This dependency was not found in node_modules: * pace

When I do

    'resources/assets/js/core/libraries/jquery.min.js', // 2.1.4
    'resources/assets/js/core/libraries/bootstrap.min.js', // v3.3.6
    'resources/assets/js/core/app.js',
], 'public/js/guest_app.js');

it works well

but when I add a line:

    'resources/assets/js/plugins/loaders/pace.min.js',
    'resources/assets/js/core/libraries/jquery.min.js', // 2.1.4
    'resources/assets/js/core/libraries/bootstrap.min.js', // v3.3.6
    'resources/assets/js/core/app.js',
], 'public/js/guest_app.js');

I get :

 ERROR  Failed to compile with 1 errors

Did you forget to run npm install --save for it?

Why is it asking me for pace module?

That solved it. Not sure why that wasn’t installed. Using regular NPM, not Yarn.
