打开命令提示符并进入项目目录（您可以在解决方案资源管理器中右键单击该项目，然后选择Open command prompt from here...）。

键入npm init并在提示时填写字段（或点击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.

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，您可以将以下文本保存到项目根目录中名为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，您可以右键单击解决方案资源管理器中的npm“文件夹”，选择Manage npm modules...，然后重新安装软件包。以这种方式安装它们应该为您创建package.json。
