Dotaz: Selenium webdriver ma problem s geckodriverem

[zdenek2008]

Na nasledujici sestave mam problem se seleniem, ci spise s geckodriverem. Problem se na diskuznich forech objevuje pomerne casto a rady k vyreseni jsou velice ruznorode a pomerne chaoticke. Nemeli byste nekdo s timto nejakou zkusenost nebo nejaky tip co s tim? Kdyztak predem diky za pripadne tipy.

Ma sestava:
debian 10 stable
python 3.7.3
python3-selenium 3.14.1+dfsg1-1
1596572279280   geckodriver     INFO    Listening on 127.0.0.1:4444 (mam za to ze verze je nejnovejsi 0.27 ale nevim jak to overit)
firefox 68.11.0esr (64-bit)


Uvod skriptu:
from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()

Chyba:
  File "/usr/lib/python3/dist-packages/selenium/webdriver/firefox/webdriver.py", line 174, in __init__
    keep_alive=True)
  File "/usr/lib/python3/dist-packages/selenium/webdriver/remote/webdriver.py", line 157, in __init__
    self.start_session(capabilities, browser_profile)
  File "/usr/lib/python3/dist-packages/selenium/webdriver/remote/webdriver.py", line 252, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "/usr/lib/python3/dist-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "/usr/lib/python3/dist-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)

Jeste maly update. Upravil jsem skript pro logovani:

#!/usr/bin/python3
# -*- coding: utf-8 -*-

from selenium import webdriver
from selenium.webdriver.common.keys import Keys


from selenium.webdriver import Firefox
from selenium.webdriver.firefox.options import Options

opts = Options()
opts.log.level = "trace"
driver = Firefox(options=opts)


#driver = webdriver.Firefox()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.close()

Opet jsem dostal stejnou chybovou hlasku; toto je obsah logu:

Tak to mam vyreseno takovouto zmenou ve skriptu:

#!/usr/bin/python3
# -*- coding: utf-8 -*-

from selenium import webdriver
from selenium.webdriver.common.keys import Keys


from selenium.webdriver import Firefox
from selenium.webdriver.firefox.options import Options

from selenium.webdriver.firefox.firefox_binary import FirefoxBinary


#opts = Options()
#opts.log.level = "trace"
#driver = Firefox(options=opts)





binary = FirefoxBinary('/usr/lib/firefox-esr/firefox-esr')
driver = webdriver.Firefox(firefox_binary=binary)
#driver.get('https://google.com')



#driver = webdriver.Firefox()
driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
#driver.close()

Kazdopadne diky za zajem a preji vsem prijemny den.
