Particle-CLI fails after update: SyntaxError: Unexpected token [SOLVED]

Troubleshooting
1

I’m was having trouble compiling my project in Particle Dev after changing to V2 folder structure so I figured I’d try compiling in command line to see more verbose data. My version of Particle-CLI didn’t seem to understand V2 format (missing libraries) so I updated it, and now I’m getting the following errors when simply running Particle from the command prompt.

I deleted the folders from …/AppData\Roaming\npm\node_modules and reinstalled particle-CLI but I get the same errors. Any suggestions?

I uninstalled and re-installed Node.js and that solved the problem. Apparently I was still using an ancient version.
