ImportError PyBoy on termux

I tried to test my work on my phone using Termux Debian emulator. After uninstalling the pyboy module and cloning my repository, I get an import error inside your module. I don't understand what is wrong.
[Thank you]

Isn't this expected with pyboy being uninstalled? I think you should at least install it via for it to work

Ohh, for full context please check my issue on GitHub https://github.com/Baekalfen/PyBoy/issues/401
I need to use the source code without CPython
in order to directly control pyboy.mb

how to execute 1 processor instructions · Issue #401 · Baekalfen/...

Hello, I have a question: why doesn't the PyBoy class have a method that performs just one CPU step/instruction? I wanted to build my own basic emulator and decided to create a test by comparin...

While making some failed tests for the link-cable serial connection, I ended up editing the cython declaration to expose the whole mb and perform one instruction at a time with a new method, basically running two equal instances of the same game in sync one instruction at a time

But yeah, it's also possible to use the hook method to make an abstraction of that and do a "run_until_hook()" function that returns in a way similar to tick(), with functions that just sets a bool exit condition

Thank you for the response on issue 401,
but we've moved away from the context of issue 403.
I have already found a way to do single instruction stepping.
The problem is that module import doesn't work in Termux (Debian).
See the trace in issue 403.

I think your problem is a generic Python issue. You're importing a module that you have not installed, and it is not in your path. You placed it in a subdirectory, while you are executing Python somewhere else

I double-checked the run on my laptop,
and yes, the same error occurs.
I thought I made a commit when everything was working.
Alright, I will figure it out.
Thanks.
