Ionic4 构建 android

Question

我想为 android 构建我的离子应用程序，但我有一个错误。

Checking Java JDK and Android SDK versions
ANDROID_SDK_ROOT=undefined (recommended setting)
ANDROID_HOME=C:\Users\masmas\AppData\Local\Android\sdk (DEPRECATED)
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
[ERROR] An error occurred while running subprocess cordova.

        cordova.cmd build android --release exited with exit code 1.

        Re-running this command with the --verbose flag may provide more information.

Answer 1

您必须手动安装 Gradle，因为最新版本的 android studio 不支持 gradle 从外部构建 sources.To 安装 gradle:- https://gradle.org/install/.
