import pwn 在 PyCharm 中崩溃，但在从终端运行时有效

Question

When I try to run the line import pwn in PyCharm, it crashes with this error message:

/usr/local/bin/python3.8 /Users/ianzhang/Documents/Coding/CTF/buffer_overflow1.py
Warning: _curses.error: setupterm: could not find terminfo database

_curses.error: must call (at least) setupterm() first

Process finished with exit code 1

However, when I execute the file from the terminal, it runs fine.

I have tried to find similar questions, but it seems that other people have the error ImportError: cannot import name ENUM_P_TYPE rather than the error that I have.

I am running this on macOS 10.15.4.

Answer 1

The issue is due to this, Warning: _curses.error: setupterm: could not find terminfo database , leading to the curses throwing error and exception.

The solution should be to export the terminal variables

$ export TERM=linux
$ export TERMINFO=/bin/zsh

But for pycharm, it needs to be done inside pycharm's configuration.

Based on this answer , it should be set from Edit Configurations -> Environment variables and set the name value pairs.

TERM linux

TERMINFO /etc/zsh
