typescript-uncaught referenceError：未定义require

Question

Visual Studio 2015更新3。 我收到了错误：

import { Category } from "./Enums"; at runtime.

在：

export enum Category { Biography, Poetry, Fiction, History, Children }

我真的不明白为什么我会收到这个错误（我对Typescript很新）

enums.ts：

import { Category } from './enums';
export interface Book {
    id: number;
    title: string;
    author: string;
    available: boolean;
    category: Category;
    pages?: number;
    markDamaged?: DamageLogger;
}

interface.ts：

import { Category } from './enums';
import { Book, DamageLogger, Author, Librarian } from './interfaces';
import { UniversityLibrarian } from './classes';

function GetAllBooks(): Book[] {

    let books = [
        { id: 1, title: 'Ulysses', author: 'James Joyce', available: true, category: Category.Fiction },
        { id: 2, title: 'A Farewell to Arms', author: 'Ernest Hemingway', available: false, category: Category.Fiction },
        { id: 3, title: 'I Know Why the Caged Bird Sings', author: 'Maya Angelou', available: true, category: Category.Poetry },
        { id: 4, title: 'Moby Dick', author: 'Herman Melville', available: true, category: Category.Fiction }
    ];

    return books

app.ts：

def getRankingsFromGoogle(keyword, website, page = 1, count = 1): 

   if count is 5: 
   print "NOT ON PAGE 5" 

Answer 1

您需要安装节点

的类型

npm i -D @types/node

require definition is in there

Answer 2

我使用＆＃34; outFile＆＃34;解决了这个错误。在tsconfig.json中。 如果我们使用＆＃34; outFile＆＃34;我们不应该使用＆＃34; module＆＃34;：＆＃34; commonjs＆＃34;，我们应该只使用＆＃34; amd＆＃34;和＆＃34;系统＆＃34;
