Selenium.common.exceptions.WebDriverException：消息：未知錯誤：沒有 chrome 二進制文件

Question

我正在嘗試運行幾個月前制作的 python 腳本，該腳本使用 selenium 來抓取 web 頁面。 這是我的代碼：

import pandas as pd
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

driver = webdriver.Chrome(executable_path="/users/aliallam/Documents/chromedriver")

這是我得到的完整錯誤：

Traceback (most recent call last):
  File "/Users/aliallam/Desktop/MISOS_Python_Scraper/main.py", line 16, in <module>
    driver = webdriver.Chrome(executable_path="/users/aliallam/Documents/chromedriver")
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/chrome/webdriver.py", line 76, in __init__
    RemoteWebDriver.__init__(
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/remote/webdriver.py", line 157, in __init__
    self.start_session(capabilities, browser_profile)
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/remote/webdriver.py", line 252, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: unknown error: cannot find Chrome binary

我在這個問題下嘗試了解決方案，但仍然沒有運氣： Selenium 在 Mac 上給出“selenium.common.exceptions.WebDriverException：消息：未知錯誤：找不到 Chrome 二進制文件”

這是我將代碼更改為：

options = webdriver.ChromeOptions()
options.binary_location = " /Applications/Google\ Chrome\ 2.app"
chrome_driver_binary = "/users/aliallam/Documents/chromedriver"
driver = webdriver.Chrome(chrome_driver_binary,chrome_options=options)

這真是令人沮喪，一些幫助將不勝感激！ 提前致謝！

Answer 1

編輯：除了以下錯誤，我認為您還需要將二進制位置更改為/Applications/Google Chrome 2.app/Contents/MacOS/Google Chrome

根據您發布的內容，我認為該錯誤是因為此行中第一個引號后有一個額外的空格：

options.binary_location = " /Applications/Google\ Chrome\ 2.app"

嘗試將其更改為：

options.binary_location = "/Applications/Google Chrome 2.app/Contents/MacOS/Google Chrome"

並重新運行代碼。

基於您提供的完整代碼：

from selenium import webdriver

options = webdriver.ChromeOptions()
options.binary_location = "/Applications/Google Chrome 2.app/Contents/MacOS/Google Chrome"
chrome_driver_binary = "/users/aliallam/Documents/chromedriver"
driver = webdriver.Chrome(chrome_driver_binary,chrome_options=options)

如果這不起作用，您也可以嘗試

from selenium import webdriver

options = webdriver.ChromeOptions()
options.binary_location = "/Applications/Google Chrome 2.app/Contents/MacOS/Google Chrome"
executable_path = "/users/aliallam/Documents/chromedriver"
driver = webdriver.Chrome(executable_path=executable_path, chrome_options=options)

對於 MacOS 上的我來說，當我將下載的“Google Chrome”應用程序從“下載”文件夾移動到“應用程序”文件夾時，錯誤得到了解決
