Package install failed, see above.

Tried clearing cache, and running the command again. doesn't work.
Tried the following steps, but didn't work:

deleting npm , npm-cache folders from C:\Users\Username\AppData\Roaming
2)uninstall node js
reboot
4)install again
reboot
run command "npm install -g @angular/cli"
reboot
run command "ng new firstproj" gives the same error. "cb() never called".
Is there any solution for this?
