当我跑步时

sudo pip3 install PyAutoGUI

我收到以下错误

[root@localhost Projects]# sudo pip install pyautogui 
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip install --user` instead.
Collecting pyautogui
  Using cached PyAutoGUI-0.9.36.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-build-ywXbn7/pyautogui/setup.py", line 6, in <module>
        version=__import__('pyautogui').__version__,
      File "pyautogui/__init__.py", line 115, in <module>
        from . import _pyautogui_x11 as platformModule
      File "pyautogui/_pyautogui_x11.py", line 7, in <module>
        from Xlib.display import Display
    ImportError: No module named Xlib.display

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-ywXbn7/pyautogui/

我通过安装 Pillow and Display 并仅使用 pip 命令遵循了其他故障排除建议。

我也尝试通过从 GitHub 克隆包并以这种方式安装 PyAutoGUI，但是返回以下错误消息：

[root@localhost Projects]# git clone https://github.com/asweigart/pyautogui

    raise error.DisplayConnectionError(self.display_name, r.reason)

我正在按照 Automate the Boring Stuff 第 18 章中的说明进行操作，并稍微修改了命令以适合 Fedora 27 Workstation。

【解决方案1】：

这个答案在 Fedora 30 上测试过。

首先安装依赖项

sudo dnf install scrot
sudo dnf install python3-tkinter
sudo dnf install python3-devel.x86_64

然后用 pip 安装 PyAutoGUI（不用 sudo/root）

pip3 install --user python3-xlib
pip3 install --user pyautogui

注意： PyAutoGUI 似乎需要 X，这在 Ferodra 30 中不是默认的，但可以在登录屏幕上选择。寻找 Xorg。

（旁注：安装软件时，建议使用sudo，如果是root登录，则不需要sudo）
