在while循环中使用pythoninquirer在命令行上创建复选框时出现错误：（25，“ioctl for device”）错误

Question

我试图在while循环中使用pythonqueryr创建checkbox。 我的代码如下：

import inquirer
count = 5
while count > 1:
    questions = [inquirer.Checkbox('interests',
                                   message="Yes or no",
                                   choices=['Computers', 'Books'],)]
    answers = inquirer.prompt(questions)
    print(answers['interests'])
    count -= 1

但是我得到了一个错误-（25，“设备的ioctl不合适”） 我正在附加堆栈跟踪：
