Firefox Webtreiber für Selenium in Python

Question

Ich benutze Selen 3.0.1 mit Firefox 48 auf OS X in Python 3. Ich kann Firefox nicht als Webtreiber arbeiten.

from selenium import webdriver 
driver = webdriver.Firefox() 

gibt den folgenden Fehler:

---------------------------------------------------------------------------

Answer 1

Mit Selen 3 oder höher, müssen Sie Gecko-Treiber verwenden Firefox zum Laufen zu bringen:

Java

System.setProperty("webdriver.gecko.driver","path of geckodriver.exe"); 
WebDriver driver = new FirefoxDriver(); 

Python

from selenium import webdriver 
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities 
firefox_capabilities = DesiredCapabilities.FIREFOX 
firefox_capabilities['marionette'] = True 
firefox_capabilities['binary'] = 'C:\Users\test\tools\Firefox' 
driver = webdriver.Firefox(capabilities=firefox_capabilities)

1. Stellen Sie sicher, die richtige tar.gz-Datei herunterladen.
2. Nachdem Sie hier gehen https://github.com/mozilla/geckodriver/releases - suchen Sie nach macos.tar.gz Version von geckodriver.
3. Laden Sie es auf den Desktop und öffnen Sie es.
4. Wählen Sie nun im Finder die Option 'Gehe zu' und dann 'Gehe zu Ordner'. Geben Sie/usr/local/bin ein und fügen Sie den Geckodriver in den Papierkorb ein.
