could not start a new session on selenium webdriver
提问by Erin Zhang
I'm trying to open firefox browser using selenium java code.
我正在尝试使用 selenium java 代码打开 Firefox 浏览器。
System.setProperty("webdriver.gecko.driver", " System.setProperty("webdriver.gecko.driver", "C:/Program Files/Mozilla Firefox/geckodriver-v0.8.0-win32/geckodriver.exe");
WebDriver driver = new FirefoxDriver();
System.setProperty("webdriver.firefox.port","4444");
The Selenium server is up and running. I tried to change the selenium server port using command prompt and set the port in code, but neither of them works.
Selenium 服务器已启动并正在运行。我尝试使用命令提示符更改 selenium 服务器端口并在代码中设置端口，但它们都不起作用。
> Exception in thread "main" 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.

In the error message, "Connect to localhost:6544" it tried to connect to a different localhost everytime. Can anyone see where the problem is?
在错误消息“连接到本地主机：6544”中，它每次都尝试连接到不同的本地主机。谁能看出问题出在哪里？
The versions I'm using are:
我使用的版本是：
- firefox 48.0
- selenium 3.0.0 beta 2
- windows 7 32 bits
- geckodriver-v0.8.0-win32
- 火狐 48.0
- 硒 3.0.0 测试版 2
- 视窗 7 32 位
- geckodriver-v0.8.0-win32
Also my geckodriver executable isn't running, it says VCRUNTIME140.dill is missing and I should reinstall to fix the problem. But after I reinstalled it, same thing happened.
我的 geckodriver 可执行文件也没有运行，它说 VCRUNTIME140.dill 丢失，我应该重新安装以解决问题。但是在我重新安装它之后，同样的事情发生了。

Thanks for @Saurabh's suggestion, I downgraded my selenium to 2.53.1. The browser is opening now, but nothing shows up. And I got another error
感谢@Saurabh 的建议，我将 selenium 降级到 2.53.1。浏览器现在正在打开，但没有显示任何内容。我又犯了一个错误

You need to pass DesiredCapabilitieswith marionettecapability to trueinto FirefoxDriveras well as below :-
你需要通过DesiredCapabilities与marionette能力true成FirefoxDriver以及下文： -
System.setProperty("webdriver.gecko.driver", "C:/Program Files/Mozilla Firefox/geckodriver-v0.8.0-win32/geckodriver.exe");
//Now you can Initialize marionette driver to launch firefox
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new FirefoxDriver(capabilities);
Edited: If unfortunately above does not work, I would suggest you to downgrade your firefox to 45 or lessand use FirefoxDriveras below :-
编辑：如果不幸以上不起作用，我建议您将您的 firefox 降级到 45 或更低，并使用FirefoxDriver如下：-
WebDriver driver = new FirefoxDriver();
回答by Szabolcs Kovacs
Firstly make sure all jar files added, including from /lib folder too the following snippet code would open the browser with added http link. By the way, I used win7 64bit, so keep eyes on the geckodrive path.
首先确保添加了所有 jar 文件，包括来自 /lib 文件夹的以下代码片段将打开浏览器并添加 http 链接。顺便说一句，我使用的是 64 位的 win7，所以请留意 geckodrive 路径。
System.setProperty("webdriver.gecko.driver", "C:\Users\XYZ\Documents\geckodriver.exe");
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
try {
WebDriver driver = new FirefoxDriver();
driver.navigate().to("http://google.com");
} catch(Exception e) {
System.out.println(e);
}
