安装Angular材料时发出警告

Question

我安装了Angular Material并在控制台上发现了几个警告.我有不兼容或缺少的库吗？

您在 6.1.0 中使用@angular/material。此版本旨在与 Angular 6 配合使用。看来您正在使用早期的 Angular 版本。

对于 Angular 5，您可以通过更新 package.json 在 5.xx 版本中使用 @angular/material，如下所示：

"dependencies": {
    ...
    "@angular/cdk": "^5.2.5",
    "@angular/material": "^5.2.5",
    ...
 },
