Question

我使用Angular select组件从Internet下载了一个Angular项目。

以下是原始示例：

https://material.angular.io/components/select/overview#resetting-the-select-value

他们在以下链接上有一个演示：

https://stackblitz.com/angular/qodvbqymxae

我将该演示下载到我的计算机上，但在执行时：

$ ng serve

我收到错误：

ERROR in Error: Tried to find bootstrap code, but could not. Specify either statically analyzable bootstrap code or pass in an entryModule to the plugins options.
    at Object.resolveEntryModuleFromMain (D:\_System\Hatuey\Desktop\angular-material-select\node_modules\@ngtools\webpack\src\entry_resolver.js:131:11)

    at process._tickCallback (internal/process/next_tick.js:109:7)

正如您在以下完整输出中看到的那样：

在README.md提供的stackblitz.com文件中（导出时），他们说：

This project was generated with Angular CLI version 1.2.1.

在我的本地计算机上，我得到以下内容：

$ ng version
...
Angular CLI: 1.5.4
Node: 6.11.2
OS: win32 x64
Angular: 5.1.3
...

如果您想自己尝试，可以这样做：

$ mkdir angular-material-select
$ cd angular-material-select
$ git clone git@github.com:napolev/angular-material-select.git .
$ npm install
$ ng serve

如何让这个演示项目有效？

Answer 1

从AppModule将main.ts提取到自己的文件app.module.ts
将DemoMaterialModule中的main.ts提取到自己的文件中
将DemoMaterialModule添加到AppModule＆＃39; imports列表

无法构建此Angular项目
