错误消息:“chromedriver"可执行文件需要是 PATH

2022-01-15 00:00:00 python selenium selenium-chromedriver selenium-webdriver google-chrome

问题描述

我刚开始使用 Selenium 并且能够加载 google，但现在当我运行以下代码时会产生错误:

I just started on Selenium and was able to load up google but now when I run the following code it produces the error:

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

为什么说C:Users/Colin/Python/chromedriver"不是路径?

Why is it saying "C:Users/Colin/Python/chromedriver" is not a path?

from selenium import webdriver

browser = webdriver.Chrome("C:Users/Colin/Python/chromedriver")
browser.get('http://www.google.com')

browser.quit()

解决方案

使用 Selenium v​​3.x、ChromeDriver 和 Chrome 浏览器您可能需要通过以下任一选项将参数 executable_path 与 ChromeDriver 二进制文件的 绝对路径 一起传递:

While working with Selenium v3.x, ChromeDriver and Chrome Browser you may need to pass the argument executable_path along with the absolute path of the ChromeDriver binary through either of the following options:

  • 双反斜杠，即 (\)
  • 单反斜杠，即 () 以及原始 (r) 开关.
  • 二进制扩展名，即(.exe)
  • Double back slashes i.e. (\)
  • Single back slash i.e () along with the raw (r) switch.
  • Binary extension i.e. (.exe)

所以你必须换行:

browser = webdriver.Chrome("C:Users/Colin/Python/chromedriver")

与:

browser = webdriver.Chrome(executable_path=r'C:UsersColinPythonchromedriver.exe')
