Use selenium with chromedriver on Mac

Question

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

1. I download the chromedriver from ChromeDriver - WebDriver for Chrome
2. 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

3. 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:

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

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

Answer 1

For me worked like this without complicating things

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