NestJS工作区构建后无法找到编译源文件问题求助

我将NestJS项目目录重命名为server，并把docker-compose.yml、tsconfig.json和根目录的package.json移到了该文件夹外部。根目录的package.json中配置了工作区，用于访问不同命名空间。

执行npm run start启动Docker后，根目录（server文件夹外）生成了dist文件夹，结构如下：

但server内的项目无法运行，抛出错误：

Error: Cannot find module '/opt/dist/main'

Docker启动命令：

npm run start

根目录package.json内容 #

根目录tsconfig.json内容（与docker-compose.yml同级） #

        "target": "ES2023",
        "sourceMap": true,
        "outDir": "./dist",
        "baseUrl": "./",
        "incremental": true,
        "skipLibCheck": true,

}

server文件夹内package.json内容 #

server文件夹内tsconfig.json内容 #

{
    "compilerOptions": {
        "types": ["node"],
        "module": "commonjs",
        "declaration": true,
        "removeComments": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "allowSyntheticDefaultImports": true,
        "target": "ES2023",
        "sourceMap": true,
        "outDir": "./dist",

        "noFallthroughCasesInSwitch": false,
    }
}

1. 修正server目录package.json的main字段 #

当前server目录的package.json中main字段错误指向.eslintrc.js，需改为编译后的入口文件路径：

{
  // ...其他配置项
  "main": "dist/main.js",
  // ...其他配置项
}

2. 调整server目录tsconfig.json的输出路径 #

server目录的tsconfig目前将产物输出到自身./dist，与根目录tsconfig的输出路径冲突。修改为输出到根目录dist下的对应子目录，符合npm工作区结构：

{
  "compilerOptions": {
    // ...其他编译配置
    "outDir": "../dist/auction-server",
    // ...其他编译配置
  }
}

3. 修正根目录工作区配置与启动脚本 #

根目录package.json的工作区配置仍指向旧目录名auction-server，需改为实际目录名server，同时更新启动脚本：

{
  "workspaces": [
    "auction-client",
    "server", // 替换为实际目录名
    "shared"
  ],
  "scripts": {
    // ...其他脚本
    "server:dev": "wait-on tcp:6379 && npm run start:dev --workspace=server",
    // ...其他脚本
  }
}

4. 明确Docker容器内的启动命令 #

修改docker-compose.yml的command字段，直接指定工作区启动命令，避免路径混淆：

services:
  app:
    # ...其他配置
    command: npm run start:dev --workspace=server
    # ...其他配置

5. 清理旧编译产物 #

删除根目录和server目录下的dist文件夹，避免缓存干扰，重新执行启动命令。
