Can't install on mac

When trying to install it throws permission error. Even when tried installing by becoming root then also getting error of the following form:-
gyp WARN EACCES user "root" does not have permission to access the dev dir "/usr/local/lib/node_modules/terminalizer/node_modules/node-pty-prebuilt/.node-gyp/8.11.4" gyp WARN EACCES attempting to reinstall using temporary dev dir "/usr/local/lib/node_modules/terminalizer/node_modules/node-pty-prebuilt/.node-gyp"

You need to fix the permissions

chown -R faressoft /usr/local/lib/node_modules
chown -R faressoft /usr/local/bin
chown -R faressoft /usr/local/share

Change faressoft to your username.

Still getting the same error.

Please execute and give me the results of

ls -l /usr/local/lib/node_modules/terminalizer
ls -ld /usr/local/lib/node_modules/terminalizer
ls -ld /usr/local/lib/node_modules
ls -ld /usr/local/bin
ls -ld /usr/local/share

You could try this nodejs/node-gyp#454 (comment)

sudo npm install --unsafe-perm --verbose -g sails

When installing with sudo.

As for the reason an install currently won't work for you without a sudo is because it is trying to add global packages to /usr/local/lib/... and most operating systems will have permissions set to root for these folders.

If you are getting started with npm I would suggest you try and read this https://docs.npmjs.com/getting-started/fixing-npm-permissions (and the entire getting-started wiki for that matter) it talks about the NPM_CONFIG_PREFIX environment variable which allows you to set a custom global install path, preferably at your user's home folder (~ or /Users/$USER) this way you will not need sudo to install global packages.
