我创建ionic 2项目，并添加诊断cordova插件，如下所示:
ionic plugin add cordova.plugins.diagnostic
npm install --save @ionic-native/diagnostic
并像这样添加android平台:
ionic platform add android@latest
但当构建与ionic构建android控制台给我这个错误:
Error: Could not find an installed version of Gradle either in Android Studio,
or on your system to install the gradle wrapper. Please include gradle
in your path, or install Android Studio
我尝试下载手动gradle.3.3-all.zip，并在platform/android/cordova/lib/builders/GradleBuilder.js中更改这个distributionUrl变量
var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'https\\://services.gradle.org/distributions/gradle-3.3-all.zip'
to:
var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'file:///E:/gradles/gradle-3.3-all.zip';
但不工作和控制台给我最后一个错误。
我不知道如何为android@latest版本添加gradle
