我正在尝试使用.NET Core和Angular在dev容器内运行项目。

.NET Core项目在此容器中运行没有问题，但是Angular项目出现了一些问题。

当我在vscode中手动启动终端时，转到Angular项目目录，然后运行npm run ng serve-一切正常。

但是，我试图在task.json中定义任务，这使我可以运行相同的命令-存在错误。

这是我的Dockerfile specyfing开发容器：

这是我的devcontainer.json

{
    "name": "Docker in Docker Compose","dockerComposeFile": "docker-compose.yml","appPort": [
        5000,5001,5005,4200
    ],"service": "docker-in-docker","workspaceFolder": "/workspace","settings": {

    ]
}

和launch.json

{
    "version": "2.0.0","tasks": [
        {
            "label": "build","command": "dotnet","type": "process","args": [
                "build","${workspaceFolder}/TaskManager/TaskManager.sln","/property:GenerateFullPaths=true","/consoleloggerparameters:NoSummary"
            ],"problemMatcher": "$msCompile"
        },{
            "type": "npm","label": "angular testing","script": "start"        
        }
    ]
}

启动带有标签“ build”的任务成功。 标签为“角度测试”的启动任务会导致：

> Executing task: npm run start <
/bin/bash: npm: command not found
The terminal process terminated with exit code: 127

我也尝试过测试任务定义：

            "type": "shell","command": "which","args": [
                "npm"
            ]
}

此结果与

> Executing task: which npm <
The terminal process terminated with exit code: 1

在vs代码中运行终端“ bash”并测试npm版本：

root@43f83c4b3ce5:/workspace# npm version
{
  npm: '6.12.0',...
}

看起来不错。

如何定义在此dev容器内成功运行npm命令的任务？
