[🐛 Bug]: webdriver - Process unexpectedly closed with status 127 (Geckodriver) #11414

self-dmz · 2022-12-12T13:30:04Z

What happened?

Hi!

Just trying to start working with Geckodriver get the following exception: "selenium.common.exceptions.WebDriverException: Message: Process unexpectedly closed with status 127".

Using Chrome driver the code below works fine.

webdriver-manager==3.8.5
selenium==4.7.2

Thanks in advance

How can we reproduce the issue?

# Try to start this script

from selenium import webdriver
from selenium.webdriver.firefox.options import Options
from selenium.webdriver.firefox.service import Service as FirefoxService
from webdriver_manager.firefox import GeckoDriverManager

opts = Options()
opts.log.level = "trace"
opts.add_argument('--headless')

# ------ Process unexpectedly closed with status 127
driver = webdriver.Firefox(service=FirefoxService(GeckoDriverManager().install()))

# ------ Process unexpectedly closed with status 127
#driver = webdriver.Firefox(options=opts, executable_path=GeckoDriverManager().install())
#driver = webdriver.Firefox(executable_path="/media/dmz/HDD/geckodriver/geckodriver")

# ------ Process unexpectedly closed with status 127
#service = FirefoxService(executable_path="/media/dmz/HDD/geckodriver/geckodriver")
#driver = webdriver.Firefox(options=opts, service=service)

driver.get('https://google.com')

print(driver.title)

What happens if you avoid webdriver-manager? Selenium has an embedded manager for drivers (called Selenium Manager) since 4.6.0.

self-dmz · 2022-12-12T14:05:22Z

`! --- The same exception is got - "Process unexpectedly closed with # status 127"

import time
from selenium import webdriver

driver = webdriver.Firefox() # Message: Process unexpectedly closed with status 127

driver = webdriver.Chrome() # -- works OK !

driver.maximize_window()
driver.get('https://google.com/')
print(driver.title)

time.sleep(3)
driver.quit()`

@self-dmz can you try the same example with a virtual env that is not residing in /media/ ?

self-dmz · 2022-12-12T18:36:27Z

I tired with new project created at /home... It fails with the same exception. webdriver.Chrome() works properly. The same script is used.

Traceback (most recent call last):

I got the same error, and a geckodriver.log in the working directory contained lines like

1672176966006	geckodriver	INFO	Listening on 127.0.0.1:38849
/snap/firefox/current/firefox.launcher: 46: exec: /snap/pycharm-professional/314/usr/lib/firefox/firefox: not found

/snap/firefox/current/firefox.launcher: 46: exec: /snap/pycharm-professional/314/usr/lib/firefox/firefox: not found

You can see I am using a snap install of PyCharm which seems to be messing up the path to the firefox executable?
This is on Ubuntu 22.04, Python 3.10.6, with selenium==4.7.2 and webdriver-manager==3.8.5 installed in a venv.

(so I ran my code again in a terminal outside PyCharm and got a different error, but I guess that's a different issue):

plus a nice popup error message window Your Firefox profile cannot be loaded. It may be missing or inaccessible. And the exception message this time is Process unexpectedly closed with status 1

Snap is a pain for selenium. It has its own driver and none of the driver managers support it. You need to explicitly pass on the location to the driver in the service constructor.

@self-dmz are you also using snap?

benxyzzy · 2022-12-28T15:24:44Z

Following @titusfortner 's advice and this, the following works for me, within PyCharm and not needing to do anything special regarding Firefox profile locations:

    install_dir = "/snap/firefox/current/usr/lib/firefox"
    driver_loc = os.path.join(install_dir, "geckodriver")
    binary_loc = os.path.join(install_dir, "firefox")

    service = FirefoxService(driver_loc)
    opts = webdriver.FirefoxOptions()
    opts.binary_location = binary_loc
    driver = webdriver.Firefox(service=service, options=opts)

Note that the opts.binary_location is required, not just the driver location.

/snap/firefox/current is a symlink to the current version directory within /snap/firefox, so I'm hoping that is a better way to dynamically keep pointed at the right binary + driver, without the subprocess("find ...") hack in the SO answer

yes, firefox installed via snap. and the scheme described by @benxyzzy also works on my PC.

many thanks, @benxyzzy! the code you provided works in my case.

Hi, guys! I have such problem: NameError: name 'FirefoxService' is not defined

hotenov · 2023-03-06T10:09:48Z

@AntiPetrun Hi! Check your imports, because in issue description more common Service was imported as FirefoxService (with other module name)

from selenium.webdriver.firefox.service import Service as FirefoxService

manel00 · 2023-07-11T07:58:24Z

Hello, still having the same issue... anyone knows how to fix it? I am using ubuntu 22

titusfortner · 2023-09-14T16:45:30Z

As of Selenium 4.11, you don't need to import as for the service classes (https://www.selenium.dev/documentation/webdriver/drivers/service/#default-service-instance)

try:

    install_dir = "/snap/firefox/current/usr/lib/firefox"
    driver_loc = os.path.join(install_dir, "geckodriver")
    binary_loc = os.path.join(install_dir, "firefox")

    service = webdriver.FirefoxService(driver_loc)
    opts = webdriver.FirefoxOptions()
    opts.binary_location = binary_loc
    driver = webdriver.Firefox(service=service, options=opts)
