我正在尝试通过运行以下命令在 android 设备（小米 Pocophone）上运行我的 ionic 应用程序：

离子科尔多瓦运行安卓

但是，我收到以下错误消息：

我的手机通过usb type c线正确连接，开发者模式已经打开，usb调试模式打开

我尝试重新启动 PC 并关闭无关的 IDE，例如 Laragon …

我有一组数据需要进行处理才能生成报告

以下是提供的数据样本

$arrival_data = [
    [
        "arrival_date" => "09-Dec-2020",
        "total_amount" => "10",
        "total_traveller" => 6
    ],
    [
        "arrival_date" => "09-Dec-2020",
        "total_amount" => "20",
        "total_traveller" => 6
    ],
    [
        "arrival_date" => "10-Dec-2020",
        "total_amount" => "40",
        "total_traveller" => 3
    ]
];

我想处理上面的数据，以便它将按“arrival_date”分组并对数据求和，以便数据显示如下

$arrival_data = [
    [
        "arrival_date" => "09-Dec-2020",
        "total_amount" => "30", // sum of 10 + 20
        "total_traveller" => 6
    ],
    [
        "arrival_date" => "10-Dec-2020",
        "total_amount" => "40",
        "total_traveller" => 3
    ]
];

我还没有设法使用 Laravel Collection 生成预期的输出，我能得到的最接近的输出如下

{
    "09-Dec-2020": 30,
    "10-Dec-2020": …
