Prod build error on loading @angular/core.js

[RobNordon]

Upon building the production version gulp build.prod an error is caused in the build.bundles.app task which stops the build.

[14:01:36] Starting 'build.bundles.app'...
Unhandled rejection Error on fetch for @angular/core.js at file:///C:/Dev/angula

You may need to:

rm -rf node_modules typings
git pull
npm install
npm run build.prod

Thanks Nathan, however the same error results.

I'm using Node v6.1.0, NPM v3.8.8 on Windows 7.

This may be a specific version issue with Windows. @d3viant0ne Do you happen to have a Windows setup to help test this out?

I am also facing the same issue with the prod build.

The error i get is as below:

Unhandled rejection Error on fetch for @angular/core.js at file:///C:/****/node_modules/@angular/core.js
        Loading dist/tmp/main.js
        Error: ENOENT: no such file or directory, open 'C:\*****\node_modules\@angular\core.js'

I will fix this tomorrow. Most likely wrong system builder config.

[AntonyBaasan]

Thanks mgechev. In my case: Windows 10, Node v6.0.0, npm 3.8.6

[NathanWalker]

@mgechev I was able to test the fix out with VirtualBox... You were right, system builder config just needed packages. Went ahead and cleared everyone here.
