Firefox更新后无法使用Selenium打开浏览器

我在Ubuntu Desktop 16.04上使用Selenium WebDriver,并且无法打开浏览器。 Firefox更新后出现以下错误(在此之前,它一切正常):

Traceback (most recent call last):
  File "test.py", line 6, in <module>
    driver = webdriver.Firefox()
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/firefox/webdriver.py", line 81, in __init__
    self.binary, timeout)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/firefox/extension_connection.py", line 51, in __init__
    self.binary.launch_browser(self.profile, timeout=timeout)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/firefox/firefox_binary.py", line 68, in launch_browser
    self._wait_until_connectable(timeout=timeout)
  File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/firefox/firefox_binary.py", line 98, in _wait_until_connectable
    raise WebDriverException("The browser appears to have exited "
selenium.common.exceptions.WebDriverException: Message: The browser appears to have exited before we could connect. If you specified a log_file in the FirefoxBinary constructor, check it for details.

从Firefox版本47.0开始(一段时间后出现),由于此版本中引入了错误,因此必须使用新驱动程序(由mozilla而不是硒创建)连接到Firefox。 从Firefox 48.0版开始,旧的驱动程序将完全不再使用,只能使用Marionette,所以最好现在切换。 请参阅:适用于Firefox的Marionette Webdriver

下载驱动程序(在OSX只使用brew install geckodriver ),重命名可执行文件wires.exe在Windows,或wires上* nix系统,并确保可执行文件存在于系统路径,然后在你的程序中使用这个驱动程序,而旧驱动程序的使用如下:

当使用本地webdriver时:

蟒蛇:

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True

driver = webdriver.Firefox(capabilities=firefox_capabilities)

红宝石:

driver = Selenium::WebDriver.for :firefox, marionette: true

使用Javascript:

var capabilities = Capabilities.firefox();
capabilities.set('marionette', true);

var driver = new webdriver.Builder().withCapabilities(capabilities).build();

Java的:

DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
Webdriver driver = new FirefoxDriver(capabilities);

C#:

var driver = new FirefoxDriver(new FirefoxOptions());

使用硒网格时:

当使用硒网格时,驱动程序应该出现在网格中所有机器的路径上。

蟒蛇:

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
driver = webdriver.Firefox(capabilities=firefox_capabilities)

红宝石:

caps = Selenium::WebDriver::Remote::Capabilities.firefox marionette: true
driver = Selenium::WebDriver.for :firefox, desired_capabilities: caps

Java的:

DesiredCapabilities capabilities = DesiredCapabilities.firefox();
// Set Marionette on so the Grid will use this instead of normal FirefoxDriver
capabilities.setCapability("marionette", true);

WebDriver driver = new RemoteWebDriver(capabilities); 

C#:

DesiredCapabilities capabilities = DesiredCapabilities.Firefox();
// Set Marionette on so the Grid will use this instead of normal FirefoxDriver
capabilities.SetCapability("marionette", true);

var driver = new RemoteWebDriver(capabilities); 

固定 :此时的解决方案是降级Firefox! 运行此命令可获取可用Firefox版本的列表。

apt-cache show firefox | grep Version

我的结果:

Version: 47.0+build3-0ubuntu0.16.04.1
Version: 45.0.2+build1-0ubuntu1

安装:

sudo apt-get install firefox=45.0.2+build1-0ubuntu1

要保留此版本并禁止更新:

sudo apt-mark hold firefox

如果你想要保留firefox版本并允许更新:

sudo apt-mark unhold firefox
sudo apt-get upgrade

解决方案 :将Firefox升级到47.0.1,将Selenium升级到2.53.1。

这种组合对我有用。
