Ionic：無法構建android

Question

嘗試使用Ionic構建至android時遇到了大問題。 我最初嘗試正常的ionic build android ，但失敗了

[Error: ANDROID_HOME is not set and "android" command not in your PATH. You must fulfill at least one of these conditions.]

我在堆棧溢出和離子論壇上進行了一些搜尋，並安裝了Java和Android Studio作為“解決方案”，它開始安裝大量.jar文件，這發生了：

 Download https://repo1.maven.org/maven2/commons-logging/commons-logging/1.1.1/commons-logging-1.1.1.jar


    Download https://repo1.maven.org/maven2/commons-codec/commons-codec/1.4/commons-codec-1.4.jar


    Download https://repo1.maven.org/maven2/com/android/tools/external/lombok/lombok-ast/0.2.3/lombok-ast-0.2.3.jar


    Download https://repo1.maven.org/maven2/org/abego/treelayout/org.abego.treelayout.core/1.0.1/org.abego.treelayout.core-1.0.1.jar




    FAILURE: Build failed with an exception.

    * What went wrong:
    A problem occurred configuring root project 'android'.
    > failed to find target with hash string 'android-23' in: /Users/.../Library/Android/sdk

    * Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

    Error: /users/nick/documents/.../.../platforms/android/gradlew: Command failed with exit code 1 Error output:

    Please install Android target: "android-23".

    Hint: Open the SDK manager by running: /Users/.../Library/Android/sdk/tools/android
    You will require:
    1. "SDK Platform" for android-23
    2. "Android SDK Platform-tools (latest)
    3. "Android SDK Build-tools" (latest)

有什么建議嗎？ 也許我需要卸載Android Studio或其他東西？ 您可能會說，我對此很不好。 但這極大地阻礙了我正在從事的項目，因此如果有人可以提供幫助，那就太好了！

從安裝Android開發環境開始

根據Android SDK的位置配置ANDROID_HOME環境變量。 另外，考慮將ANDROID_HOME / tools和ANDROID_HOME / platform-tools添加到PATH。

對於Mac：

   export ANDROID_HOME=/<installation location>/android-sdk-macosx
  export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

對於Windows：

set ANDROID_HOME=C:\<installation location>\android-sdk-windows
set PATH=%PATH%;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools

對於Linux：

export ANDROID_HOME=/<installation location>/android-sdk-linux
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
