Question

我有一个问题，每一次，时间基本上这是我的代码：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.binary_location = "C:\Program Files (x86)\Google\Chrome Beta\Application\chrome.exe"
options.add_argument("--no-sandbox")
options.add_argument("--no-default-browser-check")
options.add_argument("--no-first-run")
options.add_argument("--disable-default-apps")
driver = webdriver.Chrome(options=options, executable_path="C:\Program Files (x86)\Google\Chrome Beta\Application\chromedriver.exe")
driver.get('https://www.youtube.com/')

，错误是

selenium.common.exceptions.SessionNotCreatedException: Message: session not created

我使用了Pycharm，并尝试将VS代码与python 3.4、3.7和3.8.3结合使用请帮助我，我对此已经感到厌倦了。

完整错误日志：

Answer 1

您的错误不是

无法将消息发送到渲染器

如您所说。根据堆栈跟踪，您将问题发布到了第6行

driver = webdriver.Chrome(options=options, executable_path="chromedriver.exe", )

问题是：

selenium.common.exceptions.SessionNotCreatedException: Message: session not created

似乎您为chromedriver指定了无效的路径，而Selenium无法初始化驱动程序并创建会话。您还应该check the version of the chromedriver with the guide。 Here您可以下载有效版本（我已从堆栈跟踪中获取Chrome版本）。

Answer 2

是的，它确实开始了，然后关闭了上面的错误日志，而且我的版本正确

selenium.common.exceptions.SessionNotCreatedException：消息：会话未创建，Selenium python
