Can't resolve 'async_hooks'

[jkhoel]

• node v12.4.0
• npm 6.13.7

As soon as I include @pm2/io in my project, it fails to compile - giving me module-not-found:
Module not found: Can't resolve 'async_hooks' in 'C:\00 - Git\dcs-mdc-generator\node_modules\@opencensus\core\build\src\internal'

I've tried installing both async_hooks and @opencensus on its own npm i async_hooks @opencensus but seems to have no effect
