Setupterm could not find terminal, in Python program using curses

I am trying to get a simple curses script to run using Python (with PyCharm 2.0).

This is my script:

import curses
stdscr = curses.initscr()
curses.noecho()
curses.cbreak()
stdscr.keypad(1)
while 1:
    c = stdscr.getch()
    if c == ord('p'): print("I pressed p")
    elif c == ord('q'): break

curses.nocbreak(); stdscr.keypad(0); curses.echo()
curses.endwin()

When I run this from my IDE (PyCharm 2) I get the following error:


_curses.error: setupterm: could not find terminal
Process finished with exit code 1

If I run the script from bash it will simply be stuck in the while loop not reacting to either pressing p or q.

Any help would be appreciated.

You must set enviroment variables TERM and TERMINFO, like this:

export TERM=linux
export TERMINFO=/etc/terminfo

And, if you device have no this dir (/etc/terminfo), make it, and copy terminfo database.

For "linux", and "pcansi" terminals you can download database:

Go to run/debug configuration(the one next to Pycharm run button). Sticking on Emulate Terminal In Output Console. Then you will be able to run your program with the run button.

I found this question when searching for examples because I am also learning to use curses so I don't know much about it. I know this works though:

import curses
try:
    stdscr = curses.initscr()
    curses.noecho()
    curses.cbreak()
    stdscr.keypad(1)
    while 1:
        c = stdscr.getch()
        if c == ord('p'):
            stdscr.addstr("I pressed p")
        elif c == ord('q'): break
finally:
    curses.nocbreak(); stdscr.keypad(0); curses.echo()
    curses.endwin()

I also added the try: finally: to make sure I get the terminal to it's original appearance even if something simple goes wrong inside the loop.

You have to use the addstr to make sure the text is going to be displayed inside the window.

I was having the same problem. See Curses Programming with Python - Starting and ending a curses application.

There's a curses.wrapper() function that simplifies the process of starting/ending a curses application.

Here's the example from the Python doc:

from curses import wrapper

def main(stdscr):
    # Clear screen
    stdscr.clear()

    # This raises ZeroDivisionError when i == 10.
    for i in range(0, 11):
        v = i-10
        stdscr.addstr(i, 0, '10 divided by {} is {}'.format(v, 10/v))

    stdscr.refresh()
    stdscr.getkey()

wrapper(main)
