当我尝试在我的角度应用程序中使用MatToolBar时出现此错误。在浏览器中，我Uncaught TypeError: Object(...) is not a function在控制台中也收到警告：

WARNING in ./node_modules/@angular/cdk/esm5/text-field.es5.js 146:151-159
"export '??inject' was not found in '@angular/core'

WARNING in ./node_modules/@angular/cdk/esm5/a11y.es5.js 2324:206-214
"export '??inject' was not found in '@angular/core'

我该如何解决？在github上，这是一个封闭的问题。

我在我的应用程序中使用Angular 7，在开发服务器上运行它时出现错误。

我没有服务

但是我下面有错误

     (7.1.4). The local Angular CLI version is used.

     To disable this warning use "ng config -g cli.warnings.versionMismatch
     false".
