Chrome Canary无头模式在Windows10上不起作用

Question

Google Chrome Canary does not work with headless on Windows.

Chrome headless does not work on windows. The Error happens like following when I tried to execute below code. But it works on non-headless mode.

I know Canary is unstable but I want to using it to learning about web advanced spec.

This error caused by bug in canary? Or caused by my code?

code:

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")

Error:

As your error logs reports as follows :

[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

I will suggest the following steps :

• Uninstall Google Chrome Canary from your system through Revo Uninstaller
• Use CCleaner tool to wipe off all the OS chores.
• Install fresh Google Chrome Canary

• Use the following code block :

   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/")
