# npm安装任何包都报错的解决办法 #

不知道什么原因，安装nodejs后，用npm安装任何东西都报错：

C:\Users\Administrator>npm install express
    npm ERR! Windows_NT 6.1.7601
    npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "install" "express"
    npm ERR! node v4.4.4
    npm ERR! npm  v2.15.1
    npm ERR! code ENOTFOUND
    npm ERR! errno ENOTFOUND
    npm ERR! syscall getaddrinfo
    
    npm ERR! network getaddrinfo ENOTFOUND xn--rvg xn--rvg:80
    npm ERR! network This is most likely not a problem with npm itself
    npm ERR! network and is related to network connectivity.
    npm ERR! network In most cases you are behind a proxy or have bad network settings.
    npm ERR! network
    npm ERR! network If you are behind a proxy, please make sure that the
    npm ERR! network 'proxy' config is set properly.  See: 'npm help config'
    
    npm ERR! Please include the following file with any support request:
    npm ERR!     C:\Users\Administrator\npm-debug.log

然后查npm的配置，也是一脸懵逼

C:\Users\Administrator>npm config ls
    ; cli configs
    user-agent = "npm/2.15.1 node/v4.4.4 win32 x64"
    
    ; userconfig C:\Users\Administrator\.npmrc
    disturl = "https://npm.taobao.org/dist"
    proxy = "http://xn--rvg/"
    registry = "http://registry.npmjs.org/"
    strict-ssl = false
    unsafe-perm = true
    
    ; builtin config undefined
    cache = "C:\\Program Files\\nodejs\\node_global"
    prefix = "C:\\Program Files\\nodejs\\node_global"
    
    ; node bin location = C:\Program Files\nodejs\node.exe
    ; cwd = C:\Users\Administrator
    ; HOME = C:\Users\Administrator
    ; 'npm config ls -l' to show all defaults.

根据网上的教程，换了N种镜像，问题依旧存在

> 然后终于在网上找到个解决办法：

解决办法：
    
    1、执行：
    
    npm config get proxy
    npm config get https-proxy
    如果返回值不为null，继续执行：
    （这一步很重要，一定要保证两个命令的返回值都为null,话说回来，应该出现这个错误这两个返回值有不为null的）
    npm config set proxy null
    npm config set https-proxy null
    2、执行：
    npm config set registry http://registry.cnpmjs.org/

然后你就可以愉快的安装cnpm了

npm install -g cnpm --registry=https://registry.npm.taobao.org

然后你就可以更加愉快的用cnpm安任何东西了
