bpython not running on win 10 despite installed curses

Question

so i went through the workaround in order to be able to run bpython on a windows 10 PC (64 bit, Python 3.10.2). installed the necessary curses from http://www.lfd.uci.edu/~gohlke/pythonlibs/#curses

installed bpython (pip install bpython)

and ran bpython-curses.exe. I still get the long error ending with " from fcntl import ioctl ModuleNotFoundError: No module named 'fcntl'"

Any ideas?

Answer 1

pip install -U windows-curses bpython

Then comment/remove lines 35 and 221 from %APPDATA\..\Local\Programs\Python\Python38\Lib\site-packages\bpython\args.py or similar location. Those will be the lines with the string curtsies in them, (see below for sample).

Then run

bpython-curses

Problem Solved

Technical details...: args.py:

import argparse
from typing import Tuple, List, Optional, NoReturn, Callable
import code
# import curtsies  ### REMOVE
import cwcwidth
...
    logger.info("Python %s: %s", sys.executable, sys.version_info)
    # versions of required dependencies
    #  logger.info("curtsies: %s", curtsies.__version__)  ### REMOVE
    logger.info("cwcwidth: %s", cwcwidth.__version__)
