Problem with permission installing node-sass

Question

I am trying to install node-sass in a create react app. I tried running:

sudo npm install node-sass --save

And I get the following error:

    Unable to save binary /Users/username/Desktop/code/advocado/node_modules/node-sass/vendor/darwin-x64-57 : { Error: EACCES: permission denied, mkdir '/Users/username/Desktop/code/advocado/node_modules/node-sass/vendor'
at Object.fs.mkdirSync (fs.js:885:18)

errno: -13,
code: 'EACCES',
syscall: 'mkdir',
path: '/Users/username/Desktop/code/advocado/node_modules/node-sass/vendor' }

This is followed by post install action:

node-sass@4.9.3 postinstall /Users/username/Desktop/code/advocado/node_modules/node-sass

This runs a lot more code, but for the sake of being concise I am not including it as the error is likely with the 'Error: EACCES: permission denied'

What is the permission that is being denied here and how can I approve it?

EDIT:

When I try running the same command (ie without sudo ):

npm install node-sass --save

I get the following warning:

npm WARN checkPermissions Missing write access to /Users/username/Desktop/code/advocado/node_modules/jest-cli
