我已经查看了这个问题的所有可用主题，但没有得到任何准确的答案......有人清楚备份 .sql 文件中的当前数据库并下载它吗？

我已经在我的 Laravel + vue 项目中使用 npm 安装了 AminLte v3，所有东西都运行良好，但是当我单击标记为的侧导航栏主菜单时

<li class="nav-item has-treeview">
    <a href="#" class="nav-link">
        <i class="nav-icon fas fa-users"></i>
        <p>
            Members
            <i class="fas fa-angle-left right"></i>
            <span class="badge badge-warning right">new:2</span>
        </p>
    </a>
    <ul class="nav nav-treeview">
        <li class="nav-item">
            <router-link :to="{name : 'members'}" class="nav-link">
                <i class="fas fa-user-check nav-icon"></i>

                <span class="badge badge-danger right">2</span>
                <p>Latest</p>
            </router-link>

当我尝试从 React Native 模块调用函数时，它给我返回未知的错误：ReactNative：CatalystInstanceImpl 捕获本机异常 java.lang.RuntimeException：无法调用

当我使用 Handler(Looper) 方法添加实际函数时，如果我只是打印或控制台模块方法的某些内容，它就会工作，它会抛出错误

我下面的代码有什么问题？或者我错过了什么？

这是我的本机模块类

   package com.mosabeeapp;\nimport com.facebook.react.bridge.ReactApplicationContext;\nimport com.facebook.react.bridge.ReactContextBaseJavaModule;\nimport com.facebook.react.bridge.ReactMethod;\nimport com.printer.sdk.PrinterConstants;\nimport com.printer.sdk.PrinterInstance;\n\nimport android.annotation.SuppressLint;\nimport android.os.Handler;\nimport android.os.Looper;\nimport android.os.Message;\nimport android.util.Log;\n\nimport java.io.File;\n\npublic class CalendarModule extends ReactContextBaseJavaModule {\n    public PrinterInstance myPrinter;\n\n    private String devicesName;\n    private String devicesAddress;\n    private Integer baudrate;\n    private Boolean isConnected;\n\n    private Handler mHandler = new Handler() {\n        @SuppressLint("ShowToast")\n        @Override\n        public void handleMessage(Message msg) {\n\n            System.out.println("@@@@@@@@@@@@" + msg.what);\n            switch (msg.what) {\n                case PrinterConstants.Connect.SUCCESS:\n                    isConnected = true;\n                    System.out.println("isConnected status:::;" + isConnected);\n                    break;\n                case PrinterConstants.Connect.FAILED:\n …

我正在尝试将我的 Laravel 项目框架从 5.5 升级到 5.7，但无法做到..

当我将 composerjson requres 更改为 laravel 升级文档并在项目终端上点击composer update 时，它的输出是这些：

composer update
Do not run Composer as root/super user! See https://getcomposer.org/root for details

尝试设置会话 =>

Session::set('hello', "hello");

但出现这个错误

Call to undefined method Illuminate\Session\Store::set()

我该如何解决？
