docker-compose用于将VS Code中的node.js调试器附加到WSL docker中的节点进程

我确实在尽力而为，但我不知道我在做什么错。

我有一个可以在Win10和Linux容器上启动和调试的现有项目。但是我希望能够将调试器附加到Win10上的WSL容器中，现在我真的失去了耐心。

因此，我在Win10和WSL2上安装了VS Code。我有Remote-WSL扩展（也有Remote-Containers，但也不能使它正常工作，因此暂时不进行扩展）。如果可能的话，我宁愿保持Dockerfile不变。

当我尝试通过运行“ Docker：附加到节点”配置附加到节点调试器时，出现以下错误：

Error processing attach: Error: Could not connect to debug target at http://localhost:9229: Promise was canceled

这是我的档案...

            "remoteRoot": "/src/app",
            "protocol": "inspector"
        }
    ]
}

当我将以下内容添加到docker.compose.yml中时

command: sh -c "npm run start:debug:docker"

我明白了 docker-compose up

web_1  | npm ERR! missing script: start:debug:docker

我尝试谷歌搜索以获取其他信息，并且该想法可能是在调试模式下运行节点，但显然无法使其正常工作。任何帮助表示赞赏！

是这样的：

/gulpfile.js

'use strict';
let gulp = require('gulp');
let nodemon = require('gulp-nodemon');

let started = !1;
let paths = {
    js: [
        '**/*.js',
        '!node_modules'
    ]
};

gulp.task('prod', (e) => {
    nodemon({
        script: './app/app.js',
        ext: 'js',
        watch: paths.js,
        ignore: ['./app/node_modules/**']
    }).on('start', () => {
        started || (started = !0, e());
    });
});

当我将此行添加到nodemon选项以启用debug over inspect时：
