Selenium Firefox driver raise exception OSError: [Errno 8] Exec format error

问题

def setUp(self):
   display = Xvfb()
   display.start()
   fp = webdriver.FirefoxProfile()
   fp.set_preference("browser.download.folderList",2)
   fp.set_preference("browser.download.manager.showWhenStarting",False)
   fp.set_preference("browser.helperApps.neverAsk.saveToDisk","text/csv")
       self.browser= webdriver.Firefox(firefox_profile=fp)

On webdriver.firefox it raises an exception even I tried with geckodriver path

self.browser=webdriver.Firefox(executable_path='/usr/bin/geckodriver',firefox_profile=fp)

But still it raises an exception

 Traceback (most recent call last):
  File "fbCampaign.py", line 23, in setUp
    self.browser= webdriver.Firefox(executable_path='/usr/bin/geckodriver',firefox_profile=fp)

回答1:

This error message...

OSError: [Errno 8] Exec format error

...means the geckodriver binary which you are trying to use was compiled for a different platform.

Solution

Download the GeckoDriver binary specific to your platform (Windows, Mac, Linux) from GeckoDriver Release Repository.

You must choose the correct GeckoDriver binary to match the underlying OS it will be run on:

geckodriver-v0.22.0-linux32.tar.gz: For Linux OS.
geckodriver-v0.22.0-macos.tar.gz: For MAC OSX.
geckodriver-v0.22.0-win32.zip: For Windows 32-bit OS.
geckodriver-v0.22.0-win64.zip: For Windows 64-bit OS.

Note: Once you download you need to unzip / untar the GeckoDriver binary.
