Error with install angular-cli with node-sass

Question

My system configuration:
debian 4.4 , nvm 0.33.8 , node v8.9.4 , npm 5.6.0 .

I want to install Angular-cli npm install -g @angular/cli. But I get an error message:

root@contracts:/home/kalugin# npm install -g @angular/cli

I tried npm cache clean, doesn't help.
I tried change node version nvm use v6.12.3, doesn't help.

debug.log pointed to the problem with node-sass package. I tried install node-sass globally - but the same error. I cannot install node-sass...

Any ideas?

Likely the problem is because you're running as root, and NPM disables scripts automatically when you do that. Try passing the --unsafe-perm to the NPM install command
