I'll add my own special tale of Webpack --watch woe to the wall of suffering here.

I was running

webpack --watch

in order to build a Typescript project. The compiled .js files would update, but the bundle that the browser was seeing would not. So I was basically in the same position as the OP.

My problem came down to the watchOptions.ignored parameter. The original author of the build config had set up ignored as a filter function, which turns out to not be a valid value for that parameter. Replacing the filter function with an appropriate RegExp got the --watch build working again for me.
