Question

我一直在用＃34; dotnet new angular＆＃34;来解决很多webpack错误。项目（Angular 4，Dotnet Core 2.0.0）。

我的项目在开发中运作良好。但是，当我尝试做一个＆＃34; dotnet发布＆＃34;它正在使用＆＃34; webpack --env.prod＆＃34;这导致我的问题。我认为这与AOT有关。最后一个问题超出了我的范围，我找不到导致此错误：

    ERROR in ./ClientApp/boot.browser.ts

这是我的webpack.config.js文件：

还有什么我应该看的吗？

Answer 1

这可以通过替换

来解决

{ test: /\.ts$/, use: isDevBuild ? ['awesome-typescript-loader?silent=true', 'angular2-template-loader'] : '@ngtools/webpack' },

与

{ test: /(?:\.ngfactory\.js|\.ngstyle\.js|\.ts)$/, include: [/ClientApp/, /\$\$_gendir/], use: isDevBuild ? ['awesome-typescript-loader?silent=true', 'angular2-template-loader'] : '@ngtools/webpack' },

如果您一直在更新为角度5，则还需要将AotPlugin替换为AngularCompilerPlugin（这基本上是文件中的搜索和替换）
