SyntaxError：意外的令牌导入 TypeORM 实体

因此，我正在使用 TypeORM，并且当我将 TypeScript 转换为 JavaScript 时遇到奇怪的错误。我收到以下错误：

(function (exports, require, module, __filename, __dirname) { import { Entity, PrimaryGeneratedColumn, ManyToOne, OneToMany, TreeChildren, TreeParent, JoinColumn, Column, Tree, TreeLevelColumn } from "typeorm";
                                                              ^^^^^^

My tsconfig.json:

        "lib": [

           "es6"

抛出错误的文件：

import { Entity, PrimaryGeneratedColumn, ManyToOne, OneToMany, TreeChildren, TreeParent, JoinColumn, Column, Tree, TreeLevelColumn } from "typeorm";
import { User } from "./User";
import { Debate } from "./Debate";


@Entity()
@Tree("closure-table")
export class Comment {

    @PrimaryGeneratedColumn("uuid")
    id: string;

    @Column()
    text: string;

    @ManyToOne(type => User)
    user: User;

    @ManyToOne(type => Debate, debate => debate.comments)
    debate: Debate;

    @TreeChildren()
    children: Comment[];

    @TreeParent()
    parent: Comment;
}

我尝试过的：

• 我尝试将我的node.js更新到最新版本（版本8.11.2）
• 我尝试以“es5”、“es6”和“es7”的各种组合更改 tsconfig.json 中的“lib”设置
• 我尝试将 tsconfig.json 的“目标”更改为上面项目符号点中列出的目标。
• 我尝试更改实体文件中的导入语句import (lib) from (module) to const (lib) require (module)";然而，这会导致更多问题并且效果不佳。

我一直在谷歌上广泛搜索这个问题，这让我摸不着头脑。任何和所有的帮助将不胜感激。

好吧，我简直就是个傻子。

因此，ormconfig.json 将您的实体指向 /src 文件夹中的 ts 文件。当您构建项目时，它应该指向您的实体所在的位置。我确实认为它在构建后试图引用 TS 文件很奇怪。
