異常緣由：

公司設置了上網代理，經過nmp安裝express模塊，代理錯誤

解決辦法：

1，從新設置代理

http://manjeshpv.com/： npm config set proxy http://192.168.1.1:8080(代理服務器：端口)

npm config set https-proxy http://proxy-domain.com:8080 (代理服務器：端口)

2,選擇http方式

npm config set registry=「http://registry.npmjs.org」//設置npm源地址

3,公司的網絡可能須要驗證http://www.cnblogs.com/chrischeng/archive/2013/03/22/2975235.html：

set http_proxy_user=username

set http_proxy_password=password

4，還有建議說將proxy set null

 

1.原npm地址

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

2.設置國內鏡像

a.經過config命令

npm config set registry https://registry.npm.taobao.org 
npm info underscore （若是上面配置正確這個命令會有字符串response）

b.命令行指定

npm --registry https://registry.npm.taobao.org info underscore 

c.編輯 ~/.npmrc 加入下面內容

registry = https://registry.npm.taobao.org

3.使用nrm管理registry地址

a.下載nrm

npm install -g nrm

b.添加registry地址

nrm add npm http://registry.npmjs.org

nrm add taobao https://registry.npm.taobao.org

c.切換npm registry地址

nrm use taobao

nrm use npm

搜索鏡像: https://npm.taobao.org
