Chrome 驱动程序 - Selenium

Question

我是 programmin 的新学生，我第一次尝试使用 Chromedriver 和 Selenium。我绝对无法访问下载的文件，不知道为什么。 这是我的输入：

from selenium import webdriver
driver = webdriver.Chrome(executable_path = "/Users/silvia/Desktop/executables/chromedriver")

如下所示，我得到的结果如下。说我的桌面上没有这样的文件，但是有！我尝试了反斜杠，双反斜杠和一切。也许我应该从头开始尝试整个过程！知道为什么不工作吗？提前谢谢！

这是错误信息：

Answer 1

我不知道你是否已经解决了，但这也发生在我身上，我意识到下载 chromedriver 后我忘记将文件放在 python.exe 所在的同一目录中。通常，您可以通过 (C:) --> Users --> your User 找到您的 python.exe 文件，最后是 anaconda3 目录（考虑到您已经安装了我强烈推荐的 anaconda 包）。将您的 chromedriver 文件放在 anaconda3 目录中，该目录与您可以找到 python.exe 的位置完全相同。就是这样！这样做之后，我可以毫无问题地运行我的代码。 来自巴西的问候！ ;)

西尔维娅，试试

C:/Users/silvia/Desktop/executables/chromedriver

或任何你的硬盘名称

Answer 3

不提供可执行路径：

你可以使用webdriver_manage（通过pip install webdriver_manager安装）

from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from webdriver_manager.chrome import ChromeDriverManager

chrome_options = Options()
chrome_options.add_argument("--headless")
driver = webdriver.Chrome(ChromeDriverManager().install(), chrome_options=chrome_options)
