python - Chrome Web 驱动程序返回无效的 Chrome 版本

Question

我试图创建一个 Chrome 驱动程序的实例。它抱怨 Chrome 版本 91 不兼容：

Current browser version is 91.0.4472.114 with binary path /usr/bin/google-chrome

但是，当我检查提到的 Chrome 二进制文件的版本时，它说我安装了 92 版：

$ /usr/bin/google-chrome --version
Google Chrome 92.0.4515.131

看起来该消息具有误导性。可能是什么原因？

完整脚本：

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

options = webdriver.ChromeOptions()

options.add_experimental_option("prefs", prefs)
options.add_argument("--remote-debugging-port=9222")
options.add_argument("--headless")

driver = webdriver.Chrome(ChromeDriverManager().install(), options=options)

完整的堆栈跟踪：

编辑：删除以下行：

options.add_argument("--remote-debugging-port=9222")

解决了这个问题。更改端口也是如此。
