How to spell alias correctly?

Question

webpack

Tell me what I'm doing wrong.
I write an alias to webpack.mix.js, but it always gives me a path error.
To test and check the correctness of the path, I created a directory and a file:

mix.webpackConfig({
    resolve: {
        alias: {
            Utilities: path.resolve(__dirname, 'test/test.js'),
        }
    }
});

Mistake:
[webpack-cli] ReferenceError: path is not defined
