Python curses module missing

#1 Post by Kromitvs »

Hello

I'm using Debian 10.9, Buster and Python 3.7.3

And it seems curses module is missing.

Code: Select all

python3
Python 3.7.3 (default, Apr 20 2019, 16:08:10) 
[GCC 6.3.0 20170516] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import curses
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.7/curses/__init__.py", line 13, in <module>
    from _curses import *
ModuleNotFoundError: No module named '_curses'
Is this a configuration issue?

Why do you have GCC 6.3 from 2017, you should have atleast GCC 8.3 ?

Maybe you have not updated your system properly.

Probably purge python3 and then reinstall python3.

Re: Python curses module missing

curses is part of standard Python, so it is in `libpython3.7-stdlib`. But this package is mandatory for Pyhton, so it is already installed.

Really at a loss here.

EDIT: reinstalled every python3 package.


This doesn't happen in your machines?

Re: Python curses module missing

I had run pip as root, so I was running a mixed installation of '/usr/local/' (not default debian) and '/usr/bin/python'.

What hinted that was the result of

Code: Select all

print(sys.path)
showing results in /usr/local

To fix it I rename the folder/usr/local/python3 to /usr/local/python3.old and run

Code: Select all

aptitute reinstall ~ipython3
