Angular 4 与 Material

Question

我正在尝试使用 Angular4 实现“Angular-Material”。我从 Angular Material [angular.material.io][1] 的官方网站进行了所有设置

[1]: https://material.angular.io/guide/getting-started但是当尝试通过 npm start 运行项目时，出现以下错误:

node_modules/@angular/material/typings/button/button.d.ts(40,22): error TS2420: Class 'MdButton' incorrectly implements interface 'CanDisable'. Property 'disabled' is private in type 'MdButton' but not in type 'CanDisable'. node_modules/@angular/material/typings/button/button.d.ts(40,39): error TS2507: Type '(new (...args: any[]) => CanDisable) & typeof MdButtonBase' is not a constructor function type. node_modules/@angular/material/typings/checkbox/checkbox.d.ts(43,22): error TS2420: Class 'MdCheckbox' incorrectly implements interface 'CanDisable'.

有人，请帮我解决上面的问题。

仔细检查您的 package.json 依赖项和 devDependencies 文件并找到您的 typescript 安装。确保它是 2.2.0 或更高版本。

"typescript": "~2.2.0"

如果你做了改变，一定要运行

$ npm update -D

如果你全局安装了它并且你的 package.json 文件中没有 typescript 行，运行

$ npm install -g typescript@2.2.0
