Build piston from scratch - how to install runtimes?

[rizal-rovins]

Hey guys,
I'm trying to build piston from scratch , my purpose is to make some modifications and install additional libraries.

1. I first clone the repo,
2. install the dependencies : cd cli && npm i && cd -
3. Start the build : ./piston start
4. I can see now that my server is running but it has no runtimes.
5. cli/index.js ppman list > when i run this , it returns empty
6. cli/index.js ppman install python > when i run this , Requested package python-* does not exist

I'm not able to install any packages, what am i missing here?

Okay, I figured it out.
I had to build packages first using :
./piston build-pkg python 3.9.4

You can do ./piston select prod to run on the production environment and you wouldn't need to build the packages. You would just install them.
