Selenium using Python - Geckodriver executable nee

Question

I'm new to programming and started with Python about 2 months ago and am going over Sweigart's Automate the Boring Stuff with Python text. I'm using IDLE and already installed the selenium module and the Firefox browser. Whenever I tried to run the webdriver function, I get this:

from selenium import webdriver
browser = webdriver.Firefox()

Exception :-

Exception ignored in: <bound method Service.__del__ of <selenium.webdriver.firefox.service.Service object at 0x00000249C0DA1080>>
Traceback (most recent call last):
  File "C:\Python\Python35\lib\site-packages\selenium\webdriver\common\service.py", line 163, in __del__

    startupinfo)

During handling of the above exception, another exception occurred:

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH. 

I think I need to set the path for geckodriver but not sure how, so can anyone tell me how would I do this?

Answer 1

If you are using Anaconda, all you have to do is activate your virtual environment and then install geckodriver using the following command:

    conda install -c conda-forge geckodriver

Answer 2

I am using Windows 10 and Anaconda2. I tried setting system path variable but didn't worked out. Then I simply added geckodriver.exe file to Anaconda2/Scripts folder and everything works great now. For me the path was:-

C:\Users\Bhavya\Anaconda2\Scripts

Answer 3

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.

First of all you will need to download latest executable geckodriver from here to run latest firefox using selenium

Actually The Selenium client bindings tries to locate the geckodriver executable from the system PATH. You will need to add the directory containing the executable to the system path.

• On Unix systems you can do the following to append it to your system’s search path, if you’re using a bash-compatible shell:

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

• On Windows you will need to update the Path system variable to add the full directory path to the executable geckodriver manually or command line(don't forget to restart your system after adding executable geckodriver into system PATH to take effect). The principle is the same as on Unix.

Now you can run your code same as you're doing as below :-

from selenium import webdriver

browser = webdriver.Firefox()

selenium.common.exceptions.WebDriverException: Message: Expected browser binary location, but unable to find binary in default location, no 'moz:firefoxOptions.binary' capability provided, and no binary flag set on the command line

Exception clearly states you have installed firefox some other location while Selenium is trying to find firefox and launch from default location but it couldn't find. You need to provide explicitly firefox installed binary location to launch firefox as below :-

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary = FirefoxBinary('path/to/installed firefox binary')
browser = webdriver.Firefox(firefox_binary=binary)

Answer 4

I'm using Windows 10 and this worked for me:

1. Download geckodriver from here . Download the right version for the computer you are using
2. Unzip the file you just downloaded and cut/copy the ".exe" file it contains
3. Navigate to C:{your python root folder}. Mine was C:\Python27. Paste the geckodriver.exe file in this folder.
4. Restart your development environment.
5. Try running the code again, it should work now.

Answer 5

Mac 10.12.1 python 2.7.10 this work for me :)

def download(url):
firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
browser = webdriver.Firefox(capabilities=firefox_capabilities,
                            executable_path=r'/Users/Do01/Documents/crawler-env/geckodriver')
browser.get(url)
return browser.page_source

Answer 6

this steps SOLVED for me on ubuntu firefox 50.

1. Download geckodriver

2. Copy geckodriver in /usr/local/bin

You do NOT need to add

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
firefox_capabilities['binary'] = '/usr/bin/firefox'
browser = webdriver.Firefox(capabilities=firefox_capabilities)
