我正在尝试使用nativescript-dev-appium进行e2e测试，但失败了。我不知道怎么了 我正在使用此链接进行编码 https://github.com/NativeScript/ns-dev-days-appium-plugin

这是android28

"android28": {
        "platformName": "Android","platformVersion": "28","deviceName": "Emulator-Api28-Google","avd": "Emulator-Api28-Google","lt": 60000,"newCommandTimeout": 720,"noReset": false,"fullReset": false,"app": ""
    }

  

$ npm run e2e---runType android28

@ e2e /appium-demo node ./node_modules/nativescript-dev-appium/check-dev-deps.js &&  tsc -p e2e  &&  mocha --opts ./e2e/config/mocha.opts  "--runType" "android28"
