Use selenium with chromedriver on Mac

Question

I want to use selenium with chromedriver on Mac,but I have some troubles on it.

I download the chromedriver from ChromeDriver - WebDriver for Chrome
But I don't want to put it to PATH.So I do this.

import os

from selenium import webdriver

PROJECT_ROOT = os.path.abspath(os.path.dirname(__file__))
DRIVER_BIN = os.path.join(PROJECT_ROOT, "bin/chromedriver_for_mac")
print DRIVER_BIN
browser = webdriver.Chrome(DRIVER_BIN)
browser.get('http://www.baidu.com/')

But I can't get the result I want.

Traceback (most recent call last):
  File "/Users/wyx/project/python-scraping/se/test.py", line 15, in <module>
    browser = webdriver.Chrome(DRIVER_BIN)
  File "/Users/wyx/project/python-scraping/.env/lib/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 62, in __init__
    self.service.start()
  File "/Users/wyx/project/python-scraping/.env/lib/python2.7/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: 'chromedriver_for_mac' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

Exception AttributeError: "'Service' object has no attribute 'process'" in <bound method Service.__del__ of <selenium.webdriver.chrome.service.Service object at 0x107f96150>> ignored

Then I run brew cask install chromedriver.And I only run this without the driver path.
```
browser = webdriver.Chrome()
browser.get('http://www.baidu.com/')
```

But it can't work either.

Traceback (most recent call last):
  File "/Users/wyx/project/python-scraping/se/test.py", line 16, in <module>
    browser = webdriver.Chrome()
  File "/Users/wyx/project/python-scraping/.env/lib/python2.7/site-packages/selenium/webdriver/chrome/webdriver.py", line 62, in __init__
    self.service.start()
  File "/Users/wyx/project/python-scraping/.env/lib/python2.7/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: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

Exception AttributeError: "'Service' object has no attribute 'process'" in <bound method Service.__del__ of <selenium.webdriver.chrome.service.Service object at 0x105c08150>> ignored

Process finished with exit code 1

Finally I try to put it to /usr/bin

➜  Downloads sudo cp chromedriver /usr/bin
Password:
cp: /usr/bin/chromedriver: Operation not permitted

and I try to use export PATH=$PATH:/Users/wyx/project/python-scraping/se/bin/chromedriver_for_mac in .zshrc . But

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

So how to solve it，I want to use it with the driver path not in the PATH so I can deploy my project easily.

Solution:

brew cask install chromedriver
which chromedriver get the driver path
And then use it like this webdriver.Chrome("/usr/local/bin/chromedriver")

But I don't know why so complex to use selenium.

as of 2023, the brew install chromedriver --cask location is /opt/homebrew/bin/chromedriver — james-see

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

To launch chrome browser using ChromeDriver you need to pass executable chromedriver location with executable itself into executable_path.

You should try as below :-

import os
from selenium import webdriver

PROJECT_ROOT = os.path.abspath(os.path.dirname(__file__))
DRIVER_BIN = os.path.join(PROJECT_ROOT, "bin/chromedriver_for_mac")

browser = webdriver.Chrome(executable_path = DRIVER_BIN)
browser.get('http://www.baidu.com/')

Or set PATH variable using command with executable as :-

export PATH=$PATH:/Users/wyx/project/python-scraping/se/bin/chromedriver_for_mac

Then try to Initialize ChromeDriver as :-

from selenium import webdriver

browser = webdriver.Chrome()
browser.get('http://www.baidu.com/')

This two methods I have tried.It show me the same error what I have said above @Saurabh Gaur

Saurabh Gaur Over a year ago

I know you've tried but you haven't pass executable chromedriver itself with location that's why you're in trouble

Saurabh Gaur Over a year ago

To lunch ChromeDriver you need to pass executable directory with executable file also not only directory, make attention

Saurabh Gaur Over a year ago

@wyx And you have to pass executable chromedriver path into executable_path variable, see provided answer carefully..

Saurabh Gaur Over a year ago

Actually you are modifying the name of chromedriver to chromedriver_for_mac that's why @wyx it couldn't find when you installed through brew, and this case you just Initialize as webdriver.Chrome() and it itself would find the chromedriver executable from bin folder but it should be named as chromedriver..:)

For sake of simplicity:

Download the chrome webdriver from this link. Copy the 'chromedriver' in the folder of python script.

from selenium import webdriver
import os

url = 'http://www.webscrapingfordatascience.com/complexjavascript/'

PROJECT_ROOT = os.path.abspath(os.path.dirname(__file__))
DRIVER_BIN = os.path.join(PROJECT_ROOT, "chromedriver")

driver = webdriver.Chrome(executable_path = DRIVER_BIN)

driver.get(url)

input('Press ENTER to close the automated browser')

driver.quit()

For me worked like this without complicating things

Download chromedriver from official link (notice version of Chrome browser)
Unpack *.zip file and file chromedriver copy to location usr/local/bin/
Remove any path you put in file and just go with driver = webdriver.Chrome()
If probem still exist try to reopen PyCharm since sometimes need to be reopened in case to work

One step to mention at the end: if not done, allow chromedriver in the security & privacy menu on your mac

For me, installing chromedriver through homebrew worked like a charm on MacOS 11.

brew install chromedriver && brew update

this worked for me too. Also, remember apple might block this app from starting remember to unblock it from security & privacy.

james-see Over a year ago

as of 2023, the command is brew install chromedriver --cask and location is /opt/homebrew/bin/chromedriver
