更新 angular-devkit 并失败：Microsoft.AspNetCore.SpaServices[0]

Question

在我的 Angular 8 +.net core 2.2 中，我从 Angular 8.2.1 升级到 8.2.7，之后我在控制台窗口中看到消息：

fail: Microsoft.AspNetCore.SpaServices[0]

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

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

恢复

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

有没有使用最新版本的修复程序？

我使用的时候也遇到和你一样的问题

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

如果构建不成功，我总是会看到失败日志。Angular cli 编译成功后一切都会好起来的
