使用package.json文件或不使用package.json文件安裝Express時出錯

Question

我正在嘗試按照Express網站指南中提到的說明在Windows終端中安裝Express

1首先，我在該package.json文件中創建了一個目錄節點。

我的package.json如下

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

然后我嘗試運行命令

npm install

但是出現以下錯誤

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

我無法理解問題所在，請幫助我進行解決

我什至嘗試在不使用.json文件的情況下安裝express，但出現相同的錯誤

我的npm配置列表的內容

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.

我嘗試過你的建議

npm配置設置注冊表http://registry.npmjs.org/

和輸出是

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

在理解問題上。 問題在於您的計算機無法與以下設備建立連接： https : //registry.npmjs.org/express/-/express-3.4.8.tgz

它正在嘗試使用HTTP GET方法在NPM注冊表中從服務器檢索文件，但似乎已超時：

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

這可能是出於幾個原因，但我將提及兩個主要原因：

1. npmjs.org的停機時間，可通過http://status.npmjs.org/輕松檢查
2. 您在防止這種情況的代理人背后

查看您的npm配置：

• 除非您有一個稱為proxy的代理設置，否則它將無法正常工作。 所以清除代理變量集
• 使用npm config set strict-ssl false將strict SSL設置為false npm config set strict-ssl false
• 如果這兩個都不起作用，請嘗試使用npm config set registry http://registry.npmjs.org/設置為使用非加密連接

Answer 2

我通過發出以下命令解決了這個問題

npm config set proxy false
npm cache clean

Answer 3

運行以下命令

npm install express

Answer 4

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