python - ChromeDriver 假设 Chrome 在传递配置文件参数时崩溃了

Question

如果任何 Chrome 进程正在运行并且运行以下代码，Stack Overflow 将永远加载:

options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\\Users\\RvBVakama\\AppData\\Local\\Google\\Chrome\\User Data")
options.add_argument('--profile-directory=Profile 1')
w = webdriver.Chrome('C:/Program Files (x86)/Google/Chrome/Application/chromedriver.exe', options=options)

w.get("https://stackoverflow.com/")

如果存在任何 Chrome 进程并且运行以下代码，它将在片刻后加载堆栈溢出:

w = webdriver.Chrome('C:/Program Files (x86)/Google/Chrome/Application/chromedriver.exe')

w.get("https://stackoverflow.com/")

唯一的区别是第一个代码块使用配置文件 1 启动 Chrome。

这是来自 block 一的错误日志:

  (The process started from chrome location C:\Program Files (x86)\Google\Chrome\Application\chrome.exe is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

注意最后一行。

我不确定为什么 chromedriver 认为 Chrome 已崩溃。

Answer 1

好的，修复方法是转到 C:\Users\NAME\AppData\Local\Google\Chrome 并复制您的“用户数据”文件夹并为其指定另一个名称。 然后只需将“user-data-dir”参数设置为新文件夹即可。

# set up the chrome options to launch with the AUTO profile
options = webdriver.ChromeOptions()
options.add_argument("user-data-dir=C:\\Users\\RvBVakama\\AppData\\Local\\Google\\Chrome\\User Data AUTO")
options.add_argument('--profile-directory=Profile 1')
# start chrome with the driver
w = webdriver.Chrome('C:/Program Files (x86)/Google/Chrome/Application/chromedriver.exe', options=options)
