Headless Python Selenium 显示错误 'chromedriver' 可执行文件需要在 PATH 中

Question

I am running a selenium script and I would like to run my code without opening the browser using chrome options. I tried setting driver to PATH and then changing it to options=op but it showed the same error (The file path in my code is accurate). I followed the second answer on this post and tried running chromedriver.exe in cmd (Not sure if this is relevant in but i saw this in another post and thought it could be of use). The snippet below was the output:

c:\Program Files (x86)>chromedriver
Starting ChromeDriver 86.0.4240.22 (398b0743353ff36fb1b82468f63a3a93b4e2e89e-refs/branch-heads/4240@{#378}) on port 9515
Only local connections are allowed.
Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver safe.
ChromeDriver was started successfully.

Here is my code:

from selenium import webdriver

PATH = "C:\Program Files (x86)\chromedriver.exe"
op = webdriver.ChromeOptions()
op.add_argument('headless')
# driver = webdriver.Chrome(PATH)
driver = webdriver.Chrome(options=op)

And here is the error I am receiving:

Traceback (most recent call last):
  File "C:\Users\soodr\PythonFiles\lib\site-packages\selenium\webdriver\common\service.py", line 72, in start
    self.process = subprocess.Popen(cmd, env=self.env,

During handling of the above exception, another exception occurred:

    raise WebDriverException(
selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

Is there something wrong about the way I am defining driver?

Answer 1

your string is wrong. if you wanna use \ in a string, do a raw string that is PATH = r"C:\Program Files (x86)\chromedriver.exe"
