node.js - nodemon 无法使用express v4 启动nodejs 应用程序

Question

必须有一些简单的解决方案来解决这个问题。我使用 Webstorm for Express js + Node js 创建了一个新项目。然后我使用npm install -g nodemon安装了nodemon，一切都很好。但是当我尝试使用 nodemon app.js 启动我的应用程序时，它仅显示

sany2k8@sany2k8-Aspire-4752:/var/projects/ENStack$ nodemon app.js

[nodemon] 1.9.2

[nodemon] to restart at any time, enter rs [nodemon] watching: .

[nodemon] starting node app.js

[nodemon] clean exit - waiting for changes before restart

package.json

{
  "name": "ENStack",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www"
  },
  "dependencies": {
    "body-parser": "~1.13.2",
    "cookie-parser": "~1.3.5",
    "debug": "~2.2.0",
    "express": "~4.13.1",
    "jade": "~1.11.0",
    "morgan": "~1.6.1",
    "serve-favicon": "~2.3.0"
  }
}

编辑:当我尝试使用npm start时，它显示了一堆错误

sany2k8@sany2k8-Aspire-4752:/var/projects/ENStack$ npm start

ENStack@0.0.0 start /var/projects/ENStack node ./bin/www

端口 3000 已被使用

Answer 1

我们需要在 json 文件中添加 start 和 nodemon ./bin/www ，并且使用以下命令运行您的项目:nodemon app

{
  "name": "ENStack",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "nodemon ./bin/www"
  },
  "dependencies": {
    "body-parser": "~1.13.2",
    "cookie-parser": "~1.3.5",
    "debug": "~2.2.0",
    "express": "~4.13.1",
    "jade": "~1.11.0",
    "morgan": "~1.6.1",
    "serve-favicon": "~2.3.0"
  }
}
