python - 使用 chromedriver 和 selenium 时出现错误

问题描述

我正在尝试编写代码以将消息发送到 whatsapp 中的人员列表到具有 selenium 和 chromedriver 的人员列表，但我收到此错误：

C:\Users\Crist\Desktop\Whattsapp mama>prueba.py
Traceback (most recent call last):
  File "C:\Users\Crist\Desktop\Whattsapp mama\prueba.py", line 10, in <module>
    driver = webdriver.Chrome(r"C:\Users\Crist\Downloads\chromedriver\chromedriver.exe")

    RemoteWebDriver.__init__(

  File "C:\Users\Crist\AppData\Local\Programs\Python\Python39\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 252, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)

    self.error_handler.check_response(response)

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Chrome binary
(Driver info: chromedriver=2.25.426923 (0390b88869384d6eb0d5d09729679f934aab9eed),platform=Windows NT 10.0.19042 x86_64)

这是代码：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support.ui import Select
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
import time
contact = ["cristobal de toro", "cristobal", "gonzalo molina"]
text = "Hey, this message was sent using Selenium"
driver = webdriver.Chrome(r"C:\Users\Crist\Downloads\chromedriver\chromedriver.exe")
driver.get("https://web.whatsapp.com")

标签： pythonselenium

解决方案

试试看，它可能有助于安装和设置正确的 chromedriver 路径：

安装 webdriver-manager 包：

pip install webdriver-manager

并将其添加到文件中：

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(ChromeDriverManager().install())

而不是那一行：

driver = webdriver.Chrome(r"C:\Users\Crist\Downloads\chromedriver\chromedriver.exe")
