Question

当我尝试运行编译的打字稿代码时，出现语法错误：

\entity\Config.ts:1
(function (exports, require, module, __filename, __dirname) { import { Entity, PrimaryGeneratedColumn, Column, BaseEntity } from "typeorm";
                                                                     ^

SyntaxError: Unexpected token {

但是当我使用ts-node和nodemon代码运行打字稿代码时，运行得很好。

因此，我一直在进行一些日志记录，以找出问题出在哪里，而当我在TypeORM上点击createConnection()方法时，问题似乎就发生了。我是Typescript和TypeORM库的新手。

entity / config.ts

import { Entity, PrimaryGeneratedColumn, Column, BaseEntity } from "typeorm";

@Entity()
export class Config extends BaseEntity {
  @PrimaryGeneratedColumn()
  id: number;

  @Column()
  app: String;

  @Column()
  endpoint: String;

  @Column()
  token: String;
}

server.ts

import { createConnection } from "typeorm";

// Database connected
createConnection()
  .then(() => {
    console.log("Test");
  })
  .catch(err => {
    console.log(err);
  });

index.ts

require("reflect-metadata");
require("dotenv/config");
require("./server");

package.json相关性

    "scripts": {
    "dev:server": "ts-node src",
    "dev": "nodemon -e ts -w src -x npm run dev:server",
    "build:server": "tsc",
    "start:server": "node build/index.js",
    "start": "npm run build:server && npm run start:server"

因此TypeORM Slack的成员（由uladzimir回答此问题时）解决了该问题。问题出在我的ormconfig文件中。

问题：

"entities": ["src/database/entity/**/*.ts", "build/database/entity/**/*.js"],
  "migrations": [
    "src/database/migration/**/*.ts",
    "build/database/migration/**/*.js"
  ],
  "subscribers": [
    "src/database/subscriber/**/*.ts",
    "build/database/subscriber/**/*.js"
  ],
  "cli": {
    "entitiesDir": "src/entity",
    "migrationsDir": "src/migration",
    "subscribersDir": "src/subscriber"
  }

解决方案：

"entities": ["build/database/entity/**/*.js"],
  "migrations": ["build/database/migration/**/*.js"],
  "subscribers": ["build/database/subscriber/**/*.js"],
  "cli": {
    "entitiesDir": "src/entity",
    "migrationsDir": "src/migration",
    "subscribersDir": "src/subscriber"
  }

出于某种原因，我认为我必须添加*ts文件用于测试/开发目的，但事实并非如此，这是导致问题的原因。我不确定为什么会导致此问题，但是如果发现，我会将其作为对此答案的评论。

感谢大家在此问题上的帮助。

Answer 2

我设法通过删除ormconfig.json文件并在createConnection函数中传递数据库配置来解决此问题。

示例：

import { User } from './entity'
// import every other entity you have
// .......

await createConnection({
        type: 'sqlite',
        database: 'database.sqlite',
        synchronize: true,
        logging: true,
        entities: [
            User // pass your entities in here
        ]
    })

如果您使用的是 TypeOrm，则可以将其用作配置

  entities: [__dirname + '/models/**/*.entity.{ts,js}'],
  migrations: [__dirname + '/migrations/**/*.{ts,js}'],
  subscribers: [__dirname + '/subscriber/**/*.{ts,js}'],

添加 __dirname 可以正确解析模块，具体取决于您是在 dev（解析为 ts 版本）还是 prod（解析为 js 版本）中运行它
