【问题描述】：

我有一个 GraphQL 和 Apollo 服务器 https://github.com/AdhamAH/Film-and-actors-list/tree/main/server

在运行tsc -p . 然后node dist/index.js 之后，我从src 文件夹中的TS 文件中收到错误，如下所示

Film-and-actors-list\server\src\entities\Films.ts:1

import {Field, ObjectType} from "type-graphql";
^^^^^^

SyntaxError: Cannot use import statement outside a module

在没有运气的情况下搜索了几个小时后，我想到了删除 src 文件夹，当我运行 node dist/index.js 时，服务器启动时没有错误

我尝试更改 tsconfig.jsonoptions 但没有成功

我的tsconfig

{
  "compilerOptions": {
    "target": "es2017",
    "module": "commonjs",
    "lib": ["dom", "es6", "es2017", "esnext"],
    "skipLibCheck": true,
    "sourceMap": true,
    "outDir": "./dist",
    "moduleResolution": "node",

    "experimentalDecorators": true,
    "resolveJsonModule": true,
    "baseUrl": "."
  },
  "exclude": ["node_modules"],
  "include": ["./src/**/*.ts"]
}

还有我的package.json：

【问题讨论】：

标签： node.js typescript typeorm

【解决方案1】：

我想通了

问题是我有一个文件ormconfig.json 有以下内容

{
  "type": "sqlite",
  "database": "./db.sqlite3",
  "entities": ["./src/entities/*.ts"],
  "synchronize": true
}

所以看起来当我启动服务器时它正在从 entities 文件夹加载 TS 文件

我做了什么，我像这样将这个配置添加到index.ts

const connection = await createConnection({
      "type": "sqlite",
      "database": "./db.sqlite3",
      "entities": [User, Films],
      "synchronize": true
  })

通过这个我导入了实体并解决了问题

【讨论】：

我刚刚将 "entities": ["./src/entities/*.ts"], 从 ormconfig.json 更改为 "entities": ["./dist/entities/*.js"], ，它工作正常。
