Chrome 使用 chromedriver2.9 在 CentOS 上启动失败

【中文标题】Chrome 使用 chromedriver2.9 在 CentOS 上启动失败

【英文标题】：Chrome failed to start on CentOS using chromedriver2.9

【发布时间】：2014-07-02 10:30:59

【问题描述】：

环境：chromedriver 2.9、google-chrome-stable 34、python 2.6、CentOS6.4 final x86_64

我按照install-chrome.sh 安装 google-chrome-stable（不是 chromium）。它可能会从fedoraproject 中提取软件包并将这些软件包安装到/opt/google/chrome/lib。我按照link 安装chromedriver2.9。我可以手动运行 google-chrome 和 chromedriver 而不会出错。我通过pip install selenium(selenium 2.41) 安装 selenium。 Selenium 安装到/usr/lib/python2.6/site-packages/。以这种方式安装的 Google-chrome 似乎不允许以 root 身份打开。

当我在 python 控制台下以非 root 用户运行代码时：

>>> from selenium import webdriver
>>> driver = webdriver.Chrome()

它返回错误消息如下而不是打开chrome。

Traceback (most recent call last):
  File "<stdin>", line 3, in <module>

    raise exception_class(message, screen, stacktrace)

我得到日志跟随链接Unknown error: Chrome failed to start: exited abnormally。该链接上没有解决方案。我该怎么办？谢谢。

我也对那些DevTools 的事情感到困惑。

【问题讨论】：

我错过了什么吗？你是说 Selenium WebDriver 2.9.0 吗？这是令人难以置信的旧版本库。

我下载了chromedriver here。它应该是最新的。

抱歉，Chromedriver 2.9。不是webdriver2.9。我已经编辑过了。

尝试用this简单说明安装谷歌浏览器。

【参考方案1】：

你在使用无头吗？如果是这样，您将不得不通过pyvirtualdisplay 指定无头显示。

当我在没有告诉 selenium 使用视觉显示的情况下运行 selenium 时，我遇到了同样的错误（日志）。安装pyvirtualdisplay后，以下代码对我有用：

from selenium import webdriver
from pyvirtualdisplay import Display

display = Display(visible=0, size=(800, 600))
display.start()
driver = webdriver.Chrome()
driver.get("http://www.google.com")
print driver.page_source.encode('utf-8')
driver.quit()
display.stop()
