sequelize当使用glob配置与‘When’编译器(使用NestJS)时，无法解析模型模块

Question

我正在建立sequelize-typescript，然后添加模型：

    import appRoot from 'app-root-path'

    connection = new Sequelize({... connection details})
    const appGlobPattern = join(appRoot.toString(), 'src/**/entities/*.entity.ts')
    // appGlobPattern = absolute path to the root of the project (i.e. C:/Users/user/my-project/)
    this.connection.addModels([appGlobPattern])

尝试在sequelize-service (https://github.com/RobinBuschmann/sequelize-typescript/blob/1c34e87c968b1c8333ef6467c2dd44e069e06fa8/src/sequelize/sequelize/sequelize-service.ts#L57)中执行sequelize-service行时引发错误

引发一个错误，因为文件解析程序无法解析该文件(该文件存在)：

'C:\Users\user\my-project\src\entities\my-model.entity‘错误:找不到模块

全栈轨道

在NestJS默认使用的tsc编译器中，似乎有可能出现这种情况。或者模块加载器对绝对文件路径不友好。

更多详细信息：

“版本”："5.21.2"

• sequelize-typescript：“版本”："1.0.0"

• typescript“版本”："3.7.2"

这些是我的tsconfig设置：

{
  "compilerOptions": {
    "module": "CommonJS",
    "moduleResolution": "node",
    "declaration": true,
    "removeComments": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "esModuleInterop": true,
    "target": "ES6",
    "sourceMap": true,
    "outDir": "./dist",
    "baseUrl": "./",
    "incremental": true,
    "paths": {
      "express": ["src/multi-tenancy/types/*"]
    }
  },
  "exclude": ["node_modules", "dist"]
}

您不应该将src作为文件路径的一部分，因为一旦您将代码从类型记录编译为JavaScript，您的代码现在就位于dist中，而src文件夹在上下文中丢失了。您还应该将.ts更改为.js，因为这将在运行时解析文件。另一种选择是使用类似于join(__dirname, '{dist,src}/**/entities/*.entity.{js,ts}')的glob，这样您就可以在不改变src和dist之间代码的情况下查看两者。

注意：join来自path模块
