为 angular 添加 angular material 时出错 6

Question

我真的是angular的新手，我正在学习angular 6 但我无法添加入门页面 via

中所说的组件

ng add component heroes

发生错误，错误是：

Schematic input does not validate against the Schema: {"dryRun":false,"inlineStyle":false,"
inlineTemplate":false,"changeDetection":"Default","styleext":"css","spec":true,"flat":false
,"skipImport":false,"export":false}
Errors:

  Data path "" should NOT have additional properties(dryRun).

当我用谷歌搜索时，有人说可以通过添加 angular material 来修复它，所以我开始安装 angular material，但是我的应用程序错误这是控制台日志：

请大家帮帮我

Answer 1

您似乎在尝试生成一个新组件，使用添加，您可以将库添加到您的依赖项-(package.json)。尝试
"ng generate component [component name]" (https://github.com/angular/angular-cli/wiki/generate-component).

你安装了angular/cli吗？要使用 ng 生成组件，您需要 angular/cli。 https://cli.angular.io/

无论如何你都可以观看这个 "Angular Material Introduction & Setup" 视频 https://www.youtube.com/watch?v=u679SQsfRVM

Answer 2

你用错了，但首先如果你只是用 angular 学习，没有必要使用 angular material 这个想法是误导。

吴加

Another new CLI command ng add <package> makes adding new capabilities to your project easy. ng add will use your package manager to download new dependencies and invoke an installation script (implemented as a schematic) which can update your project with configuration changes, add additional dependencies (e.g. polyfills), or scaffold package-specific initialization code.

ng add命令只用于依赖管理，勾选this。

如果您尝试生成组件，请遵循以下步骤：

ng generate component my-new-component
ng g component my-new-component # using the alias

在潜水前学习 angular-cli 的基础知识，或者至少完成 angular.io.

Answer 3

Data path "" should NOT have additional properties(dryRun).

此错误不是 material 错误。

这意味着在您的 angular.json 文件中您将 "dryRun" 作为属性，这是不受支持的。看样子是
"dryRun" 属性允许您在不实际编辑文件的情况下查看执行 ng g 时会发生什么。

例如：ng g c ops-components/dividers --project ops-lib --dryRun

删除 dryRun 属性.
