我正在使用我购买的 akveo 后端捆绑包，虽然在开发模式下一切似乎都运行良好，但从生产开始给我以下错误，但我对 nestjs 本身还是新手。有人知道这是怎么回事吗？

node_modules/@nestjs/core/adapters/http-adapter.d.ts:5:31 - error TS2420: Class 'AbstractHttpAdapter<TServer, TRequest, TResponse>' incorrectly implements interface 'HttpServer<TRequest, TResponse>'.
    Property 'status' is missing in type 'AbstractHttpAdapter<TServer, TRequest, TResponse>' but required in type 'HttpServer<TRequest, TResponse>'.

5 export declare abstract class AbstractHttpAdapter<TServer = any, TRequest = any, TResponse = any> implements HttpServer<TRequest, TResponse> {

    Found 5 errors.

我正在使用tsc -p tsconfig.build.json 命令用tsconfig.build.json 构建它：

{
    "extends": "./tsconfig.json",
    "exclude": ["node_modules", "test", "**/*spec.ts"]
}

和tsconfig.json:

{
    "compilerOptions": {
        "module": "commonjs",
        "declaration": true,
        "removeComments": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "target": "es6",
        "sourceMap": true,
        "outDir": "./dist",
        "baseUrl": "./"
    },
    "exclude": ["node_modules"]
}

我希望这个配置应该将 typescript 代码编译为 javascript，然后我将使用 node dist/main.js 命令运行。它实际上是这样做的。但我担心打字稿编译器错误。

【问题讨论】：

请将您的错误粘贴到 StackOverflow 中。图片难以阅读，并阻止其他人提供帮助。你用的是什么启动命令？你是如何构建你的项目的？您如何测试部署？您要部署到哪里（如果您当前正在部署服务器）？
抱歉，我以后会记住这一点。我已经编辑了问题。

【解决方案1】：

不确定没有代码，但曾在嵌套核心包中遇到过类似的不匹配。查看package.json 并确保所有@nest 软件包具有相同的版本，因为有时即使不是主要版本，它们也会有“重大”更改。

举个抽象的例子，在构建生产环境时，类似的事情给了我与core 相关的错误：

   "@nestjs/common": "6.6.0",  // notice the core/common does not match, it should be bumped
   "@nestjs/core": "6.6.2",

【讨论】：

事实证明，这确实是问题所在。尽管现在我使用nestjs 无法解决猫鼬@InjectModel 依赖项。但这是另一个问题。
