已尝试升级到visual studio 2017 v 15.6.0的专业版(预览7.0)

并安装了aspnetcore-runtime-2.1.0-preview1-final-win-x64和.net core SDK 2.1.4.

当我创建一个新的Web应用程序时,我收到一个错误说

"目前的.NET SDK不支持.NET Core 2.1.目标是.NET Core 2.0或更低版本,或者使用支持.NET Core 2.1的.NET SDK版本."

当我尝试构建现有项目时,我收到错误

"目前的.NET SDK不支持.NET Core 2.1.目标是.NET Core 2.0或更低版本,或者使用支持.NET Core 2.1的.NET SDK版本."

我在目标框架中没有看到".net core 2.1"

我的计算机中没有global.json文件

当我尝试dotnet --info时,我明白了

c:\ source\dnacloud\testapp> dotnet --info .NET命令行工具(2.1.100)

错误信息是 html-webpack-plugin 错误

仅在捆绑生产时才会出现此错误

当@ngtools/webpack 被 angular-router-loader、angular2-template-loader 和 awesome-typescript-loader 替换时，应用程序会正确捆绑

环境

Angular 8，webpack 4，html-webpack-plugin 3.2.0，打字稿：3.7.5
