使用 Chromedriver 制作程序，出现错误：“无法使用此命令获取 Chrome 版本”

Question

这是我的代码。我这样做是因为当我尝试放置 chromedriver.exe 的路径时，我要么得到“WebDriverException：消息：'chromedriver.exe'可执行文件可能有错误的权限”或“WebDriverException：消息：'chromedriver'可执行文件需要在 PATH 中”，我不知道如何解决它。

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager


browser = webdriver.Chrome(ChromeDriverManager().install())

运行此代码会出现以下错误：

ValueError: Could not get version for Chrome with this command: google-chrome --version

老实说，我完全不知道我能做些什么来解决这个问题。

Answer 1

这是 webdriver_manager link中的一个错误。

为了避免此问题，您可以使用 google-chrome-stable 浏览器而不是 chromium-browser。
