You are aware that bitcore is not Bitcoin Core, yes?

**UPDATE:**  Apparently the problem is because Mac OS doesn't support the library libunwind...      https://stackoverflow.com/questions/27842377/building-libunwind-for-mac#27853419 -- but I assume there's gotta be a viable workaround.  Surely all us Mac folks aren't forced to set up virtual boxes just to use Bitcore.io?

# Installation problem with Bitcore.io on Mac

(Asked by: username_0 on 2019-01-14)

I'm normally not too brain-dead about this stuff, but I've been unable to force this one through. I'm trying to install Bitcore (per their [instructions here](https://bitcore.io/guides/full-node)) but and have set **nvm** to the LTS version 4, as directed (v4.9.1), but when I run **npm install -g bitcore** it pukes at me:

```
/Users/evilg/.nvm/versions/node/v4.9.1/lib/node_modules/npm/bin/npm-cli.js:85
      let notifier = require('update-notifier')({pkg})
      ^^^

```

For what it's worth, my **npm** version is 6.2.0.

Any help much appreciated!
