All is see are warnings!

PS, what version of NodeJS are you using (you can run `node --version` to find out)

In current NPM, `--unsafe-perm` is now deprecated and can be omitted.

BTW, for me (when on Windows), NPM only runs when in an administrator cmd-line.  
but maybe that is just how my PC is configured

That is a poor configuration. My installation of node.js does not behave that way. Even for npm global installs.

Worth noting that some fairly drastic changes will be landing in npm I believe, especially for v12(?). They are really strengthening the security settings.

Sorry, took these as errors and thought the install did not continue. As Steve said they are warnings and it does actually install. It installed so fast on my computer i thought it dumped out. Thank you all for taking the time to reply. I appreciate it very much.
