1. 在使用 chrome 驱动程序的本地机器上运行脚本时，出现以下错误，但同一脚本在 firefox 上运行良好。我正在使用 selenium-java 2.48.2 和 chrome 驱动程序 2.20

Answer 1

我有类似的错误并添加以下依赖项解决了它 -

      <dependency>
      <groupId>org.seleniumhq.selenium</groupId>
      <artifactId>selenium-remote-driver</artifactId>
      <version>2.48.2</version>
      </dependency>

扫描堆栈跟踪并找到错误的类帮助我分析出我当前的类版本不是最新的。
