additional install instructions (root install with npm 6.8.0) about zero

[martinjackson]

This error appeared when attempting installing zero on WSL Ubuntu 18.04 (Windows Subsystem for Linux) on Windows 10. Is this a WSL only problem? Is this an npm 6.8.0 problem?

I think this can be resolved by adding an asterisk and footnote to the install section.

• Note: If you get an 'Error: EACCES: permission denied' (even as root), use npm config set unsafe-perm=true

Example:

sudo -i
npm config set unsafe-perm=true
npm install -g zero  

Problem:

sudo npm install -g zero
-- or --
sudo -i
npm install -g zero

Solution:

This isn't a bug. It's a giant security feature of npm. If you're bypassing this you're introducing security flaws and Zero absolutely should never, ever, recommend this incredibly dangerous behavior.

I think I looked into this and as far I remember Zero needs to install node-sass which needs to mkdir some folders in global npm directory (which is owned by root) but npm runs npm install with a different user (nobody I think).

So as of now, the least unsecure method to install zero globally under root is:
npm install --unsafe-perm -g zero

Is there a better way?

npm install -g zero

⚠️ Thus stuck at getting started 😞. How to proceed?

Was same here and followed Getting Started.

However, got unstuck by not using sudo. 🤩
