I was following https://dev.office.com/sharepoint/docs/spfx/set-up-your-development-environment on Windows 10 machine. I opened command prompt window in Admin mode. installing NodeJS, npm and then npm install -g yo gulp and npm install -g @microsoft/generator-sharepoint completed successfully.
On the next page, https://dev.office.com/sharepoint/docs/spfx/web-parts/get-started/build-a-hello-world-web-part I created new folders (
md helloworld-webpart, then
cd helloworld-webpart) and started
yo @microsoft/sharepoint
After running for minutes, I've got

I tried a couple of times and got the same result.
npm -v 3.10.10 Node -v v7.5.0
I found similar questions: Gulp serve error : Cannot find module '@microsoft/sp-build-web' and Yeoman generator for WebPart can't find Github repo #spfx #spfx-webparts #spfx-tooling but none of the suggestions helped.
