ChromeDriver假设传递配置文件参数时Chrome已崩溃

Question

如果任何Chrome进程正在运行并且以下代码正在运行，则Stack Overflow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进程并运行了以下代码，则它会加载片刻后溢出：

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

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

唯一的差异是第一个代码块以配置文件1启动Chrome。

这是第一块的错误日志：

注意最后一行。

我不确定为何chromedriver认为Chrome崩溃了。

Answer 1

我不确定它是否是相同的user-data-dir，但是不同的配置文件会导致冲突。我总是将另一个user-data-dir与脚本一起使用。

-但是看到您的情况，我想是这样。

顺便说一句，顺便说一句，为了使生活更轻松，为什么不只复制到一些较短的目录地址呢？ ---说“ C：\ ChromeUserData”。

如果您不关心旧设置，只需将user-data-dir指定到新位置即可。 Chrome会为您创建个人资料和其他内容。 （指定的目录必须存在。）

例如：

options = webdriver.ChromeOptions()
options.add_argument("--user-data-dir=D:\\chromedriver\\UserDataDir") #Path to your chrome user-data/profile
options.add_argument('--disable-infobars') #disable the automation prompt bar
options.add_argument('--lang=en') #Set language to English
w = webdriver.Chrome(executable_path="D:\\chromedriver\\chromedriver.exe", chrome_options=options)

鉴于 D：\ chromedriver \ UserDataDir 存在（或您先创建它） chromedriver.exe位于 D：\ chromedriver \ chromedriver.exe 。

通过这种方式，您不再需要指定配置文件目录。该脚本将在D:\\chromedriver\\UserDataDir内创建并使用默认目录/配置文件，并保存您所做的所有更改。

另一个提示：您可以将chromedriver.exe放在python.exe目录中，从而节省了指定execute_path的需求，也减少了可能的错误。

为使其更可靠，您可以在代码片段上方之前放置

：

import os
uddPath = 'D:\\chromedriver\\UserDataDir'
if not os.path.exists(uddPath):
    os.makedirs(uddPath)

Answer 2

好的，解决方法是转到C：\ Users \ NAME \ AppData \ Local \ Google \ Chrome，然后复制“ User Data”文件夹并给它起另一个名字。 然后只需将“ user-data-dir”参数设置为新文件夹。

# 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)
