问题
I'm on OS Sierra and i'm running Python 3.5.2. I have selenium installed and i'm following a book called "Automate the Boring Tasks With Python"
My code is
from selenium import webdriver
>>> browser = webdriver.Firefox()
I keep receiving the error
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/selenium/webdriver/common/service.py", line 64, in start

During handling of the above exception, another exception occurred:

selenium.common.exceptions.WebDriverException: Message: 'geckodriver' executable needs to be in PATH.
I have searched far and wide for solutions to my issue. Many people have the same issue.. but none of the solutions are working. I have geckodriver copied everywhere in my Python folders. I've tried using terminal and I have tried specifying the path within the code and it still gives me errors. I hope somebody can help me. I'm sorry if this is in the wrong format, I don't know what i'm doing.
回答1:
I faced this same problem and here's how I fixed it:
- Download the
geckodriverfrom here - Extract and unzip and move the
geckodriverfile to/usr/local/bin/directory - Run python program with selenium
Firefoxwebdriver.
回答2:
This answer can be easily solved by a google search for "add program to path"
export PATH=$PATH:/path/to/geckodriver
回答3:
"I have geckodriver copied everywhere in my Python folders." Ensure the geckodriver executable is found in one of the paths when you run:
import sys
print sys.path
And the problem should be resolved.
