Dependencies installed, but main.py throws errors

[Kabouik]

I installed asciimatics and keyboard using pip, ncurses is installed, but I can't run main.py regardless of the version of Python I use:

nemo@Sailfish nnn]$ devel-su pip install asciimatics

I tried as root, but got the same errors. Any ideas? Is it possible my version of ncurses is too old? I only have 6.1 available.

However your python was installed, by package or manually, It did not include or link with ncurses.

If you manually compile python, the configure script makes a report of modules that will not be built because ncurses/curses.h was not found, or perhaps, by manually compiling it, it will be found.

best wishes

Thanks for your answer. You are absolutely right, the repository version of python3 I initially had was built without ncurses, and this led to other applications failing to run, like glances for instance. However, I later found a community version which fixes that dependency and I could confirm that glances would then correctly run, but I am still getting the same issue in term-tris so I am not sure why it is not picking the updated python version like glances did.

[jquast]

You have more than one version of python installed, and term-tris was installed through the bad one. Try using the “which” command to locate the bad one,

which python
which pip
devel-su which python
devel-su which pip
which term-tris
which glances

Etc. when you find the location of the bad python interpreter, you can call into the pip module to uninstall term-this from it, and use the good python interpreter to install term-tris

/usr/local/bad/python -m pip uninstall term-tris

/usr/local/good/python -m pip install term-tris

[Kabouik]

Oh, maybe that is where the issue is then. I didn't install term-tris, I just cloned the repository and was trying to run python3 main.py after installing asciimatics and keyboard using pip.

I did try installing term-tris using pip before, but no matching version was found, which is why I tried cloning and running the executable. Perhaps there is no version compatible with arm devices?

[jquast]

You are right that term-tris is not on pypi, it is missing setup.py, too, so, the way you are running is fine.

but it should work fine on arm cpu as far as I can tell, anyway I’ve reached the end of my support contract lol, best wishes and good luck, “Tetris 99” is free on Nintendo switch with a Nintendo online account, I highly suggest that one, lol!
