[HMR] Hot Module Replacement is disabled.

[AndrejGajdos]

When I build project and open index.html file, I get error:

GET file:///bundle.js net::ERR_FILE_NOT_FOUND

I tried to comment line <base href="/"> in index.html and then bundle.js is loaded, but get error:

Uncaught Error: [HMR] Hot Module Replacement is disabled.

In an attempt to reproduce this error, I cloned the webpack-bootstrap repo and then ran "npm install". After this, I was able to navigate to the index page with no problems.

Try deleting the node_modules folder and reinstalling them again (follow the instruction on the repo's front page).
