import pwn 在 PyCharm 中崩溃，但在运行来自终端时有效

Question

当我尝试运行 PyCharm 中的行 import pwn 时，它崩溃并显示以下错误消息：

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

    s = curses.tigetstr(cap)
_curses.error: must call (at least) setupterm() first

Process finished with exit code 1

但是，当我从终端执行文件时，运行没问题。

我试图找到类似的问题，但似乎其他人的错误是 ImportError: cannot import name ENUM_P_TYPE 而不是我的错误。

我运行在 macOS 10.15.4 上安装这个。

问题是由于这个 Warning: _curses.error: setupterm: could not find terminfo database，导致 curses 抛出错误和异常。

解决办法应该是导出终端变量

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

但对于pycharm，需要在pycharm的配置中完成。

基于this answer，应该从Edit Configurations -> Environment variables开始设置，设置名称值对

TERM linux

TERMINFO /etc/zsh
