Question

我真的很想使用有棱角的材料，应该不会这么难。我安装了这个包，当我尝试使用 matInput 时，我在构建时出错。如果发布 package.json 会有所帮助，请告诉我。

目标入口点“@angular/material/input”中的错误缺少依赖项：

@angular/core
@angular/forms
rxjs

我在 package.json 中没有看到 @angular/material。
您是否在使用 MatInput 的模块的导入中包含 FormsModule（或其他可能的依赖项）？
如果没有任何效果，请删除 node_modules 文件夹并再次运行 npm install。
