错误

找不到模块'@angular/material

app.module.ts

import  MaterialModule  from '@angular/material';

链接：https://material.angular.io/guide/getting-started

 npm install --save @angular/material @angular/cdk

我尝试过的解决方案

npm 更新

它不起作用。

ng --version

@angular/cli: 1.2.1
node: 8.3.0
os: win32 x64
@angular/animation: 4.0.0-beta.8
@angular/animations: error
@angular/cdk: error
@angular/common: 4.3.2
@angular/compiler: 4.3.2
@angular/core: 4.3.2
@angular/forms: 4.3.2
@angular/http: 4.3.2
@angular/material: error
@angular/platform-browser: 4.3.2
@angular/platform-browser-dynamic: 4.3.2
@angular/router: 4.3.2
@angular/cli: 1.2.1
@angular/compiler-cli: 4.4.3
@angular/language-service: 4.3.2

在运行 npm 命令材料模块停止工作后，任何人都可以建议我。

我已经做了工作演示https://github.com/afeef1915/Angular2-Symfony3-Demo

所有代码都运行良好。

欢迎提出任何建议。

【问题讨论】：

好像没有安装材料模块。当您点击 npm install 命令时，您是否在控制台中遇到任何错误？你可以看到 github 代码在我运行 npm cmd 后立即运行，然后出现错误尝试通过“npm uinstall --save @angular/material”卸载并再次安装“npm install --save @angular/material” 安装材料时出现更新错误我已经克隆了你的 repo 并成功安装了所有 npm。我正在使用 npm 5.4.2。尝试更新您的 npm 并在新位置点击 npm install。 【参考方案1】：

查看错误，您会看到某些包需要 angular v.4.4.4。所以我建议你将所有 @angular-packages 更新到 v.4.4.4。

按照以下步骤操作：

1.) 移除 node_modules

2.) npm cache clean

3.) 打开 packages.json 并将所有 @angular-packages 的版本设置为 "^4.4.4"

4.) npm install

【讨论】：

我已经用 cmd 更新了>npm update -D && npm update -S【参考方案2】：

这里是材料2的changelog：

它说：Angular Material 现在需要 Angular 4.4.3 或更高版本，因为 2.beta-11

如果你想要最新版本的材料，你必须升级到 Angular 5+

如果您想坚持使用 4.3.2 版本，您可以安装的最后一个版本是 2.0.0-beta10（我不建议这样做）
