Update Your Dependencies
Ensure your project dependencies are up to date. Clean the npm cache and reinstall all dependencies:

}
Reinstall Vue-Loader
Sometimes, simply reinstalling vue-loader can resolve the issue:
npm install vue-loader --save-dev
Check Your Webpack Configuration
Double-check your webpack.config.js file to ensure vue-loader is properly configured:
const { VueLoaderPlugin } = require('vue-loader');
module.exports = {
mode: 'development',
module: {
rules: [
{
test: /\.vue$/,
loader: 'vue-loader'
}
]
},
plugins: [
new VueLoaderPlugin()
]
};
Verify Paths and Typos
Ensure there are no typos in your import paths and that all required files are correctly placed in your project directory.
