在执行"npm安装“之后，安装了太多的npm模块

Question

我的package.json

{
  "name": "thumbnaillist-gulp",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "browserify": "^12.0.1",
    "gulp": "^3.9.0",
    "gulp-concat": "^2.6.0",
    "gulp-react": "^3.1.0",
    "gulp-util": "^3.0.7",
    "react": "^0.13.3",
    "react-script-loader": "0.0.1",
    "reactify": "^1.1.1",
    "vinyl-source-stream": "^1.1.0",
    "watchify": "^3.6.1"
  }
}

奇怪的是，在我执行"npm“之后，除了依赖项字段中列出的模块之外，还安装了其他模块，例如

有什么线索吗？我的NPM坏了吗？或者我没有以正确的方式写package.json。

Answer 1

不，没有什么问题，NPM现在将所有依赖项安装到根模块文件夹，除非存在版本冲突。您所看到的所有其他模块都是您安装的模块的依赖项。

来自NPM 3.0.0 release notes

现在，您的依赖项将以最大的平面安装。在可能的范围内，您的所有依赖项、它们的依赖项以及它们的依赖项都将安装在项目的node_modules文件夹中，而不需要嵌套。只有当两个(或更多)模块有相互冲突的依赖时，您才会看到嵌套在另一个下面的模块。

Answer 2

我希望Alexander‘’Mara的回答对你有帮助，如果你还想要的话，或者那些想要像旧版本那样使用依赖关系的人。

您可以使用

npm安装--遗留捆绑

如果你总想用

npm集遗留捆绑=真

并且可以像往常一样运行。

npm安装
