npm install aurelia-cli -g installs 26 not 25 and neither 25 nor 26 are working on Ubuntu

I’m submitting a bug report

• Library Version: 25.0.0
  26.0.0

Please tell us about your environment:

• Operating System: Linux (Ubuntu 16.04 LTS)

• Node Version: 4.2.6

• NPM Version: 3.10.9

Current behavior:

• After using npm install aurelia-cli -g it installed, 0.26.0 not 0.25.0 (I had 0.24.0 before and thought it will install 0.25.0 as it was mentioned as the latest version
• I’m not able to use any ‘au’-commands
• when installing either 0.25.0 or 0.26.0 globally and running for example ‘au -v’, I’m getting this:

au -v
/usr/local/lib/node_modules/aurelia-cli/lib/file-system.js:70
exports.join = function(...segments) {
                        ^^^

SyntaxError: Unexpected token ...

    at Module._compile (module.js:410:26)
    at Object.Module._extensions..js (module.js:417:10)

• In both cases I did used a fresh install by using npm uninstall aurelia-cli@0.25.0 -g

Expected/desired behavior:

• Being able to use any ‘au’-commands at all
• Installing Version 0.25.0 while using npm install aurelia-cli -g (why am I on a different release channel?)

Thanks for helping me

@TonySpegel, you will get that issue if you’re not running higher than node 5 (pretty sure it needs to be the LTS or greater, or at least around 6). Something about being able to use ES6 features (like the ... spread operator).
Upgrade your node version first. Then, try these following commands (exactly, just copy paste) to ensure that you’ve cleaned and re-installed the latest aurelia cli npm uninstall -g aurelia-cli au npm cache clean npm install -g aurelia-cli

I’m going to go ahead and close this issue for now, as the CLI has needed to be running >=6 for a while. If we need to support previous versions, let’s make that a separate issue.
