Cannot generate scaffold per crash course

Trying to get up to speed with compound by following the crash course.

1. npm init todo-list-app: works
2. npm install (inside todo-list-app): works, with complaints about old versions of jade, minimatch, graceful-fs
node-uuid
3. compound generate scaffold list name (inside todo-list-app, with the back tics): fails. "bash: exists: command not found"

There doesn't seem to be an OS binary named exists, so I did an npm install -g exists and repeated above steps. Same error at #3.

The issue is about the 'compound generate scaffold' command failing with 'exists: command not found'. Start by examining the compound CLI tool's scaffold generation script, likely in a bin/ or lib/ directory. Check how it invokes the 'exists' command and whether it's a missing dependency or a path issue. Running the command in debug mode or checking the project's package.json for scripts and dependencies will help. 'Done' is when the scaffold command runs without the 'exists' error.
