python-3.x - Chrome Canary headless 模式在 Windows 10 上不起作用

Question

Google Chrome Canary 不适用于 Windows 上的 headless。

Chrome headless 不适用于 Windows。当我尝试执行以下代码时，错误发生如下。但它适用于非 headless 模式。

我知道 Canary 不稳定，但我想用它来学习 Web 高级规范。

这个错误是由金丝雀中的错误引起的？还是我的代码引起的？

代码:

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

op = Options()
op.binary_location = "C:\\Users\\username\\AppData\\Local\\Google\\Chrome SxS\\Application\\chrome.exe"
op.add_argument("--headless")
op.add_argument("--disable-gpu")

driver = webdriver.Chrome("chromedriver.exe", chrome_options=op)

driver.get("http://www.google.com")

错误:

由于您的错误日志报告如下:

[1205/232511.644:ERROR:gpu_process_transport_factory.cc(1017)] Lost UI shared context.
[1205/232511.644:ERROR:instance.cc(49)] Unable to locate service manifest for metrics
[1205/232511.644:ERROR:service_manager.cc(890)] Failed to resolve service name: metrics

我会建议以下步骤:

• 通过 Revo Uninstaller
从系统中卸载 Google Chrome Canary
• 使用 CCleaner 工具清除所有操作系统杂项。
• 安装全新的 Google Chrome Canary

• 使用以下代码块:

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  
  op = Options()
  op.binary_location = "C:\\Users\\username\\AppData\\Local\\Google\\Chrome SxS\\Application\\chrome.exe"
  op.add_argument("--headless")
  op.add_argument("--disable-gpu")
  driver = webdriver.Chrome(chrome_options=op, executable_path=r'C:\path\to\chromedriver.exe')
  driver.get("http://google.com/")
