尝试在Colab中导入pyatogui时，为什么会出现此错误？

Question

!sudo apt install tesseract-ocr

!pip install pytesseract

!pip install pyinstaller

!pip install pyautogui

!pip install pillow

!pip install python3_xlib python-xlib

这就是我第一个单元格中的东西。

然后，当我尝试导入pyautogui时，它显示此错误：

ConnectionRefusedError                    Traceback (most recent call last)
/usr/local/lib/python3.6/dist-packages/Xlib/support/unix_connect.py in get_socket(dname, protocol, host, dno)
    118             try:
--> 119                 s = _get_unix_socket(address)
    120             except socket.error:

10 frames
ConnectionRefusedError: [Errno 111] Connection refused

During handling of the above exception, another exception occurred:

ConnectionRefusedError                    Traceback (most recent call last)
ConnectionRefusedError: [Errno 111] Connection refused

During handling of the above exception, another exception occurred:

    125                     raise
    126     except socket.error as val:
--> 127         raise error.DisplayConnectionError(dname, str(val))
    128 
    129     # Make sure that the connection isn't inherited in child processes.

DisplayConnectionError: Can't connect to display ":0": [Errno 111] Connection refused

我想这与colab无法连接到我的计算机有关，但我不知道。
