terminfo database problem

[Jan Pipek]

Hi, your project sounds quite interesting. So I pip-ed it and tried with the simplest command possible:

maybe rm filename

However, what I received, was an error message:

Traceback (most recent call last):
  File "/home/username/anaconda3/bin/maybe", line 7, in <module>
    from maybe.maybe import main
  File "/home/username/anaconda3/lib/python3.4/site-packages/maybe/maybe.py", line 23, in <module>
    from .syscall_filters import SYSCALL_FILTERS

    self._init_descriptor)
_curses.error: setupterm: could not find terminfo database

Do you know what could be source of the problem?
Thanks,
Jan

P.S. Anaconda distribution, Python 3.4.3, Linux (Fedora 22)

A quick web search shows this to be a common issue, and the "fix" apparently consists of setting your TERM environment variable to xterm-256color.

I use Fedora myself so the root cause is likely Anaconda or your terminal. Perhaps Anaconda clears the TERM variable for some reason? Many terminal emulators (including GNOME Terminal, but not Guake) set xterm-256color already, so this should not be necessary unless something overwrites the terminal default.

Thanks.

Strangely enough, I upgraded Anaconda to Python 3.5 in the meantime (for other reasons) and the problem disappeared. I have (and probably did have) the TERM set correctly. So the distribution's fault?

Anyway, it works. So as far as I am concerned, you can close the issue :-)
