我创建了一个本地脚本vue模板：
sudo vue init nativescript-vue/vue-cli-template project
当我尝试使用命令tns run运行它时，出现以下错误：
Gradle build...

此外，在运行命令后，我还会收到一些警告。我安装了Android Studio，尝试正确设置JAVA_HOME变量，以及其他一些设置，但没有任何效果。
✖ The ANDROID_HOME environment variable is not set or it points to a non-existent directory. You will not be able to perform any build-related operations for Android.
To be able to perform Android build-related operations, set the `ANDROID_HOME` variable to point to the root of your Android SDK installation directory.
✖ WARNING: adb from the Android SDK is not installed or is not configured properly.
For Android-related operations, the NativeScript CLI will use a built-in version of adb.
To avoid possible issues with the native Android emulator, Genymotion or connected
Android devices, verify that you have installed the latest Android SDK and
its dependencies as described in http://developer.android.com/sdk/index.html#Requirements

答案 0 :(得分：0)
您已经安装了Android Studio，但由于错误2和tns所指出的，可能尚未设置Android环境变量ANDROID_SDK_ROOT。 您正在使用什么操作系统？
