离子 2 - 错误在 Android Studio 中找不到已安装的 Gradle 版本 [英] ionic 2 - Error Could not find an installed version of Gradle either in Android Studio

问题描述

我创建了 ionic 2 项目并像这样添加了诊断cordova插件:

I create ionic 2 project and add diagnostic cordova plugin like this :

ionic plugin add cordova.plugins.diagnostic

npm install --save @ionic-native/diagnostic

并像这样添加android平台:

and add android platform like this :

ionic platform add android@latest

但是当使用 ionic build android 控制台构建时给我这个错误:

but when build with ionic build android console give me this error :

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

我尝试手动下载 gradle.3.3-all.zip 并在 platform/android/cordova/lib/builders/GradleBuilder.js 中更改此 distributionUrl var

and I try to download manualy gradle.3.3-all.zip and change this distributionUrl var in platform/android/cordova/lib/builders/GradleBuilder.js

 var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'https\://services.gradle.org/distributions/gradle-3.3-all.zip'

到:

var distributionUrl = process.env['CORDOVA_ANDROID_GRADLE_DISTRIBUTION_URL'] || 'file:///E:/gradles/gradle-3.3-all.zip';

但不工作，控制台给我最后一个错误.

but not working and console give me last error.

我不知道如何为 android@latest 版本添加 gradle

I dont know how to add gradle for android@latest version
