devDependencies“模块找不到”错误

Question

我分开devDependencies和dependencies

{ 
    "name": "contenttype", 
    "version": "1.0.0", 
    "description": "", 
    "main": "index.js", 
    "scripts": { 
    "test": "echo \"Error: no test specified\" && exit 1" 
    }, 
    "author": "", 
    "license": "ISC", 
    "dependencies": { 
    "react": "^15.3.2", 
    "react-dom": "^15.3.2" 
    }, 
    "scripts": { 
    "dev": "webpack-dev-server --content-base src --inline --hot" 
    }, 
    "devDependencies": { 
    "babel-core": "^6.18.2", 
    "babel-loader": "^6.2.7", 
    "babel-preset-es2015": "^6.18.0", 
    "babel-preset-react": "^6.16.0", 
    "webpack": "^1.13.3" 
    } 
} 

之间我的依赖性正如你可以看到我有一个npm脚本，但是当我运行npm run dev，我得到的错误

webpack module not found 

这是为什么？ webpack模块位于我的devDependencies中，为什么它不被识别？

Answer 1

npm install webpack-dev-server --save-dev
