更新angular-devkit并获取失败: Microsoft.AspNetCore.SpaServices[0]

Question

在我的Angular 8 +.net核心2.2中，我已经从Angular 8.2.1升级到8.2.7，之后我在控制台窗口中看到以下消息：

fail: Microsoft.AspNetCore.SpaServices[0]
      <s> [webpack.Progress] 10% building 1/1 modules 0 active

      i ｢wdm｣: Compiled successfully.

似乎应用程序已经编译并正常工作，我发现angular-devkit才是问题所在，如果我恢复到以前的版本，一切都很好：

"@angular-devkit/build-angular": "^0.803.5",

恢复为

"@angular-devkit/build-angular": "0.802.1",

使用最新版本有什么修复方法吗？

我在使用的时候遇到了和你一样的问题

"@angular-devkit/build-angular": "~0.803.3"

如果构建不成功，我总是会看到失败日志。在angular cli编译成功后，一切都会好起来的
