Unable to run `npm run build` on Ubuntu 17.10

[JasoonS]

Hi

I'm getting the following error when I run: npm run build, npm run build:web or npm run build:native:

✗ npm run build                 

> reprocessing-example@ build /home/jasoon/Documents/adhara/test/reprocessing-example
> bsb -make-world

ninja: no work to do.

The same thing happened when I ran this command on this repo https://github.com/ekosz/reprocessing-example-flow-field (well after I capitalised Reprocessing in the bsconfig.json).

@JasoonS Mmnmhm do you have OCaml installed globally? If so do you need it to be? Because it seems like it might be a different version than the one bsb-native uses and it seems to interfere...

If you don't need it you should try to remove it all and reinstall. This package comes with everything you need.

[JasoonS]

@bsansouci I do, I'll try remove it and let you know how that goes. Thanks for the help.

Working perfectly :)

Initially got a /usr/bin/ld: cannot find -lasound error, but a simple sudo apt install libasound2-dev solved that.

Would it be useful for me to add this to some kind of trouble shooting section?

@JasoonS Great! No need to open an issue, that's the same as #7
