NPM run watch cant find module webpack

Question

I have a package.json which contains some packages. Once i use npm install it will install all the items required, but it also creates symlinks:

/Users/donny/Sites/Homestead/node_modules/lodash -> /usr/local/lib/node_modules/lodash

/Users/donny/Sites/Homestead/node_modules/underscore -> /usr/local/lib/node_modules/underscore
/Users/donny/Sites/Homestead/node_modules/less -> /usr/local/lib/node_modules/less
/Users/donny/Sites/Homestead/node_modules/axios -> /usr/local/lib/node_modules/axios
/Users/donny/Sites/Homestead/node_modules/bootstrap -> /usr/local/lib/node_modules/bootstrap

/Users/donny/Sites/Homestead/node_modules/vue -> /usr/local/lib/node_modules/vue

After this i try to run npm run watch and then i get the error

events.js:160
      throw er; // Unhandled 'error' event
      ^

Error: spawn node_modules/webpack/bin/webpack.js ENOENT
    at exports._errnoException (util.js:1020:11)
    at Process.ChildProcess._handle.onexit (internal/child_process.js:193:32)
    at onErrorNT (internal/child_process.js:367:16)
    at _combinedTickCallback (internal/process/next_tick.js:80:11)
    at process._tickCallback (internal/process/next_tick.js:104:9)
    at Module.runMain (module.js:606:11)
    at run (bootstrap_node.js:389:7)
    at startup (bootstrap_node.js:149:9)
    at bootstrap_node.js:504:3

Someone knows how to solve this?

Please check your index.html it should be

 <!-- Ionic's root component and where the app will load --> <ion-app></ion-app> <!-- The polyfills js is generated during the build process --> <script src="build/polyfills.js"></script> <!-- all code from node_modules directory is here --> <script src="build/vendor.js"></script> // <-- Include this line. <!-- The bundle js is generated during the build process --> <script src="build/main.js"></script> 

This problems can also be easily solved by reinstalling your Ionic and Cordova.
