Can't start DevTools from VS Code: Dart DevTools exited with code 66 #2398

Hi there,
I get "code 66" error when trying to start DevTools from VS Code. Here's my log:

I followed the steps in #2128 and deactivated then reactivated devtools. What I noticed though was that it's looking for the pubspec.yaml file in ~/.pub-cache/hosted/pub.dartlang.org/devtools-0.2.3 but the directory ~/.pub-cache/hosted does not exist.
I did have issues with my flutter environment a while back, and may have removed ~/.pub-cache/hosted to fix my dependencies, but I can't remember for sure. It was a long day and my caffeine levels were dangerously low!
Any idea on how I could fix this? Thanks!
