刚开始使用聚合物和单元测试。我正在尝试此页面上的活动https://www.polymer-project.org/2.0/docs/tools/tests但我无法polymer test
运行。所以我尝试运行polymer test --verbose
并最终收到此错误:
Error: Selenium server did not start.Another Selenium process may already be running or your java version may be out of date.
error: cli runtime exception: Error: Selenium server did not start.Another Selenium process may already be running or your java version may be out of date.
