Webpack:无法找到带ID的模块:main - (Aurelia App)

问题描述 投票:1回答:1

TLDR:与webpack捆绑在一起的Aurelia应用程序无法在浏览器中加载 - 控制台显示错误:can't find module with id: main。我认为这意味着它无法找到入口点。耗尽的东西尝试。


  • 我在Aurelia应用程序上工作。
  • 我们使用webpack捆绑我们的前端代码。
  • 这一切都很有效,直到过去几天。 (最近我们添加了aurelia-dialog,它运行良好,但我们必须做一些npm更新才能让它工作,等等)
  • 有几个npm依赖问题需要解决,但我最终得到了它们......
  • 一个特别恼人的是,gulp曾经被包含在我们的package.json中作为"gulp": "github:gulpjs/gulp#4.0,但我想git分支被删除了,所以在它和其他任何npm问题之间,它们都需要更新到"gulp": "4.0"这是一种寒意 - 除了它然后导致我们去,并且必须开始可怕的npm依赖性解决方案的长列车。
  • 但是,现在我陷入了npm包没有错误的地步,也没有来自webpack编译过程的错误,也没有任何tslint错误。然而,应用程序被破坏了,即使在其他没有被触及的分支中,也存在问题。

错误是:

错误:无法找到ID为:main的模块

在WebpackLoader。 (Qazxswpoi)

在步骤(https://localhost:44399/dist/app.bundle.js?v=18.11.05&v=QnXnhS1zNjvTNWq1CN7QzBCr2ti1BVIVEjGB_ewbuj0:9435:35

如果我理解正确(我不是设置此应用程序的开发人员,并且他已经不在了),则错误中引用的“main”来自https://localhost:44399/dist/app.bundle.js?v=18.11.05&v=QnXnhS1zNjvTNWq1CN7QzBCr2ti1BVIVEjGB_ewbuj0:9296:23aurelia-app="main"元素中的<body>属性:

(参见目录结构的底部)

index.html

wwwroot/dist/index.html

价值“主”,我相信应该参考<html> <head> <meta charset="utf-8"> <title>Aurelia Navigation Skeleton</title> <meta name="viewport" content="width=device-width, initial-scale=1"> <base href="/"> <!-- imported CSS are concatenated and added automatically --> </head> <body aurelia-app="main"> <script type="text/javascript" src="/app.bundle.js"></script><script type="text/javascript" src="/vendor.bundle.js"></script></body> </html>

(我已经尝试将它改为:src/main.tsmain.tssrc/main.tssrc/main等 - 它们都没有工作甚至改变了错误信息,这让我觉得这不是正确的地方。)

main.ts

../../src/main.ts

我相当肯定,它没有任何错误 - 因为它在上周末工作正常并且从那以后没有改变。

一个值得注意的事情是我们改变了webpack.config.js中的ModuleDependenciesPlugin部分。我们添加了一个条目:// we want font-awesome to load as soon as possible to show the fa-spinner import {Aurelia} from 'aurelia-framework' import environment from './environment'; import {PLATFORM} from 'aurelia-pal'; import * as Bluebird from 'bluebird'; // remove if you don't want a Promise polyfill (remove also from webpack.config.js) Bluebird.config({ warnings: { wForgottenReturn: false } }); export function configure(aurelia: Aurelia) { aurelia.use .standardConfiguration() .plugin(PLATFORM.moduleName('aurelia-dialog')) //.feature(PLATFORM.moduleName('resources/index')) //.plugin(PLATFORM.moduleName('aurelia-ui-virtualization')) .globalResources( [ //Converters PLATFORM.moduleName('converters/decimal-format'), PLATFORM.moduleName('converters/unit-selection-format'), PLATFORM.moduleName('converters/sort'), PLATFORM.moduleName('converters/date-format'), //Custom Element Registrations //base-level components (standalone) //PLATFORM.moduleName('components/custom-elements/table-cell-text-element'), PLATFORM.moduleName('components/custom-elements/text-div-element'), PLATFORM.moduleName('components/custom-elements/icon-button-element'), PLATFORM.moduleName('components/custom-elements/checkbox-div-element'), PLATFORM.moduleName('components/custom-elements/range-selector-element'), PLATFORM.moduleName('components/custom-elements/unit-selector-element'), //mid-level components (groupings/dependent on others) PLATFORM.moduleName('components/custom-elements/content-header-element'), PLATFORM.moduleName('components/custom-elements/table-configurable-element'), PLATFORM.moduleName('components/custom-elements/table-tiered-element'), PLATFORM.moduleName('components/custom-elements/grid-selector-element'), //high-level components (groups of mid-level) PLATFORM.moduleName('components/custom-elements/grid-selector-group-element'), PLATFORM.moduleName('components/custom-elements/dropdown-select-element'), PLATFORM.moduleName('components/custom-elements/alert-element'), //Rate Components PLATFORM.moduleName('components/custom-elements/base-charge-element'), PLATFORM.moduleName('components/custom-elements/tiered-rate-element'), PLATFORM.moduleName('components/custom-elements/tiered-per-unit-charge-element'), PLATFORM.moduleName('components/custom-elements/rate-component-element'), PLATFORM.moduleName('components/custom-elements/meter-charge-element') ]); // Uncomment the line below to enable animation. // aurelia.use.plugin(PLATFORM.moduleName('aurelia-animator-css')); // if the css animator is enabled, add swap-order="after" to all router-view elements // Anyone wanting to use HTMLImports to load views, will need to install the following plugin. // aurelia.use.plugin(PLATFORM.moduleName('aurelia-html-import-template-loader')); if (environment.debug) { aurelia.use.developmentLogging(); } if (environment.testing) { aurelia.use.plugin(PLATFORM.moduleName('aurelia-testing')); } aurelia.start().then(() => {aurelia.setRoot(PLATFORM.moduleName('app'))}); } ,这是从aurelia-dialog加载自定义组件所必需的(见下文)。此更改最初没有破坏应用程序。我会说,它工作正常一个星期左右?

我的同事和我都花了几天时间试图让它弄明白 - 所以任何帮助都表示赞赏。

我已经尝试重置所有更改(包括在添加aurelia-dialog之前返回),尝试更改aurelia-app属性的值。清理并重建了几次。重新启动计算机。重新克隆了存储库....

在调试会话之后,通过将Webpack AureliaPlugin更改为最简单的形式,可以解决WebUIFinal/ ├── wwwroot/ │ └── dist/ │ ├── index.html │ ├── 0.chunk.js │ ├── ... │ ├── vendor.bundle.js │ └── app.bundle.js ├── aurelia-project/ │ └── aurelia.json ├── src/ │ ├── app.ts │ └── main.ts ├── package.json └── webpack.config.js (plus a bunch of other stuff, of course -- this is just what I deemed relevant) 的问题:

module with ID: main not found

由于构建的代码采用Webpack可以轻松理解的格式,因此无需任何配置。

此外,它更容易调试。如果main中的plugins: [ new AureliaPlugin() ] 函数包含在try catch或者承诺的configure中,那么你可以看到任何问题,而不是静默失败和永远加载的屏幕。


使用最新版本的对话框,您不必再手动包含catch(ex =>)用于对话框,因为它使用动态导入API,Webpack自然可以理解。所以我建议回到原来的那个,并删除该配置。
