Question

我正在尝试使用maven和我的jenkins服务器执行Appium黄瓜测试。我收到此错误。我已经安装了NodeJS + Plugin并重新启动了服务器。不过，我的詹金斯（Jenkins）工作仍然引发了我这个错误。这是我正在使用的错误日志和版本，如果有人可以帮助解决此问题，很高兴。

在5.097s中更新了1个程序包 npm 6.4.1 节点v10.15.3 appium v1.9.1 java“ 1.8.0_201”

此错误似乎是在告诉您您要在其上运行测试的Jenkins从站上未安装Node。尽管您可能已经在Jenkins中安装了NodeJS插件，但是您将需要使用要使用的节点版本来配置作业。

Jenkins ver无法识别Node Js。 2.138.3
