ValueError: invalid literal for int() with base 10: ''

First of all, thank you so much for your work on this project.

I'm receiving this error on Ubuntu 22.04. I download and extract a binary build of my script (which uses simple-term-menu) from here. When I run it though, I get the follow error:

tput: /tmp/_MEIRdZD9q/libtinfo.so.6: version `NCURSES6_TINFO_6.2.current' not found (required by tput)
Traceback (most recent call last):

  File "simple_term_menu.py", line 885, in _num_lines
ValueError: invalid literal for int() with base 10: ''

The weird thing is, if I run the same binary-building commands locally on my Ubuntu VM, the binary works perfectly fine. Any ideas what the error could be?

Hey and thanks for using simple-term-menu :smile:. Line 885 uses the tput command to get the height of the terminal, but tput in your build does not match the installed ncurses version (NCURSES6_TINFO_6.2.current' not found). I would guess that ncurses is missing on the test system.

Yup thank you, that's what it turned out to be. I've got some weird things going on with that ubuntu instance 😅 I tried it on another instance and it worked.
