Angular 5 Material 5 MatTableDataSource …“’mat-card-title

TL; DR：将@ angular / core,@ angular / material和@ angular / CDK升级到版本5后,我突然无法使用与mat-card相关的标签.

我无法使所有依赖项都正确无法导入MatTableDataSource.我意识到我可以实现自己的DataSource like this,但是如果它在文档中,那么确实可以在没有这个黑客的情况下进行工作配置.实现我自己的DataSource也意味着丢失漂亮的可排序标头和过滤,这是我最常追求的.

我将项目升级到Angular 5思考材料也将升级,但事实并非如此.材料和CDK保持在“^ 2.0.0-beta.12”.

在npm安装后我看到了这些警告：

…但是ng build成功了,我的应用程序的其余部分在package.json中运行正常：

dependencies": {
        "@angular/animations": "^5.2.0","@angular/cdk": "^2.0.0-beta.12","@angular/common": "^5.2.0","@angular/compiler": "^5.2.0","@angular/core": "^5.2.0","@angular/forms": "^5.2.0","@angular/http": "^5.2.0","@angular/material": "^2.0.0-beta.12","@angular/platform-browser": "^5.2.0","@angular/platform-browser-dynamic": "^5.2.0","@angular/platform-server": "^5.2.0","@angular/router": "^5.2.0","@ng-bootstrap/ng-bootstrap": "1.0.0-beta.6","angular-material-prefix-updater": "0.0.6","angular2-flash-messages": "^1.0.8","angular2-jwt": "^0.2.3","core-js": "^2.5.3","moment": "^2.20.1","ng2-file-upload": "^1.3.0","ngx-pagination": "^3.0.3","quill": "^1.3.4","rxjs": "^5.5.6","zone.js": "^0.8.19"
      },"devDependencies": {
        "@angular/cli": "^1.6.3","@angular/compiler-cli": "^5.2.0","@angular/language-service": "^4.4.6","@types/jasmine": "^2.8.3","@types/jasminewd2": "^2.0.3","@types/node": "^6.0.96","codelyzer": "~3.0.1","jasmine-core": "~2.6.2","jasmine-spec-reporter": "~4.1.0","karma": "^1.7.1","karma-chrome-launcher": "~2.1.1","karma-cli": "~1.0.1","karma-coverage-istanbul-reporter": "^1.3.3","karma-jasmine": "^1.1.1","karma-jasmine-html-reporter": "^0.2.2","protractor": "~5.1.2","ts-node": "~3.0.4","tslint": "~5.3.2","typescript": "2.4.2","webpack": "^3.10.0"
      }

此时,我仍然无法导入MatTableDataSource：

...node_modules/@angular/material/material"' has no exported member 'MatTableDataSource'.

…所以我增加了Material和CDK版本：

git diff package.json：

"dependencies": {
     "@angular/animations": "^5.2.0",-    "@angular/cdk": "^2.0.0-beta.12",+    "@angular/cdk": "^5.0.0-rc0",-    "@angular/material": "^2.0.0-beta.12",+    "@angular/material": "^5.0.0-rc0",.
.

现在我可以毫无问题地构建,但是当我的页面呈现时,我在控制台中看到了这一点：

Uncaught Error: Template parse errors:
'mat-card-title' is not a known element:
1. If 'mat-card-title' is an Angular component,then verify that it is part of this module.
2. If 'mat-card-title' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.

……现在我完全糊涂了.我在模板中使用的每个“未知”材料卡相关标签都存在上述错误之一.突然没有材料卡可供使用,我做错了什么？
