为什么我的 selenium 不能在 python 脚本中工作？

Question

I'm having some issues with selenium in my python script.

import time
from selenium import webdriver
browser = webdriver.Chrome(path/to/chromedriver)

After executing the script the terminal is just outputting:

SyntaxError: invalid syntax

the problem is in third line

browser = webdriver.Chrome(path/to/chromedriver)

and I don't really know what to do. I'm pretty sure that the chrome driver path is correct tho.

Answer 1

Should be, assuming you are on windows

browser = webdriver.Chrome(executable_path=r"C:\path\to\chromedriver.exe")

Or

browser = webdriver.Chrome(executable_path="C:\\path\\to\\chromedriver.exe")

Webdriver download

https://sites.google.com/a/chromium.org/chromedriver/downloads

You can also download and install the chromedriver binary

Just import chromedriver_binary . This will add the executable to your PATH so it will be found.

You can also get the absolute filename of the binary with chromedriver_binary.chromedriver_filename.

from selenium import webdriver
import chromedriver_binary  # Adds chromedriver binary to path

driver = webdriver.Chrome()

Answer 2

For Windows:

You have to put the path as a string in quotes "<path to chromdriver>" and would have to use r (for raw) before the string if it only includes single \ eg r"C:\Users\user\..." else you don't need it if you path is like "C:\\Users\\user..." .

Do:

import time
from selenium import webdriver
browser = webdriver.Chrome(r"<path to chromedriver>")

where "path to chromedriver" is the path to the chromedriver eg "C:\Users\<user>\Downloads\chromedriver_win32\chromedriver.exe" .

Answer 3

I would suggest using the webdriver_manager , as it will take care of downloading the latest stable driver based on the browser version and also takes care of the execution paths.

Use the below 3 simple lines to start the chrome driver.

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager``

driver = webdriver.Chrome(ChromeDriverManager().install()

Make sure you have selenium and webdriver_manager libraries added to the project.
