当尝试在 AWS Lambda 函数内运行时，我不断收到以下错误：

darwin-x64' 二进制文件不能在 'linux-x64' 平台上使用。请删除“node_modules/sharp/vendor”目录并运行“npm install”

我使用 MacBook Pro 中的无服务器框架部署了无服务器应用程序。我该如何解决这个问题？

我正在尝试使用 AWS S3 预签名 URL 为 Vue 应用程序实现图片上传功能。第一步是向 API 发送请求，该 API 将创建签名 URL 来上传文件。这部分工作正常：

服务器端：

'use strict';

const aws = require('aws-sdk');
const config = require('../config');
const util = require('./util');
const uuidv4 = require('uuid/v4');

const bucketName = 'myAmazonS3Bucket';

aws.config.update({
  secretAccessKey: config.AWS_SECRET_ACCESS_KEY,
  accessKeyId: config.AWS_ACCESS_KEY_ID,
  region: 'us-west-2'
});

const s3 = new aws.S3({ signatureVersion: 'v4' });

const handler = async (event) => {
    console.log('Uploading file...');

    return await getUploadURL();
}

const getUploadURL = async () => {
    const actionId = uuidv4();

    const s3Params = …

我收到以下错误消息:

Global.asax中

public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();

            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles); …

当我在页面上使用JQuery Select2时它工作正常.但是,当它位于引导框对话框模式中时,它无法正确显示.

这是我正在使用的jquery代码...

$.ajax({
        type: 'GET',
        url: src,
        success: function (data) {
            if (allowed) {
                bootbox.dialog({
                    title: dialogTitle,
                    message: $('#altForm'),
                    onEscape: true,
                    show: false // We will show it manually later
                }).on('shown.bs.modal', function () {
                    $('#enterBtn').hide();
                    $('#userPwd').hide();
                    $('.app-ctrl').prop('disabled', true);
                    $('#altForm').show();
                }).on('hide.bs.modal', function (e) {
                    $('#altForm').hide().appendTo('body');
                }).modal('show');
                $('.boop').parents('.bootbox').removeAttr('tabindex');
                $('.boop').select2();
            }
        }
    });

我相信Select2下拉列表的代码是有效的,因为当我注释掉初始化行时:$('.boop').select2(); 选择下拉列表变为常规下拉列表.但我不知道为什么它显示不正确.
