错误如下：

1 Error: Could not find an installed version of Gradle either in Android Studio,
2 or on your system to install the gradle wrapper. Please include gradle
3 in your path, or install Android Studio

解决方案：

• 1、手动下载gradle

gradle-x.x-bin.zip （x.x代表版本） 
根据需要下载某一版本 
地址： 
(https://services.gradle.org/distributions)

• 2、添加环境变量

PATH=C:\Program Files\gradle-x.x\bin

• 3、关闭cmd或powershell窗口
• 4、重新打开，输入gradle -v，查看gradle安装成功与否
• 5、重新build
