Question

我有一个Python（3.5）脚本，在无头Debian（9）服务器上使用Selenium（3.12），chromedriver（2.39）和谷歌Chrome（67）。

Python安装在virtualenv。

中

大约50％的时间脚本运行没有错误。另外50％我得到以下错误。这只是一个简单的ol＆＃39; chrome / chromedriver中的错误（这两个版本都是谷歌的最新版本）还是可能与我的设置/代码有关？

我的代码非常标准：

options = webdriver.ChromeOptions()                                                                                                                                                                        
options.add_argument('headless')                                                                                                                                                                           
options.binary_location='/usr/bin/google-chrome-stable'                                                                                                                                                                                                                                                                                                                                        
options.add_argument('window-size={}x{}'.format(*self.window_size))                                                                                                                                                                                                                                                                          
self.driver = webdriver.Chrome(chrome_options=options)

当您使用 Debian服务器并使用 无头Chrome 时，您需要将 WebDriver 实例配置为如下：

from selenium import webdriver

options = webdriver.ChromeOptions()
options.binary_location='/usr/bin/google-chrome-stable'
options.add_argument('--headless')
options.add_argument('--start-maximized') 
options.add_argument('disable-infobars')
options.add_argument('--disable-extensions')
options.add_argument('--no-sandbox')
options.add_argument('--disable-dev-shm-usage')
options.add_argument('window-size={}x{}'.format(*self.window_size))                                                                                                                                                                                                                                                                          
self.driver = webdriver.Chrome(chrome_options=options, executable_path='/path/to/chromedriver')
