mido在 Ubuntu 18.04 上，我正在尝试创建一个安装了模块的 conda 虚拟环境keyboard。这是使用conda create -n my_env python=2.7and pip installfor midoand成功完成的keyboard。当我从 conda 虚拟环境中运行 python 然后键入import mido和import keyboard.

问题是当我尝试运行我在单独线程中编写的keyboard.on_press(keyboard_thread)调用keyboard_thread函数时，我收到此错误：

Traceback (most recent call last):
  File "my_code.py", line 361, in <module>
    keyboard.on_press(keyboard_thread)
  File "/home/hany/miniconda3/envs/conda_sika/lib/python2.7/site-packages/keyboard/__init__.py", line 474, in on_press
    return hook(lambda e: e.event_type == KEY_UP or callback(e), suppress=suppress)

    raise ImportError('You must be root to use this library on linux.')
ImportError: You must be root to use this library on linux.

我尝试运行sudo python my_code.py，没有错误出现 keyboard.on_press(keyboard_thread)，但随后import mido返回ImportError: No module named mido

有没有办法让我有一个虚拟环境可以让两个模块正常运行？

我感谢您的帮助。
