Python 3.4 cx_freeze [WinError 5] using Selenium - Only on other machines

I've recently started devling into cx_freeze and creating .exe files for other people to use.

The script is fairly simple: It uses Selenium to scrape javascript-sensitive content on a website, and gives the user a notification when it finds a matching href + copies the link to the clipboard:

The main code in main.py:

from bs4 import BeautifulSoup
from selenium import webdriver
import time
import pyperclip

def check():
    browser.get(browser.current_url)
    page_html = browser.page_source.encode('utf8')
    soup = BeautifulSoup(page_html, "lxml")
    complete_list = soup.find_all('a', href=True)

    for a in complete_list:
        if LINK_TO_FIND in a['href']:
            pyperclip.copy(a['href'])
            while True:
                beep()

browser = webdriver.Chrome(executable_path=path_to_chromedriver)
browser.get(URL_TO_CHECK)

while True:

    check()
    time.sleep(5)

The cx_freeze code in setup.py:

import sys
from cx_Freeze import setup, Executable

build_exe_options = {"packages": ["os", "lxml", "gzip"], "excludes": ["tkinter"]}

base = 'Console'

setup(  name = "web_scraper",
    version = "0.1",
    description = "desc",
    options = {"build_exe": build_exe_options},
    executables = [Executable("main.py", base=base)])

Until yesterday, this script was running fine on both mine and other machines. But starting yesterday, this error has started to pop up whenever someone else runs the newly built .exe:s. (New ones still works fine for me, old versions still work on other machines):

Traceback (most recent call last):
    File "C:\Python34\lib\site-packages\selenium\webdriver\chrome\service.py", line 68, in start

    File "C:\Python34\lib\subprocess.py", line 1112, in _execute_child
PermissionError: [WinError 5] Access is denied

During handling of the above exception, another exception occured:

Traceback (most recent call last):
    File "C:\Python34\lib\site-packages\cx_Freeze\initscripts\Console.py", line 27, in (module)
    File "main.py", line 48, in (module)

selenium.common.exceptions.WebDriverException: Message: 'exe.win32-3.4' executable may have wrong permissions. Please see https://sites.google.com/a/chromium.org/chromedriver/home

Some things I've tried:

  • Compiling old versions just to check if there was something wrong with the code.
  • Launch the console as admin when doing python setup.py build
  • Disable my antivirus
  • Made sure chromedriver.exe is in the right place (if not, another error is raised).
Solution

  • Alright, so after about 4 hours of troubleshooting I realized that the path_to_chromedriver was missing \chromedriver.exe at the end for the version I was sending over, but was correct for the verison I was using locally. Shoot me.
