Question

我正在尝试按照快递网站指南

中提到的说明在我的Windows终端中安装快递

1首先，我在package.json文件中创建了一个目录节点。

我的package.json如下

{
  "name": "hello-world",
  "description": "hello world test app",
  "version": "0.0.1",
  "private": true,
  "dependencies": {
    "express": "3.x"
  }
}

然后我尝试运行命令

npm install

但收到以下错误

E:\myFindings\nodejs_programs\node>npm install
npm http GET https://registry.npmjs.org/express
npm http GET https://registry.npmjs.org/express/-/express-3.4.8.tgz

我无法理解是什么问题，请帮我整理一下

我甚至尝试在不使用.json文件的情况下安装express，但得到相同的错误

我的npm配置列表的内容

E:\myFindings\nodejs_programs\node>npm config list
; cli configs

; userconfig C:\Users\sudipkumars\.npmrc
https-proxy = "http://sudip:sudip7@proxy:8086/"
proxy = "http://sudip:sudip7@proxy:8086/%20strict-ssl%20=%20false"
registry = "https://registry.npmjs.org/"

; builtin config C:\Program Files\nodejs\node_modules\npm\npmrc
prefix = "C:\\Users\\sudipkumars\\AppData\\Roaming\\npm"

; node install prefix = C:\Program Files
; node bin location = C:\Program Files\nodejs\\node.exe
; cwd = E:\myFindings\nodejs_programs\node
; HOME = C:\Users\sudipkumars
; 'npm config ls -l' to show all defaults.

我尝试了你的建议

npm config set registry http://registry.npmjs.org/

，输出

E:\myFindings\nodejs_programs\node>npm install express
npm http GET http://registry.npmjs.org/express
npm http 304 http://registry.npmjs.org/express
npm http GET http://registry.npmjs.org/express/-/express-3.4.8.tgz

Answer 1

在理解问题方面。问题在于您的计算机无法与https://registry.npmjs.org/express/-/express-3.4.8.tgz

建立连接

它正在尝试使用HTTP GET方法从NPM注册表中的服务器检索文件，但它似乎已超时：

npm http GET https://registry.npmjs.org/express/-/express-3.4.8.tgz
npm ERR! Error: tunneling socket could not be established, cause=connect ETIMEDOUT

这可能有几个原因，但我会提到两个主要原因：

npmjs.org的停机时间，可以使用http://status.npmjs.org/
你是一个阻止这个

查看你的npm配置：

除非你有一个名为proxy的代理设置，否则这将不起作用。所以清除代理变量集
使用npm config set strict-ssl false
如果这两个不起作用，请尝试使用npm config set registry http://registry.npmjs.org/

Answer 2

我通过发出以下命令解决了这个问题

string json = ...
var model = JsonConvert.DeserializeObject<MyModel>(json);

Answer 3

运行以下命令

npm install express

Answer 4

解决方法：npm config set registry=http://registry.npmjs.org/效果很好。

使用package.json文件或不使用package.json文件安装express时出错
