我正在尝试按照此guide构建一个Angular 4 Universal App。但是，当我调用ngc生成NgModuleNgFactory时失败了，我收到了这个错误：

看起来编译器正在尝试处理不存在的文件/home/poi/Projects/solomon/src/app/module/archive/~@angular/material/theming，我在guide之后的scss中导入了~@angular/material/theming。
那么如何谈论文件编译器的位置？ ：（
仅供参考，@angular/material的版本为2.0.0-beta.5，而@angular/compiler和@angular/compiler-cli均为4.1.2。
