Question

我有一个角度项目，在https://update.angular.io/#7.2:9.0

之后，我从7.2升级到了9。

升级后，除了MatDialog之外的所有东西都在工作。打开对话框将显示一个不成比例的空白弹出窗口，控制台中显示以下错误。

core.js:3866 ERROR Error: Uncaught (in promise): TypeError: Cannot read property "hasAttached" of undefined

我已经从本教程https://www.techiediaries.com/angular-material-dialogs/中验证了使用带有自定义组件的对话框的方法是相同的。由于工作政策，我无法提供实际的代码。

根据this link，我还尝试退出常春藤思考是否是造成此问题的原因。但这没有帮助。

你们中有人也遇到过类似的问题吗？

问题解决了。我必须将Angular Material CDK升级到9.1，并将所有导入引用更改为新格式：

class CaseController extends Controller
{
    public function __construct()
    {
        $this->middleware('role',['except' => 'caseUrlView']);


    }
    public function index()
    {
        $data['portal'] = Portal::all();
        $data['operators'] = Operator::all();

        return view('cases::case', $data);
    }

一切都好！

将Angular更新到版本9
