WebDriverException: 'geckodriver' executable needs to be in PATH even though it is

问题

Trying to get firefox to run using selenium in spyder. My current code is

from selenium import webdriver
import os
os.environ[\"PATH\"] += \":/usr/local/bin/geckodriver\"
browser = webdriver.Firefox()

and I still get this error:

runfile(\'/Users/mherl/Dropbox/AnacondaProjects/MWS/MWSSpyder/test.py\', 
wdir=\'/Users/mherl/Dropbox/AnacondaProjects/MWS/MWSSpyder\')

WebDriverException: \'geckodriver\' executable needs to be in PATH. 

Even though gekodriver is in that folder.

I have also tried exporting the path to ~./bash_profile which looks like this right now.

export PATH

# added by Anaconda3 5.1.0 installer
export PATH=\"/Applications/anaconda3/bin:$PATH\"

#added by mherl to show path to gekodriver
export PATH=$PATH:/usr/local/bin/gekodriver

I also have the current paths set in spyder:

/usr/local/bin
/Users/mherl/Dropbox/AnacondaProjects/MWS/MWSSpyder

of which gekodriver is in

/usr/local/bin

I have looked everywhere and most people say it should run automatically if it\'s in /usr/local/bin but it still can\'t seem to find it even when I explicitly state the path.

This is a mac running High Sierra if that\'s important.

回答1:

This error message...

WebDriverException: 'geckodriver' executable needs to be in PATH. 

...implies that the GeckoDriver wasn't found in the expected default location.

Solution

As you are using MAC based System you need to pass the Key executable_path along with the Value referring to the absolute path of the GeckoDriver as follows :

from selenium import webdriver

browser = webdriver.Firefox(executable_path='/usr/local/bin/geckodriver')

Additional Consideration

Ensure the following :

• GeckoDriver is present in the specified location.
• GeckoDriver is having executable permission for non-root users.
• Execute your @Test as a non-root user.
