What versions of Python and pip you are using?

[gotcha1]

Python 2.7.16 (32bit)
pip 19.1.1

[Tattoo]

Ok, those seem reasonable.

IHL depends on pyautogui which, in turn, seems to depend on pygetwindow.

It seems pygetwindow broke backwards-compability to Python 2.

I'm not in front of computer for a while so I cannot test, but workaround could be installing older version of pygetwindow, and then pyautogui, then IHL:

$ pip install pygetwindow==0.0.4
$ pip install pyautogui 
$ pip install robotframework-imagehorizonlibrary

If this works, could you confirm in this issue so, thanks

[gotcha1]

pip install pygetwindow==0.0.4 --> passed
but pip install pyautogui and pip install robotframework-imagehorizonlibrary failed with same error :

[Tattoo]

which command gives you this? please provide entire output. also, have you uninstalled what you had before running these installation steps?

[gotcha1]

Yes uninstalled existing pygetwindow and then isntalled pygetwindow--> passed.

pip install pyautogui--> failed with below error:

As I said in the previous message, you need to uninstall everything, then try installing one at a time.

These are not either the full command output one gets in command prompt/terminal. Please provide those.

Uninstall python 2.7 and robot framework also?

I had similar issue. I was able to install using pygetwindow 0.0.1 and pyscreeze 0.1.18

[Tattoo]

Just as I suspect:
Collecting pygetwindow>=0.0.5 (from pyautogui>=0.9.30)

So you need to use older version of pyautogui that accepts older version of pygetwindow.

Based on release history and version control, last such version was 0.9.42, so once more :

• uninstall all three packages in question
• pip install pygetwindow==0.0.4
• pip install pyautogui==0.9.42
• pip install robotframework-imagehorizonlibrary

@Tattoo Thanks a lot! followed above suggestion and it worked.
