Q:

Nuxt.js: fsevents is not a constructor

I'm using MacOS Mojave 10.14.5.  When I run 'npm run dev' command where the nuxt starter package is located, I have 'fsevents' error, and the server doesn't work. 
I already reinstall node and npm several times, but it doesn't work. 
Here's an error:
/Users/kimgyun/Desktop/nuxt_test_folder/nuxt_test_b/node_modules/watchpack/node_modules/chokidar/lib/fsevents-handler.js:28
return (new fsevents(path)).on('fsevent', callback).start();
          ^

How can I run this nuxt.js server without this error? 

A:

It's a problem with fs events, and a rather annoying one  at that.  Specifically this happens when you're using Node 12. 
You'll need to install fsevents@1.2.9 explicitly:
npm i fsevents@1.2.9 -D

or
yarn add fsevents@1.2.9 -D

This should work for you at this point.
