPlugin } = require('vue-loader');
module.exports = {
mode: 'development',
module: {
rules: [
{
test: /\.vue$/,
loader: 'vue-loader'
}
]
},
plugins: [
new VueLoaderPlugin()
]
};

Ensure there are no typos in your import paths and that all required files are correctly placed in your project directory.
