From what I know this library is only used within Conveyal for Conveyal projects.

What project are you using it for? What command are you running exactly?

Hi.
I am trying to install Conveyal Transit Data Tools which requires Mastram.

What I tried to do in later steps is to go inside cloned github repository folder and tried to initiate a build with the command mastarm build: C:\Users\Omistaja\Documents\GitHub\datatools-ui>mastarm build

Aftterwards I got the following error:
`Without "from" option PostCSS could generate wrong source map and will not find Browserslist config. Set it to CSS file path or to "undefined" to prevent this warning.
events.js:183
throw er; // Unhandled 'error' event

I have decided to like solve one error at a time to see where it leads to.
But thought of seeking suggestions from you.
