Installing npm live-server on MacOS Catalina

Question

I'm trying to install npm live-server but I am getting the following errors:

stl34>>npm install live-server -g

The issue seems to be that the file permissions for /usr/local/lib/node_modules need to be changed. I tried restarting in recovery mode and typing into the terminal:

csrutil disable

to disable SIP. Then I restarted and entered the following into the terminal:

sudo mount -uw /

chmod 775 usr/local/lib/node_modules

But the system still will not allow me to modify the file permissions. What can I do to modify them?

Another user asked this same question here: NPM Live-server not installing on zsh but received no answers.

Answer 1

running "sudo npm install live-server -g" worked for me
