What's your node/npm version?
Have you added ssh key to github account?

Hi, I found the resolution. There is a mistake in package.json

I have changed following lines:
"postinstall": "gulp --gulpfile bin/gulpfile.js copy-libs && npm install ./bin/cec --no-save || npm install .\bin\cec --no-save",
"install-cec": "npm install -g ./bin/cec"

It will work
