gyp ERR! configure error

[MokMec]

I just installed nodejs 10.16 and ionic.
When I try to run ionic serve on an empty project I get an error:"[ng] Error: Cannot find module "node-sass'"".

when I do sudo npm ls node-sass I get this:
ionicV3@0.0.1 /Users/m/Projects/ionicV3
└─┬ @angular-devkit/build-angular@0.13.9
└── 18 OPTIONAL DEPENDENCY UNMET node-sass@4.12.0

and when I do a sudo npm install -g node-sass I get the following error:

gyp ERR! configure error

Can someone help me?

Thank you
