问题描述
我已经在Macbook Pro上运行了它，因此，为了将其传输到服务器以供长期使用，我遇到了麻烦.服务器是Ubuntu 16.04(服务器)和Python 2.7.12.
I've got this running on my Macbook Pro, so in an attempt to transfer it to my server for prolonged use, I have run into a snag. Server is Ubuntu 16.04 (server) and Python 2.7.12.
我使用pip安装了最新版本的硒，以及最新版本的ChromeDriver.我可以从命令行开始(存在GPU错误，但似乎没有引起任何问题.)
I installed the latest version of selenium using pip, and the latest version of ChromeDriver. I can start it fine from the command line (there is a GPU error but it seems not to cause any problems.)
但是，当我尝试使用以下代码从python中启动它时:
However, when I try to start it from within python, using this code:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
path_to_chromedriver = '/usr/local/bin/chromedriver'
options = Options()
options.add_argument("start-maximized")
options.add_argument("--headless")
options.add_argument("--disable-gpu")
options.add_argument("--disable-extensions")
options.add_argument("--no-sandbox")
service_args = ['--verbose']
service_log_path = '/tmp/local/chromedriver.log'
driver = webdriver.Chrome(executable_path=path_to_chromedriver, chrome_options=options, service_args=service_args, service_log_path=service_log_path)
但是，当我启动时，这是我在chromedriver.log中得到的(在COMMAND InitSession的所有初始启动脚本之后:
However, when I start things up, here's what I get in the chromedriver.log (after all the initial startup script for COMMAND InitSession:
[0.998][INFO]: Launching chrome: /opt/google/chrome/google-chrome --disable-background-networking --disable-client-side-phishing-detection --disable-default-ap\
ps --disable-hang-monitor --disable-popup-blocking --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-automation --enable-logging --ign\
ore-certificate-errors --load-extension=/tmp/.org.chromium.Chromium.tPkUXa/internal --log-level=0 --metrics-recording-only --no-first-run --password-store=basi\

data:,
[0.998][DEBUG]: DevTools request: http://localhost:12752/json/version
[1.078][DEBUG]: DevTools request failed
它会继续吐出该错误消息约60秒钟，直到最终在Python中返回该错误消息:
And it continues to spit out that error message for about 60 seconds until it ultimately returns this in Python:
WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally
(Driver info: chromedriver=2.29.461571 (8a88bbe0775e2a23afda0ceaf2ef7ee74e822cc5),platform=Linux 4.4.0-116-generic x86_64)
我一生无法解决这个问题，因此我进行了广泛的搜索.
I cannot for the life of me figure out how to fix this, and I have searched extensively.
给我的印象是，如果我使用无头的话就不需要使用任何虚拟屏幕仿真，但这可能是问题所在吗? (我在没有Ubuntu的GUI的初始化模式下运行.)
I was under the impression that I didn't need to use any virtual screen emulation if I was using headless, but could that be the issue? (I'm running in an init mode w/o a GUI in Ubuntu.)
此外，我不喜欢在该命令中没有传递--headless以启动chrome-stable ...这是问题吗?
Also, I don't like that there's no --headless being passed in that command to start chrome-stable... is that an issue?
谢谢.
Chromedriver版本(我认为是最新版本):
Chromedriver version (I got what I thought was latest version):
$ chromedriver
Starting ChromeDriver 2.29.461571 (8a88bbe0775e2a23afda0ceaf2ef7ee74e822cc5) on port 9515
Only local connections are allowed.
硒
$ pip freeze | grep selenium
selenium==3.11.0
Chrome
$ google-chrome --version
Google Chrome 65.0.3325.162
这是显示正在发生什么情况的日志跟踪-它在DevTools故障中循环60秒然后死掉.
Here's the log trace that shows what's going on-- it loops on the DevTools failure for 60 seconds then dies.

推荐答案
您的chromedriver对于您的chrome版本已过期.您正在使用chromedriver=2.29.461571，但是与Chrome65兼容的最新版chromedriver是2.37
Your chromedriver is out of date for your version of chrome. You're using chromedriver=2.29.461571 but the latest version of chromedriver, which is compatible with Chrome65 is 2.37
