Angular 安装角材料后，节点模块中出现多个生成/编译错误--

我的项目在8号楼。 我在上面安装了有棱角的材料。现在，当我尝试启动我的应用程序时，我遇到了以下一系列构建错误--

我的app.module.ts导入部分中有这一行--

我查阅了更多的链接，并根据它们安装了rxjs compat，@angular/cdk，正如您在上面看到的。但错误依然存在

---

我不想用激进的方法来解决这个问题。解决上述问题并使其重新运行的最短最聪明的方法是什么？这里需要哪些更具体的软件包？我是否应该在app.module行中包含更多必要的导入？它是什么。寻找快速解决方案。

您使用的材料版本太旧，很可能导致问题。最新的稳定版本是

8.2.3

-尝试更新它。你确定你安装了

@angular/material

你的

软件包。json

则相反。

import{Http}from'@angular/Http'

认为你一直在使用angular的旧版本，而现在刚刚更新到angular8？@Eldar yep--在我的软件包中看到这一点。json-->“@angular/material”：“^2.0.0-beta.2“它就在那里，hi@tftd让我进行版本更新，然后，您使用的材料版本太旧，这很可能是导致问题的原因。最新的稳定版本是
