Mac M1环境下Selenium网页爬取chromedriver路径错误求助

问题描述 #

在Mac M1设备上使用Selenium爬取网页时，遇到chromedriver路径相关错误，代码及错误信息如下：

代码 #

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

chromeOptions = Options()
chromeOptions.headless = False

s = Service("usr/local/bin/chromedriver")
driver = webdriver.Chrome(service= s, options = chromeOptions )

错误信息 #

     97                 except WebDriverException as new_err:

During handling of the above exception, another exception occurred:

WebDriverException                        Traceback (most recent call last)

    211             if err.errno == errno.ENOENT:

    213                     f"'{os.path.basename(self.path)}' executable needs to be in PATH. {self.start_error_message}"
    214                 )

WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://chromedriver.chromium.org/home

解决方法 #

• 修正路径拼写：代码中路径缺少开头斜杠，应改为/usr/local/bin/chromedriver，否则系统无法识别为绝对路径。
• 匹配Chrome与chromedriver版本：
  1. 查看Chrome版本（设置→关于Chrome）。
  2. 下载对应版本的arm64架构chromedriver，解压后放到/usr/local/bin，或直接在代码中指定解压后的完整路径。
• 用Homebrew安装：终端执行brew install chromedriver，安装完成后代码中无需手动指定路径，直接写Service()即可，Homebrew会自动处理架构和PATH配置。
• 禁用Selenium Manager：若环境存在架构混淆，在代码开头添加：

  import os
  os.environ['SE_DONT_USE_SM'] = '1'
  

  确保手动指定的chromedriver是适配M1的arm64版本。
• 检查Python架构：终端执行python3 -c "import platform; print(platform.machine())"，确认输出为arm64。若为x86_64，重新安装适配M1的Python版本。
