Angular 错误：找不到模块'@角/材料

错误

找不到模块“@angular/material”

app.module.ts

import { MaterialModule } from '@angular/material';

链接：

我尝试的解决方案

npm更新

它不起作用

ng——版本

• 运行npm命令物料模块后，是否有人建议我停止工作

我已经做了工作演示

所有代码都正常工作

• 任何建议都欢迎

安装材料时出错

以下是材料2：

它说：从2.beta-11开始，角度材料现在需要角度4.4.3或更高

如果您想要材质的最新版本，则必须升级到angular 5+

---

如果您想坚持使用4.3.2版，那么最后一次可以安装的版本是2.0.0-beta10（我不建议这样）

查看错误，您会发现一些软件包需要angular v.4.4。因此，我建议您将所有@angular软件包更新为v.4.4.4

按照以下步骤操作：

1.）卸下节点单元模块

2.

npm缓存清理

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

---

4.

npm安装

看起来物料模块没有安装。当您点击npm install命令时，您是否在控制台中遇到任何错误？正如您所看到的，当我运行npm cmd时，github代码正在工作，然后出现错误，请尝试通过“npm uinstall--save@angular/material”卸载，然后再次安装“npm install--save@angular/material”我在安装materialI时出现更新错误。我已克隆了您的回购协议并成功地安装了所有npm。我正在使用NPM5.4.2。正在尝试更新您的npm并在新位置点击npm安装。我已使用cmd>npm update-D&&npm update-S进行了更新
