首先，项目工作正常，最近我在办公室里安装了新电脑，我需要从头开始配置eclipse和selenium。所以我下载了新版本并尝试执行现有项目。然后我stat得到错误。 当我使用selenium独立服务器3.0.1 jar文件时，我收到以下错误

如果我使用Selenium server 2.53.0，则会显示以下错误

不确定我做错了什么。我尝试卸载chrome并按照ChromeWebDriver - unknown error: Chrome failed to start: crashed中的说明重新安装它。还是行不通。 任何帮助，将不胜感激 感谢

2 个答案:

答案 0 :(得分：1)

基于以下错误消息：

java.io.IOException: The system cannot find the path specified 


java.lang.UnsatisfiedLinkError: Failed to create temporary file for /com/sun/jna/win32-x86-64/jnidispatch.dll library: Access is denied

看起来Eclipse正在尝试创建临时文件，但不能。尝试使用提升的权限运行Eclipse（即以管理员身份运行），看看是否仍然收到相同的错误消息。

答案 1 :(得分：-1)

在做了一些研究后，我能够运行代码而没有错误。我做的解决方案是创建新的java类，并命名为旧类，后跟1.并将代码复制到新类。我在代码使用的地方使用了新的类名，并从项目包中删除了旧类。 对于Chromedriver.exe停止工作的问题，我发现在我的任务管理器中有多个chromedriver实例并结束了所有实例。这帮助我顺利进行。
