Nest 不使用 ts-transformer-keys

如何解决Nest 不使用 ts-transformer-keys

我正在尝试在我的 Nest 应用程序中使用 ts-transformation-keys。

我使用此 repository 中的模板启动了一个新应用程序，并且我的机器运行的是 Windows 10。

如 ts-transformation-keys 文档中所述，我在 tsconfig.json 文件中添加了以下配置：

{
  "compilerOptions": {
    "module": "commonjs","declaration": false,"removeComments": true,"emitDecoratorMetadata": true,"experimentalDecorators": true,"esModuleInterop": true,"allowSyntheticDefaultImports": true,"target": "ES2017","sourceMap": true,"outDir": "./dist","baseUrl": "./","incremental": true,"plugins": [
      { "transform": "ts-transformer-keys/transformer" },]
  },"exclude": [
    "node_modules","dist","graphql","onboard"
  ]
}

这是我的 package.json 文件：

问题来了：

我已经运行了这些脚本：

npm i -g @nestjs/cli
npm install
npm build
npm start:debug

所有这些都运行良好...但是当我尝试使用 ts-transformation-keys 时它不起作用。

我在 src/app.module.ts 中添加了一小段代码：

class myTestClass
{
  id : string;
  name : string;
}

let test = keys<myTestClass>()

然后我得到这个错误：

TypeError: ts_transformer_keys_1.keys is not a function
    at Object.<anonymous> (C:\Repos\EDM\backend\dist\app.module.js:26:34)
    at Module._compile (internal/modules/cjs/loader.js:1063:30)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1092:10)
    at Module.load (internal/modules/cjs/loader.js:928:32)

    at Module._compile (internal/modules/cjs/loader.js:1063:30)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1092:10)

它正在生成此 javascript 代码：

[...]
const ts_transformer_keys_1 = require("ts-transformer-keys");
class myTestClass {
}
let test = ts_transformer_keys_1.keys();
[...]

有人知道我的配置有什么问题吗？

我已经尝试使用不同版本的 ts-transformation-keys，但看起来 Nest 没有加载 tsconfig.json 文件中描述的自定义转换。
