无法安装selenium webdriver管理器

Question

我像往常一样尝试下面的代码为 chrom -windows 安装 selenium webdriver，但出现属性错误。我找不到其他人也发生过类似的问题。

输入：

# selenium 4
from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService
from webdriver_manager.chrome import ChromeDriverManager

预期输出：安装驱动程序

输出：

      3 from selenium.webdriver.chrome.service import Service as ChromeService
      4 from webdriver_manager.chrome import ChromeDriverManager
----> 6 driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install()))

我也遇到这个问题了。考虑到此 PR，这似乎是一个已知问题。 解决方法是指定应下载的版本。来自包的网站：

from webdriver_manager.chrome import ChromeDriverManager

ChromeDriverManager(driver_version="2.26").install()

我查看了源代码和最新的Chrome版本可以在这里找到。更全面的版本列表在这里。

所以，对你来说，这可能是这样的：

from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromeService
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(service=ChromeService(ChromeDriverManager(driver_version="2.26").install()))
