angular-material - 安装 Angular Material 时的警告

Question

我安装了 Angular Material 并注意到控制台上有几个警告。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。看来您使用的是早期的 Angular 版本。

对于 Angular 5，您可以在 5.x.x 版本中使用 @angular/material 通过更新 package.json 如下:

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