键盘和弦代码的错误消息：termios.error: (25, 'Inappropriate ioctl for device')

Question

I'm a python beginner, and I was recently trying to code a program that required the readchar module. However, I kept getting the error message:

termios.error: (25, 'Inappropriate ioctl for device')

I've tried adjusting my code, but I keep getting the same error message. Here is my code:

import readchar

while True:
    print(readchar.readkey())

(This is the full error message.)

Traceback (most recent call last):
   File "/Users/larajean/PycharmProjects/thegreatesthits/chordKeyboard.py", line 7, in <module>
chord = readchar.readkey()
   File "/Users/larajean/PycharmProjects/thegreatesthits/venv/lib/python2.7/site-packages/readchar/readchar.py", line 20, in readkey
c1 = getchar()
   File "/Users/larajean/PycharmProjects/thegreatesthits/venv/lib/python2.7/site-packages/readchar/readchar_linux.py", line 12, in readchar
old_settings = termios.tcgetattr(fd)
termios.error: (25, 'Inappropriate ioctl for device')

I am using a PyCharm IDE and a version of Python 2.7. Any suggestions on how to fix this problem?

You need to enable Emulate terminal in output console setting in the run configurations section of PyCharm to make it compatible with termios .

To get there, either right click in the file editor then click Modify Run Configuration...

Or go to the menu bar > Run > Edit Configurations

Then in the Execution section, enable the Emulate terminal in output console setting and apply.
