Running Node (or any unix cmd line program) from Shell from a LC Stack

LiveCode will inherit the path env variable given to it by the environment which launched it.

If you have access to exes from Terminal in something like /usr/local/bin but not from apps launched from the desktop then this suggests the local bin path is only configured in your bashrc rather than truly globally.

I'm pretty sure there is a way to configure global env vars on Mac although not sure where it would be these days...
