Unable to run chromedriver using selenium in Python in aws cloud9

Question

After I install selenium, chrome, and chromedriver to aws cloud9, I tried to execute chromedriver. But PATH error occurred.

I checked chromedriver path is correct. And I don't know why this error happened.

aws:~/environment/seleniumTest $ ll /home/ec2-user/environment/seleniumTest/chromedriver
-rwxr-xr-x 1 ec2-user ec2-user 8496784 Sep 13  2018 /home/ec2-user/environment/seleniumTest/chromedriver

Are there any solutions to solve this problem?

My steps is as below,

1.install selenium pip install selenium -t ./

2.install chrome curl https://intoli.com/install-google-chrome.sh | bash

3.download chromedriver curl -SL https://chromedriver.storage.googleapis.com/2.42/chromedriver_linux64.zip > chromedriver.zip unzip chromedriver.zip

4.Execute Python code as below

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

def lambda_handler(event, context):
    options = Options()
    options.add_argument('--headless')

    driver = webdriver.Chrome('/home/ec2-use/environment/seleniumTest/chromedriver', chrome_options=options)

    return(0)

I got "'chromedriver' executable needs to be in PATH" error.

Answer 1

I'm not sure you're specifying the executable_path for Chromedriver properly, I think the below should work:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

def lambda_handler(event, context):
    options = Options()
    options.add_argument('--headless')

    driver = webdriver.Chrome(executable_path='/home/ec2-user/environment/seleniumTest/chromedriver', chrome_options=options)

    return(0)
