java无法在安卓 emu（Mac OS）上运行TestNG测试

Question

我似乎不明白为什么我的安卓测试无法执行。错误如下所示：

木卫一。阿皮姆。java_客户端。服务地方的InvalidServerInstanceException:发生了无效的服务器实例异常：没有安装节点！请通过NPM（https://www.npmjs.com/package/appium#using-node-js）或下载并安装Appium应用程序（http://appium.io/downloads.html）安装节点

我已经通过自制和网站安装了nodejs。 我已经在/bash用户配置文件中设置了环境变量。 我已卸载并重新安装了node/npm。 我已链接brew安装。 我可以手动启动appium服务器，并通过appium从应用程序获取XPath

节点-v8。11.1 npm-5.6.0

有什么建议吗

双重检查节点installation instructions

通过npm安装appium： npm install -g appium

安装&；启动appium doctor以检查环境设置： npm install appium-doctor appium-doctor

您应该检查输出并修复任何问题。至于Node.js它应该像这样打印smth：

info AppiumDoctor  ✔ The Node.js binary was found at: /usr/local/bin/node
info AppiumDoctor  ✔ Node version is 7.9.0
