NativeScript Linux安装程序（安装Android SDK平台28个软件包）失败

在正式安装Linux的NativeScript（）之后，您将进入步骤6：安装Android SDK平台的所有软件包28。

如果您只是像这样将上述命令粘贴到CLI中：

sudo $ANDROID_HOME/tools/bin/sdkmanager "tools" "emulator" "platform-tools" "platforms;android-28" "build-tools;28.0.3" "extras;android;m2repository" "extras;google;m2repository"

sudo $ANDROID_HOME/tools/bin/sdkmanager --sdk_root=${ANDROID_HOME} "tools" "emulator" "platform-tools" "platforms;android-28" "build-tools;28.0.3" "extras;android;m2repository" "extras;google;m2repository"

它将因以下警告而失败：

Warning: Could not create settings
java.lang.IllegalArgumentException

    at com.android.sdklib.tool.sdkmanager.SdkManagerCliSettings.createSettings(SdkManagerCliSettings.java:152)

警告：无法创建设置

解决方案是在步骤3（）设置ANDROID_HOME环境变量后，将以下标志添加到命令

--sdk_root=${ANDROID_HOME}

这似乎是sdkmanager查找SDK安装文件夹的方式存在缺陷。整个命令如下所示：

sudo $ANDROID_HOME/tools/bin/sdkmanager "tools" "emulator" "platform-tools" "platforms;android-28" "build-tools;28.0.3" "extras;android;m2repository" "extras;google;m2repository"

sudo $ANDROID_HOME/tools/bin/sdkmanager --sdk_root=${ANDROID_HOME} "tools" "emulator" "platform-tools" "platforms;android-28" "build-tools;28.0.3" "extras;android;m2repository" "extras;google;m2repository"
