Question

我是Programmin的新学生，我正尝试首次使用Chromedriver和Selenium。我绝对无法访问下载的文件，也不知道为什么。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！我尝试使用反斜杠，双反斜杠和其他命令。也许我应该从头开始尝试整个过程！知道为什么不起作用吗？预先谢谢你！

这是错误消息：

我不知道你是否已经解决了这个问题，但这也发生在我身上，我意识到在下载 chromedriver 后我忘记把文件放在 python.exe 所在的同一个粘贴中。通常，您可以通过转到 (C:) --> 用户 --> 您的用户并最后粘贴 anaconda3 来找到您的 python.exe 文件（如果您安装了 anaconda 包，我强烈推荐）。将您的 chromedriver 文件放在 anaconda3 粘贴中，这与您可以找到 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！ ;)

西尔维亚，尝试

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

或您的硬盘名称

Answer 3

不提供可执行路径：

您可以使用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)
