Document how to install lilv python dependency

[jhordies]

Hello,
The app seems great but I can't get it to run.
I installed all the dependencies, I'm no expert in python, it seems that I'm still missing the lilv python bindings.
How did you get them to work?
Thanks

Hi!! I think it comes with lilv package. Do you have it on your system?

Unfortunately it doesn't. I installed lilv tools and lilv dev, I have the command lines tools working. But python complains the module is missing. I'm using an Ubuntu based distribution friendly core ( nano pi neo 3)

Oh, I Will try tonight in arch . I remember back then that I had to compile serd and sord and lilv to make lilv work on Ubuntu. But it was a few years ago. Does lv2ls or similar tools work?

[ajboni]

I tried and in my case I was missing the python-jack-client package, added it as a dependency in readme. Maybe that is what you are missing. sudo pacman -S python-jack-client . Also found a typo which was trying to use the upstream library.

Thanks, seems like python bindings for lilv are not installed , I don't know much about ubuntu to give you a proper answer unfortunately :(

[madorian]

Has this project been packaged for any distro? I'm trying to make a nix file for it.

Hi, no unfortunately not and I lost track of the deps needed, just tried it in arch and got it to run but cannot add plugins. (updated readme with python-lilv dependency. might need to do some research and update docs . If you find anything please let me know!
