Permissions Issue when installing expo-cli

Hi,

I followed the steps on expo to first download node v12.2.0. Right after that I tried installing the expo client by entering ‘sudo npm install expo-cli --global’ into my terminal. Unfortunately, I’ve been getting permissions issues and the installation is unsuccessful every time.

Dunno what might be wrong. But here are two suggestions from SO:

  1. Make sure you’re using the correct npm (as sudoer). That is, maybe your npm isn’t installed in /usr/local/bin; maybe it’s in /usr/bin as like this post: https://stackoverflow.com/questions/44198721/getting-permission-error-while-trying-to-install-angular-cli
  2. Try using --unsafe-perm. I forget what issue I was having myself recently, but that did the trick when installing globally as root; sometimes the UID gets set to the nobody user and fails. See, for example, this post: https://stackoverflow.com/questions/52231289/gyp-err-stack-error-eacces-permission-denied-mkdir-var-www-project-name-no
