【问题描述】：

我正在尝试设置一个新的 Selenium 项目，但无法使 thinks 正常工作。我的环境：

OSX      : 10.12.4
Java     : 1.8.0_121
Selenium : 3.4.0
Gecko    : 0.16.1      ( located at /opt/garbage/geckodriver and on path )
Firefox  : 53.0.3

Java 代码

System.setProperty("webdriver.gecko.driver", "/opt/garbage/geckodriver");
System.setProperty("webdriver.firefox.marionette", "/opt/garbage/geckodriver");

WebDriver driver = new FirefoxDriver();  <--

driver.get("https://www.google.com");

在本例中，第 4 行将打开一个新的 Firefox 浏览器窗口，但几秒钟后会抛出以下堆栈：

org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.

    at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:104)

以及来自失败运行的 StdErr：

我可能配置错了什么？

编辑

我也尝试过使用以下功能 - 无需更改

DesiredCapabilities caps = new FirefoxOptions()//
        .setProfile(new FirefoxProfile())//
        .addTo(DesiredCapabilities.firefox());

WebDriver driver = new FirefoxDriver( caps );  <--

【问题讨论】：

将浏览器的驱动程序更新到最新版本。像 Cromer Cromedriver/ IEdriver
0.16.1 似乎是最新的驱动程序。 source.

【解决方案1】：

这段代码对我有用

System.setProperty("webdriver.gecko.driver", "/opt/garbage/geckodriver.exe");
`WebDriver driver = new FirefoxDriver();`  <--
 driver.get("https://www.google.com");

我的配置：

硒：3.4.0

壁虎：0.16.1
火狐：53.0.3

【讨论】：

删除这一属性没有任何变化。
