Having a problem with npm global install on MacOS 11.6.1 with M1 chip

Question

I'm trying to install npm in the terminal and I keep getting err messages.

The command is

`npm install -g ts-node` 

and this is the err return

npm ERR! code EACCES
npm ERR! syscall symlink
npm ERR! path ../lib/node_modules/ts-node/dist/bin-script-deprecated.js
npm ERR! dest /usr/local/bin/ts-script
npm ERR! errno -13

npm has an entire web page specifically on how to resolve the issue of EACCES errors when installing packages globally . Find all the details there. They suggest many possible solutions. The one I would recommend, especially since you are presumably having this issue on a development machine, is to use a version manager like nvm instead of whatever package or whatever you used to install Node.js on your machine. But check the aforementioned web page for other options.
