Running pyinstaller another pc with Chromedriver


I am trying to add Chromedriver inside an executable in pyinstaller. While this is possible it seems that I get the below error message when trying to run this on another computer.

I have tried a number of posts including this one, but unfortunately, this has not provided desired results. Best case was I could run it on my own computer when chrome exe was in the same folder which was unhelpful.

Code 1:

Main.py

from selenium import webdriver
driver = webdriver.Chrome()

What I get when running on another pc:

Error 1:

Cannot find Chrome Path

   C:\Users\Aperture Science\Desktop\1>123.exe
    Traceback (most recent call last):
      File "site-packages\selenium\webdriver\common\service.py", line 74, in start
      File "subprocess.py", line 709, in __init__
      File "subprocess.py", line 997, in _execute_child
    FileNotFoundError: [WinError 2] The system cannot find the file specified

    During handling of the above exception, another exception occurred:

    Traceback (most recent call last):
      File "main.py", line 42, in <module>
      File "main.py", line 33, in main
      File "site-packages\selenium\webdriver\chrome\webdriver.py", line 68, in __init__
      File "site-packages\selenium\webdriver\common\service.py", line 81, in start
    selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

    [2228] Failed to execute script main

How can I get around this?

What I get from link provided:

Code 2:

from selenium import webdriver
import os, sys, inspect
current_folder = os.path.realpath(os.path.abspath(os.path.split(inspect.getfile(inspect.currentframe() ))[0]))
chromedriver = os.path.join(current_folder,"chromedriver.exe")
driver = webdriver.Chrome(executable_path = chromedriver)
driver.get("http://www.imdb.com/")

REQUIRES Chrome exe in set path, bundled chrome not read. So packaged chrome does not work as desired.


Solution

  • Use --add-binary to bundle the driver in the application:

    pyinstaller -F --add-binary "C:\drivers\chromedriver.exe";"." script.py
    

    and use sys._MEIPASS to get the folder where the driver is extracted:

    import sys, os, time
    from selenium import webdriver
    
    if __name__ == "__main__":
    
      if getattr(sys, 'frozen', False): 
        # executed as a bundled exe, the driver is in the extracted folder
        chromedriver_path = os.path.join(sys._MEIPASS, "chromedriver.exe")
        driver = webdriver.Chrome(chromedriver_path)
      else:
        # executed as a simple script, the driver should be in `PATH`
        driver = webdriver.Chrome()
    
      driver.get("https://stackoverflow.com")
      time.sleep(5)
    
      driver.quit()
