Solution :-

You need to change ownership of node_modules, because you use sudo npm install -g node-sass so its ownership set to root,

To change ownership to current user as group -

sudo chown -R root:YOUR_USERNAME /usr/local/lib/node_modules/

sudo chmod -R 775 /usr/local/lib/node_modules/

And never use sudo for npm related query.

If you have not added node pakage.json yet try running node init if you already have this npm install node-sass. if both are present and you are using ubuntu try changing permission of the folder using chmod -R path to node module

I am working ionic and have this issue so I solved this by move one folder back and run command.

sudo chmod 777 -R project-directory

after this npm install node-sass --save

Try this

sudo npm install -g --unsafe-perm node-sass

Or this

sudo npm install -g --unsafe-perm --verbose @angular/cli
