How does PyInstaller manage to create and EXE file when the python script is consisted of proprietary module?

Question

Hi I have a script that I want to turn into an EXE file so that I could you use it out of my Development Environment. This script is utilizing proprietary modules that are based on selenium (in my case firefox webdriver). I have converted the script (CFP2_Recovery.py) into an EXE file by using PyInstaller. The result of this conversion looks good:

I copied the whole contents of the script conversion to the other station and tried to run it. The script almost immediately failed and I believe that it was during the part where selenium and my private libraries are getting involved. This is the result of me trying to run the EXE file:

During handling of the above exception, another exception occurred:

[3040] Failed to execute script CFP2_Recovery

I don't see what is the problem exactly but one of the lines in the error message got my eye. The one that tells that " 'geckodriver' executable needs to be in PATH ". geckodriver (firefox webdriver) is actually in PATH of the development station. Should I also puy it in PATH of the station that I am trying to run (EXE file) it from ? Am I missing something in the process of the EXE file creation ?

Answer 1

Do you have something like this in your code:

browser = webdriver.Firefox(executable_path=r"geckodriver-v0.19.1-win64\geckodriver.exe")

Maybe you could package the geckodriver in your install path.
