打开命令提示符并进入项目目录（您可以右键单击解决scheme资源pipe理器中的项目，然后Open command prompt from here...select“ Open command prompt from here... ）。

键入npm init并在提示时填写字段（或Enter以采用默认值）。 输出应该看起来像这样…

 C:\Anthony\Demo\ExpressApp1\ExpressApp1>npm init This utility will walk you through creating a package.json file. It only covers the most common items, and tries to guess sane defaults. See `npm help json` for definitive documentation on these fields and exactly what they do. Use `npm install <pkg> --save` afterwards to install a package and save it as a dependency in the package.json file. Press ^C at any time to quit. name: (ExpressApp1) version: (0.0.0) description: entry point: (app.js) test command: git repository: keywords: author: license: (ISC) About to write to C:\Anthony\Demo\ExpressApp1\ExpressApp1\package.json: { "name": "ExpressApp1", "version": "0.0.0", "description": "", "main": "app.js", "dependencies": { "express": "~3.4.4", "jade": "~1.1.5", "stylus": "~0.42.2" }, "devDependencies": {}, "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "author": "", "license": "ISC" } Is this ok? (yes) 

如果由于某种原因， npm init不起作用，可以将以下文本保存到项目根目录下名为package.json的文件中，并更新值以匹配项目中的包。

 { "name": "ExpressApp1", "version": "0.0.0", "description": "", "main": "app.js", "dependencies": { "express": "~3.4.4", "jade": "~1.1.5", "stylus": "~0.42.2" }, "devDependencies": {}, "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "author": "", "license": "ISC" } 

第三个选项是删除项目中的npm_modules文件夹。 然后，你可以右键单击解决scheme资源Manage npm modules...器中的npm “文件夹”，select“ Manage npm modules... ，然后重新安装软件包。 以这种方式安装它们应该为你创build一个package.json 。
