Angular2 错误：从导出类返回的公共方法的类型已经或正在使用私有名称

Question

在最初使用非 CLI 版本的 Angular 2 构建应用程序的工作版本之后，我正在使用 Angular-CLI 构建一个 Angular 2 应用程序。令我惊讶的是，一些在我的代码中不是问题的代码非 CLI 应用程序版本一直是我的 Angular-CLI 版本的问题。综上所述，我已经解决了所有问题，除了我遇到的最后一个错误。

这是我收到的错误消息：

未捕获的错误：模块构建失败：错误： /Users/fdr/Documents/rds/rds/cli-rds/src/app/ui/generate-field.component.ts (340,48)：从导出类返回的公共方法的类型有或者是 使用私有名称“提示”。）

这是导致错误的问题文件：

interface ISuggestion
{

    word: string;

    match: string;

    value: string;
}

Answer 1

尝试在代码的最后部分添加“export interface ISuggestion”，以便将 ISuggestion 也导出。

Answer 2

尝试在您的方法之后添加 : any。我遇到了同样的问题，添加任何后就解决了。
