I would like to use a Python script to create a video from Stellarium. I have tried several different methods, but so far none have worked. A promising approach is to spawn Stellarium and then use pyautogui to take a screenshot, then kill Stellarium and increment the variable which will change the point of view and run Stellarium with the new command line.

The problem is, I cannot install pyautogui.

Here is the relevant code:

import os import subprocess import pyautogui import time # Set the path to Stellarium and FFmpeg stellarium_path = "/usr/bin/stellarium" # Adjust as necessary ffmpeg_path = "/usr/bin/ffmpeg" # Adjust as necessary # Create a directory to store images output_dir = "/RAID/Server-Main/FlatEarth/Stellarium Screen Shots/Video" os.makedirs(output_dir, exist_ok=True) def capture_images(object_name, field_of_view, start_latitude, end_latitude, longitude, date, dtime): # Loop through the specified latitude range for latitude in range(start_latitude, end_latitude + 1): # Prepare the Stellarium command command = f'"{stellarium_path}" --full-screen=no --longitude={longitude} --latitude={latitude} --fov={field_of_view} --object={object_name} --sky-date={date} --sky-time={dtime}' # Execute the Stellarium command print(f"Capturing image at Latitude: {latitude}") GuiProc = subprocess.popen(command) # Wait for a moment to ensure Stellarium has time to process time.sleep(5) # Take a screenshot screenshot = pyautogui.screenshot() # Save the screenshot screenshot.save(f'"{output_dir}/image_lat{latitude}.png"') # Kill Stellarium GuiProc.terminate

When I try to load pyautogui I get:

error: externally-managed-environment This environment is externally managed To install Python packages system-wide, try apt install python3-xyz, where xyz is the package you are trying to install. If you wish to install a non-Debian-packaged Python package, create a virtual environment using python3 -m venv path/to/venv. Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make sure you have python3-full installed. If you wish to install a non-Debian packaged Python application, it may be easiest to use pipx install xyz, which will manage a virtual environment for you. Make sure you have pipx installed. See /usr/share/doc/python3.11/README.venv for more information. note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages. hint: See PEP 668 for the detailed specification.

I tried all the methods recommended by the above error code to no avail. I also tried pip3 install brew so I could possibly use it to install pipx, but I get the same error.

Then I tried

python3 -m venv ~/myenv source ~/myenv/bin/activate pip3 install pyautogui

and it says:

Requirement already satisfied: pyautogui in /root/my_envs/lib/python3.11/site-packages (0.9.54) Requirement already satisfied: python3-Xlib in /root/my_envs/lib/python3.11/site-packages (from pyautogui) (0.15) Requirement already satisfied: pymsgbox in /root/my_envs/lib/python3.11/site-packages (from pyautogui) (2.0.1) Requirement already satisfied: pytweening>=1.0.4 in /root/my_envs/lib/python3.11/site-packages (from pyautogui) (1.2.0) Requirement already satisfied: pyscreeze>=0.1.21 in /root/my_envs/lib/python3.11/site-packages (from pyautogui) (1.0.1) Requirement already satisfied: pygetwindow>=0.0.5 in /root/my_envs/lib/python3.11/site-packages (from pyautogui) (0.0.9) Requirement already satisfied: mouseinfo in /root/my_envs/lib/python3.11/site-packages (from pyautogui) (0.1.3) Requirement already satisfied: pyrect in /root/my_envs/lib/python3.11/site-packages (from pygetwindow>=0.0.5->pyautogui) (0.2.0) Requirement already satisfied: Pillow>=9.3.0 in /root/my_envs/lib/python3.11/site-packages (from pyscreeze>=0.1.21->pyautogui) (11.3.0) Requirement already satisfied: pyperclip in /root/my_envs/lib/python3.11/site-packages (from mouseinfo->pyautogui) (1.9.0)

The result /root/my_envs/lib/python3.11/site-packages (0.9.54) is certainly interesting, but it still says:

Traceback (most recent call last): File "/RAID/Server-Main/FlatEarth/Stellarium Screen Shots/./linux_lat_scan.py", line 5, in <module> import pyautogui ModuleNotFoundError: No module named 'pyautogui'

What should I try next? I'm running Debian Linux Bookworm

--break-system-packages

This can potentially break your system packages. Only use if you understand the risks.

Use it only in your venv.

pip3 install pyautogui --break-system-packages

Or try to use

pipx

pipx install pyautogui

Pipx bypasses the current limitations of Pip by simplifying the installation of Python packages in virtual environments. Pip is a popular tool for installing Python packages and modules from the Python Package Index.

  • As I thought I mentioned quite clearly in my original question, attempting to load pipx results in precisely the same issue as attempting to load pyautogui. I definitely do not understand all the ramifications of the situation and I do not understand why in what I think is the virtual environment its says everything is there - I think - but still does not work. Python frequently leaves me shaking my head, and this case is no example. Commented Sep 11 at 2:50
  • That's the problem with Python and all the package versions. It always annoys me too, and the fact that you can't just simply move a venv because of the hardcoded path. Have you checked out all the links? There are various solutions available. Commented Sep 11 at 9:11
