browser-sync: Module BrowserSync is not available! You either misspelled the module name [...]

Issue details

I am trying to use browser-sync inside a ghost template so I can reload the browser when changes have been made. When I navigate to localhost:3001, I can see the UI skeleton without any data (still in loading state):

When I look into the console (of the browser-sync UI at port 3001), I can see these errors, what did I do wrong? I’ll attach the errors in text form at the end of this issue.

Steps to reproduce/test case

I am simply using

browserSync.init({
  proxy: "localhost:2368",
});

in my gulp file and I tried browser-sync versions 2.27.4, 2.27.1 and 2.26 (with no success).

Please specify which version of Browsersync, node and npm you’re running

• Browsersync [2.27.4, 2.27.1, 2.26]
• Node [12.22.1]
• Npm [6.14.12]

Affected platforms

• windows

Browsersync use-case

• Gulp

const browserSync = require("browser-sync").create();
browserSync.init({
  proxy: "localhost:2368",
});

and then browserSync.stream() at some places but this shouldn’t be related to the problem at hand.
