我想通过铬运行硒。我写了这段代码：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument("start-maximized")
options.add_argument("disable-infobars")
options.add_argument("--disable-extensions")
options.add_argument("--disable-gpu")
options.add_argument("--disable-dev-shm-usage")
options.add_argument("--no-sandbox")
options.binary_location = "/snap/bin/chromium"
driver = webdriver.Chrome(chrome_options=options)

但这段代码会抛出一个错误：

selenium.common.exceptions.WebDriverException: Message: unknown error: DevToolsActivePort file doesn't exist
Stacktrace:
#0 0x55efd7355a23 <unknown>
#1 0x55efd6e20e18 <unknown>
#2 0x55efd6e46e12 <unknown>

正确版本的 chromedriver 位于 usr/bin 中。我究竟做错了什么？

我正在使用以下代码运行 python 3.9。当我运行脚本时，我收到错误消息。不知道我错过了什么。该元素称为用户名。
