python - 无头 Python Selenium 显示错误“chromedriver”可执行文件需要在 PATH 中

问题描述

我正在运行一个 selenium 脚本，我想在不使用 chrome 选项打开浏览器的情况下运行我的代码。我尝试将驱动程序设置为 PATH，然后将其更改为 options=op 但它显示了相同的错误（我的代码中的文件路径是准确的）。我按照这篇文章的第二个答案并尝试在 cmd 中运行 chromedriver.exe（不确定这是否相关，但我在另一篇文章中看到了这个并认为它可能有用）。下面的片段是输出：

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.

这是我的代码：

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)

这是我收到的错误：

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,

    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
FileNotFoundError: [WinError 2] The system cannot find the file specified

During handling of the above exception, another exception occurred:

    driver = webdriver.Chrome(options=op)

    self.service.start()

    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

我定义驱动程序的方式有问题吗？

解决方案

你的字符串是错误的。如果您想\在字符串中使用，请执行原始字符串PATH = r"C:\Program Files (x86)\chromedriver.exe"
