如果任何Chrome进程正在运行并且运行以下代码,堆栈溢出将从不加载:
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,它将在几分钟后加载堆栈溢出:
^{pr2}$唯一的区别是第一个代码块使用profile1启动Chrome。在
以下是块1的错误日志:

注意最后一行。
我不确定为什么chromedriver认为Chrome已经崩溃了。在
我不确定这是同一个用户数据目录,但不同的配置文件会导致冲突。我总是在脚本中使用另一个用户数据目录。在
但看了你的案子我想是的。在
顺便说一句,为了让生活更轻松,为什么不直接复制到一个较短的目录地址?-说“C:\ChromeUserData”。在
如果您不关心旧的设置,只需指定user data dir到一个新位置。Chrome将为您创建个人资料和其他东西。(指定的目录必须存在。)
例如:
假设D:\chromedriver\UserDataDir存在(或者您先创建它) 以及chromedriver.exe位于D:\chromedriver\chromedriver.exe。在
这样,您就不需要再指定配置文件目录了。脚本将在
D:\\chromedriver\\UserDataDir
中创建和使用默认目录/配置文件,并保存您所做的任何更改。在另一个提示:你可以chromedriver.exe在目录中python.exe,从而节省了指定可执行路径的需要,也会减少可能出现的错误。在
为了使其更可靠,您可以将这些放在上面的代码片段之前:
^{2}$好的,所以修复方法是转到C:\Users\NAME\AppData\Local\Google\Chrome,复制“User Data”文件夹并给它另一个名称。 然后只需将“user data dir”参数设置为新文件夹。在
