angular - 将 Angular 11 应用程序升级到 Angular 12 时遇到问题

Question

当我们尝试将 Angular 11 应用程序(单 SPA 微前端)更新到 Angular 12 时，我们面临以下问题。

尝试运行此应用时控制台出现错误:

An unhandled exception occurred: Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.

• configuration.output 有一个未知的属性“chunkLoadingGlobal”。这些属性是有效的:object { auxiliaryComment？，chunkCallbackName？，chunkFilename？，chunkLoadTimeout？，crossOriginLoading？，devtoolFallbackModuleFilenameTemplate？，devtoolLineToLine？ hotUpdateChunkFilename？，hotUpdateFunction？，hotUpdateMainFilename？，jsonpFunction？，jsonpScriptType？，library？，libraryExport？，libraryTarget？，path？，pathinfo？，publicPath？，sourceMapFilename？，sourcePrefix？，strictModuleExceptionHandling？，umdNamedDefine？，webassemblyModuleFilename？ }-> 影响编译输出的选项。 output 选项告诉 webpack 如何将编译后的文件写入磁盘。有关详细信息，请参阅“C:\Users\newUser\AppData\Local\Temp\ng-UOeNLu\angular-errors.log”。

我遇到了同样的问题。更改某些依赖项的版本和 package.json 中的 devDependencies 为我解决了这个问题。

更改依赖项以具有以下内容:

• "single-spa": "5.9.3"
• "single-spa-angular": "5.0.2"

将开发依赖项更改为具有以下内容:

• "@angular-builders/custom-webpack": "12.1.3"
• "@angular-devkit/build-angular": "12.2.16"
