My system configuration:

nvm 0.33.8 ,

npm 5.6.0 .
I want to install Angular-cli npm install -g @angular/cli.
But I get an error message:

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?
