Problem with hello world script

CesiumJS

1. A concise explanation of the problem you're experiencing.

I am running the Helloworld tutorial as found here

I have installed Cesium and nodejs as explained.
Then ran npm install in the Cesium root directory.. It installed a bunch of stuff(dependencies?) in the folder node_modules

I then type node server.js
I get a bunch of errors.

Error log found in npm-debug.log is attached

Hi there,

I downloaded the latest Cesium, and extracting the zip, navigated to that folder, and ran:

npm install

npm start

And it worked fine. I also tried node server.js instead of npm start. That worked fine as well. Did everything install correctly? Try running npm install again and make sure you’re not getting any errors. Also double check you’re running the command in that root folder.

Thanks!
