Mobile Center CLI, "SyntaxError: Unexpected token" When Uploading Tests

How to solve this error that appears when using the Mobile Center Command-Line Interface to upload tests to Mobile Center?

SyntaxError: Unexpected token ...

This error appears because you have an earlier version of Node installed on your machine.

The Mobile Center CLI, mobile-center, requires the latest version of Node.

Here's the steps I used to fix this error:

1. Install HomeBrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. Update to the latest version of Node by entering these commands into your Terminal

   sudo brew uninstall node
   brew update
   brew upgrade
   brew cleanup
   brew install node
   sudo chown -R $(whoami) /usr/local
   brew link --overwrite node
   sudo brew postinstall node

3. Uninstall/Reinstall mobile-center-cli to ensure you have the most recent version of the Mobile Center CLI by entering these commands into your terminal

   npm uninstall -g mobile-center-cli
   npm install -g mobile-center-cli

4. Log into Mobile Center via CLI by entering this command into your terminal*

   mobile-center login

5. You are now able to upload your UITests to Mobile Center using the CLI

   mobile-center test run uitest --app [appname] --devices [deviceID] --app-path [LocationOfYourAppOnYour]  --test-series "master" --locale "en_US" --assembly-dir [FolderContainingUITestDLL]
