Webpack Error - Cannot Resolve File or Directory

Question

I am getting this error when I npm start my webpack-dev-server:

ERROR in multi main
Module not found: Error: Cannot resolve \'file\' or \'directory\' /var/ww         


        

Answer 1

You should check the browser console. It provides more detailed informations.

In my case:

Uncaught Error: Cannot find module "./src/index"
at webpackMissingModule (webpack:///multi_main?:4)
at eval (webpack:///multi_main?:4)
at Object. (bundle.js:586)
at __webpack_require__ (bundle.js:556)
at bundle.js:579
at bundle.js:582

So here is the error a missing (or misspelled) java script file.
