Can't find module

[huxulm]

After I installed all packages use: npm install and run with: npm start.
Then:

ERROR in /Users/xulingming/Public/git_repos/material.angular.io/src/app/shared/example-
 
viewer/example-viewer.ts (5,47): Cannot find module '@angular/material-examples'.

After checked the package.json file, I couldn't find this package dependency was added.
It seems there is no @angular/material-examples package in npm registry.

I found this: #160 , solved the problem.
