How to get npm or sass to install globally?-CodePudding

I've been watching tutorials and searching all over, and I've seen several similar issues on here. But none with the same errors. So I apologize if this has been answered before.

I'm taking a self-paced coding class. And I'm supposed to install sass. I finally found a tutorial that seemed straightforward. But when I entered the commands I'm getting error codes in my terminal. I'm very new to all this, so I have no idea what any of this means.

Some context: I downloaded homebrew, but didn't understand that either (so I uninstalled it). So then I Followed THIS tutorial where I downloaded node.js/npm. And everything went fine until I tried the install -g sass command. Then I started getting all these messages and going down the rabbit hole. Npmjs.com has some info on this issue, but I couldn't figure it out. It mentions reinstalling npm, or using "nvm". But when I tried the command npm install -g npm it returned very similar errors.

CodePudding user response：

you need admin access, using sudo should help you

sudo npm i -g sass

this means you have superuser access, and is required to install packages globally.
