帶有 Ionic 的 Cordova 無法檢測到 Java 或 Android Studio

Question

我開始使用帶有cordova的ionic並安裝了Android studio我安裝了所需版本的jdk並安裝了gradle現在我在做某事時遇到了3個問題

$ ionic cordova build --release android

第一的：

Checking Java JDK and Android SDK versions
ANDROID_SDK_ROOT=undefined (recommended setting)
ANDROID_HOME=C:\Users\\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.

第二個：

我不明白如何安裝或安裝 Android Studio，即使在手動設置 ANDROID_HOME 之后它也會從 Android Studio 中出現。

在 Linux 上，問題是他沒有從頭開始閱讀 Java，我在其他 3 台設備上嘗試了相同的問題，但遇到了不同的問題。

有時會出現一個錯誤，我必須安裝操作系統才能構建。
