Selenium using Python - Geckodriver executable needs to be in PATH -


i'm new programming , started python 2 months ago , going on sweigart's automate boring stuff python text. i'm using idle , installed selenium module , firefox browser. whenever tried run webdriver function, this:

from selenium import webdriver browser = webdriver.firefox()

exception :-

exception ignored in: <bound method service.__del__ of <selenium.webdriver.firefox.service.service object @ 0x00000249c0da1080>> traceback (most recent call last):   file "c:\python\python35\lib\site-packages\selenium\webdriver\common\service.py", line 163, in __del__     self.stop()   file "c:\python\python35\lib\site-packages\selenium\webdriver\common\service.py", line 135, in stop     if self.process none: attributeerror: 'service' object has no attribute 'process' exception ignored in: <bound method service.__del__ of <selenium.webdriver.firefox.service.service object @ 0x00000249c0e08128>> traceback (most recent call last):   file "c:\python\python35\lib\site-packages\selenium\webdriver\common\service.py", line 163, in __del__     self.stop()   file "c:\python\python35\lib\site-packages\selenium\webdriver\common\service.py", line 135, in stop     if self.process none: attributeerror: 'service' object has no attribute 'process' traceback (most recent call last):   file "c:\python\python35\lib\site-packages\selenium\webdriver\common\service.py", line 64, in start     stdout=self.log_file, stderr=self.log_file)   file "c:\python\python35\lib\subprocess.py", line 947, in __init__     restore_signals, start_new_session)   file "c:\python\python35\lib\subprocess.py", line 1224, in _execute_child     startupinfo) filenotfounderror: [winerror 2] system cannot find file specified  during handling of above exception, exception occurred:  traceback (most recent call last):   file "<pyshell#11>", line 1, in <module>     browser = webdriver.firefox()   file "c:\python\python35\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 135, in __init__     self.service.start()   file "c:\python\python35\lib\site-packages\selenium\webdriver\common\service.py", line 71, in start     os.path.basename(self.path), self.start_error_message) selenium.common.exceptions.webdriverexception: message: 'geckodriver' executable needs in path.

i think need set path geckodriver not sure how, can tell me how this?

selenium.common.exceptions.webdriverexception: message: 'geckodriver' executable needs in path.

first of need download latest executable geckodriver here run latest firefox using selenium

actually selenium client bindings tries locate geckodriver executable system path. need add directory containing executable system path.

  • on unix systems can following append system’s search path, if you’re using bash-compatible shell:

    export path=$path:/path/to/directory/of/executable/downloaded/in/previous/step

  • on windows need update path system variable add full directory path executable geckodriver manually or command line(don't forget restart system after adding executable geckodriver system path take effect). principle same on unix.

now can run code same you're doing below :-

from selenium import webdriver  browser = webdriver.firefox()

selenium.common.exceptions.webdriverexception: message: expected browser binary location, unable find binary in default location, no 'moz:firefoxoptions.binary' capability provided, , no binary flag set on command line

exception states have installed firefox other location while selenium trying find firefox , launch default location couldn't find. need provide explicitly firefox installed binary location launch firefox below :-

from selenium import webdriver selenium.webdriver.firefox.firefox_binary import firefoxbinary  binary = firefoxbinary('path/to/installed firefox binary') browser = webdriver.firefox(firefox_binary=binary)
