我有一个 NodeJs 项目，我使用 nodemon 运行它，
我希望在 Debug模式下运行它来执行开发任务，但我无法这样做。
我发现我需要将正确的配置添加到 .vscode 文件夹下的 launch.json 文件中，
我有一个 app.js 文件，它是主应用程序文件。
该应用程序在 Node 版本 4.6.2 和端口 8080 上运行。
通常情况下，我使用 npm run dev 命令运行应用程序。
以下是我的 launch.json 文件 -

"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "launch",
"name": "MyApp",
"program": "${workspaceFolder}/app.js",
"runtimeVersion": "4.6.2",
"protocol": "legacy",
"port": 8080
//"runtimeExecutable": "/home/user/.nvm/versions/node/v4.6.2/bin/node"
},
{
"type": "node",
"request": "launch",
"name": "nodemon",
"runtimeExecutable": "nodemon",
"program": "${workspaceRoot}/app.js",
"restart": true,
"console": "integratedTerminal",

},
{
"type": "node",
"request": "launch",
"name": "DEBUG",
"runtimeExecutable": "nodemon",
"program": "${workspaceFolder}/app.js",
"restart": true,
"console": "integratedTerminal",
"internalConsoleOptions": "neverOpen",
"runtimeVersion": "4.6.2",
"protocol": "legacy",
"port": 8080
}
]
}
package.json 如下 -

当我运行 DEBUG 和 nodemon 配置时，应用程序将启动，
但代码并没有在我放在 app.js 文件上的断点处暂停。

package.json 中需要进行哪些更改，或者启动配置 - launch.json 中需要进行哪些更正，才能帮助我在 VSCode 中针对我的用例调试应用程序？
最佳答案
将 package.json 更改为
"scripts": {
"dev": "node app.js",
"debug": "nodemon --inspect app.js"
}
--inspect is for versions >= 6.3. --legacy or --auto for older versions
并将 launch.json 发送到:
"version": "0.2.0",
"configurations": [
{
"type": "node",
"request": "attach",
"name": "Node: Nodemon",
"processId": "${command:PickProcess}",
"restart": true,
"protocol": "inspector"
}
]
重启标志是这里的关键。
通过新的调试脚本启动应用程序
npm run debug
- 在“调试” View 中，选择 Node :Nodemon 配置并按“播放” 或F5
- 选择上面启动的流程
