Cannot read property 'toString' of undefined

[lawsonjt]

I'm on the first exercise and created program.js with console.log('HELLO WORLD') inside it.
In the terminal after running learnyounode I type learnyounode run program.js

Could not run: TypeError: Cannot read property 'toString' of undefined

Hi @lawsonjt

Could you solve the problem?
If not, can you give us details about node version and os you are using?
