Answer 1

npm install命令安装用package.json文件编写的节点包，例如你有package.json：

{
    "name": "application-name"
  , "version": "0.0.1",
  "main": "app.js"
  , "dependencies": {
      "express": "*"
    , "jade": "*"
    ,"cookie-parser":"*"
  },
  "scripts": {
    "start": "node app.js"
  }
}

当你编写npm install时，它会安装依赖表达jade和cookie-parser 你收到这个错误，因为你没有package.json所以如果你想安装没有package.json的这个包，你必须写： npm安装快递 npm安装玉器 npm install cookie-parser

Answer 2

根据您收到的错误类型，您可以确定在您键入npm install 的目录中没有package.json文件。您应首先使用npm init创建必要的package.json文件，然后键入npm install。

nodejs触发“npm install”时无法读取依赖项
