我已经看到有关这个问题的问题，但似乎没有一个像我的。
当我执行以下命令时，突然间，突然间，开始出现此错误：
% sudo ionic cordova run android --release
输出：

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

[ERROR] An error occurred while running cordova run android --release (exit code 1).
但最糟糕的是，我有Gradle，在SDK和Android Studio模板中，老实说我不知道还能做什么，我一直试图弄清楚问题是什么，我不能做它好几天了。
这是我的环境，如果有人可以帮助我的话：
% sudo ionic info
cli packages: (/usr/local/lib/node_modules)
@ionic/cli-utils : 1.19.1

我有Gradle：

我是否对另一个项目（同一台机器）的要求显示gradle安装好了：
Requirements check results for android:
Java JDK: installed 1.8.0

Gradle: installed /Applications/Android Studio.app/Contents/gradle/gradle-4.1/bin/gradle
有些人说要安装gradle，但这没有任何意义，因为它已经安装，并且它正在工作。
它应该是关于权限的任何内容吗？我不知道还有什么建议吗？
