Error Message: "'Chromedriver' Executable Needs to Be Available in the Path"

Error message: 'chromedriver' executable needs to be available in the path

You can test if it actually is in the PATH, if you open a cmd and type in chromedriver (assuming your chromedriver executable is still named like this) and hit Enter. If Starting ChromeDriver 2.15.322448 is appearing, the PATH is set appropriately and there is something else going wrong.

Alternatively you can use a direct path to the chromedriver like this:

 driver = webdriver.Chrome('/path/to/chromedriver') 

So in your specific case:

 driver = webdriver.Chrome("C:/Users/michael/Downloads/chromedriver_win32/chromedriver.exe")

selenium - chromedriver executable needs to be in PATH

You can download ChromeDriver here:
https://sites.google.com/chromium.org/driver/

Then you have multiple options:

• add it to your system path

• put it in the same directory as your python script

• specify the location directly via executable_path

   driver = webdriver.Chrome(executable_path='C:/path/to/chromedriver.exe')
  

WebDriverException: Message: 'chromedriver' executable needs to be in PATH while setting UserAgent through Selenium Chromedriver python

This error message...

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

...implies that the ChromeDriver was not found within the locations specified within PATH variable within Environment Variables.

Solution

You need to pass the Key executable_path along with the Value referring to the absolute path of the ChromeDriver along with the ChromeOptions object as an argument while initializing the WebDriver and WebBrowser as follows :

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('user-agent = Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36')
driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Users\Desktop\chromedriver_win32\chromedriver.exe')
driver.get('https://www.google.co.in')

selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH error with Headless Chrome

If we analyze the logs it seems the main issue is with in start os.path.basename(self.path) and subsequent error message:

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

So it's clear from the error that the Python client was unable to locate the chromedriver executable binary.

You need to take care of a couple of things as follows:

1. chrome_options.binary_location : The parameter points to the chrome.exe not the chromedriver.exe

2. os.path.abspath("chromedriver") will pick up the file path of chromedriver but won't append chromedriver.exe at the end.

3. Here is the sample code on my windows-8 system to start google-chrome-headless:

   from selenium import webdriver  
   from selenium.webdriver.chrome.options import Options 
   
   chrome_options = Options()  
   chrome_options.add_argument("--headless")  
   driver = webdriver.Chrome(chrome_options=chrome_options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')  
   driver.get("http://www.duo.com") 
   print("Chrome Browser Initialized in Headless Mode")
   driver.quit()
   print("Driver Exited")
   

Error chromedriver executable needs to be in PATH

In the self.driver = webdriver.Chrome(), pass the path to the executable as an argument in the parentheses.

For example:

self.driver = webdriver.Chrome('C:/user/Downloads/chromedriver.exe')
