所以我之前有一个Chromedriver / Selenium设置工作,但现在尝试在一台新机器上安装所有东西(64位
Linux)它给了我一些问题,并没有真正告诉我什么是绊倒.
我正在使用Selenium的独立服务器版本2.37.0和nodejs以及最新版本的Chromedriver(我也尝试过Chromedriver 2.0,我之前使用的早期版本,结果相同).
如下面的输出所示,当我尝试使用webdriver运行脚本时,我收到一个错误,其中包括：引起：org.openqa.selenium.WebDriverException：未知错误：Chrome无法启动：异常退出.我没有从chromedriver获得日志输出,只从Selenium输出(带错误)和Node.js输出(尝试运行测试脚本).
谁能让我知道我在这里做错了什么？
编辑：我忘了补充说,失败后有一个Chromedriver运行的过程,所以这件事是可以的,我的Chrome可执行文件确实在/ etc / bin / google-chrome,就像Chromedriver想要的那样.
输出：
一旦我启动并运行selenium,我就试图运行一个包含内容的简单测试脚本：
var webdriverjs = require("webdriverjs");
var client = webdriverjs.remote({desiredCapabilities:{browserName:"chrome"}}); // to run in chrome
client
.init()
.url("https://github.com/")
.end();
运行测试脚本的Node.js控制台输出如下所示：

最后,Selenium在启动时和尝试运行脚本时的输出如下.出于某种原因,我根本没有得到chromedriver.log文件.

解决方法
好的,在发布所有这些之后我才知道我做错了什么！
问题是我通过SSH从一个终端启动selenium,然后通过VNC从桌面终端运行测试脚本.显然Selenium,WebdriverJS或Chromedriver不喜欢这个.
当我启动Selenium并从桌面上的终端运行测试脚本时,它工作正常.
