如何在Fedora 27上安装PyAutoGUI

Question

When I run

sudo pip3 install PyAutoGUI

I receive the following error

[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:

    ImportError: No module named Xlib.display

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

I have followed other troubleshooting advice by installing Pillow and Display and using just the pip command.

I have also attempted installation of PyAutoGUI by cloning the package from GitHub and installing that way, however the following error message is returned:

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

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

I am following the instructions from Chapter 18 of Automate the Boring Stuff with the commands slightly altered to suit Fedora 27 Workstation.

Answer 1

This answer is tested on Fedora 30.

First install dependencies

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

Then install PyAutoGUI with pip (without sudo/root)

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

Note: PyAutoGUI seems to require X, which is not default in Ferodra 30, but can be chosen at the login screen. Look for Xorg.

(Side note: When installing software, it is recommended to use sudo, if you are logged on as root, there is no need for sudo)
