Can't start Jazz midi in a raspberry

[autotel]

I am not very experienced in linux in general. I am developing an app targeted for raspberry, that would benefit of jazz-midi.
When I try to run the node module, I get the following error

Code: Select all

module.js:471
    throw err;
    ^

Error: Cannot find module './bin/6_9/'
    at Function.Module._resolveFilename (module.js:469:15)
    at Function.Module._load (module.js:417:25)
    at Module.require (module.js:497:17)

    at Module.load (module.js:487:32)
    at tryModuleLoad (module.js:446:12)
    at Function.Module._load (module.js:438:3)

running jazz-midi/test.js outputs the same error.

I unistalled jazz-midi and reinstalled it again, to be able to show you te installation output:

Code: Select all

 $ npm install jazz-midi

Perhaps from your guidance I could write a basic tutorial to make this install for other inexperienced raspberry users.

Raspberry PI is currently not supported, but that's a great idea for the future development.

good to know!
Well, indeed would have been nice for my current project.
thanks for the reply!

A new version uploaded to https://www.npmjs.com/package/jazz-midi
Tested with RPi 3 on node v6.x and up.

That is nice!
I tried it out now, and it has a problem where it requests the x server.
It will keep sending this output:

Code: Select all

PuTTY X11 proxy: unable to connect to forwarded X server: Network error: Connection refused
xcb_connection_has_error() returned true

**edit**
sorry, my bad: I was starting the SSH session with x11 forwarding. But I guess its a good curiosity for you to know

Oh, you scared me!
