【问题描述】：
我是 Angular2 的新手。所以我正在一个项目中使用角材料。但是，我有那些：
“没有导出的成员 MD_XXX_DIRECTIVES”错误（例如：MD_SIDENAV_DIRECTIVES,MD_LIST_DIRECTIVES）。
这些是 package.json 依赖项：
"dependencies": {
"@angular/common": "2.0.0-rc.4",
"@angular/compiler": "2.0.0-rc.4",
"@angular/core": "2.0.0-rc.4",
"@angular/forms": "0.2.0",
"@angular/http": "2.0.0-rc.4",
"@angular/platform-browser": "2.0.0-rc.4",
"@angular/platform-browser-dynamic": "2.0.0-rc.4",
"@angular/router": "3.0.0-beta.2",

"@angular2-material/sidenav": "^2.0.0-alpha.5-2",
"@angular2-material/toolbar": "^2.0.0-alpha.5-2"}
感谢您的帮助。
【问题讨论】：
-
你能告诉我们你是如何导入材料设计的吗？
-
import {MD_SIDENAV_DIRECTIVES} from "@angular2-material/sidenav"; -
因为您在材料包上有
^指示符，我想知道它是否没有拉下您指定的较新版本，较新版本移至模块概念保留与 Angular 一致。能不能把材料包上的^去掉，然后去掉包重新安装看看能不能用？ -
好的，我现在试试

安装时出现错误：
