您好我是新来的节点JS，我试图按照书中的样品，并尝试做NPM安装我收到以下错误时：

任何帮助将是高度赞赏

我的节点JS的配置是

C:\Developer\NODE_JS>npm config list 
; cli configs 
registry = "http://registry.npmjs.org/" 

; userconfig C:\Users\<uname>\.npmrc 
https-proxy = "proxy.<comp>.com:8080" 
proxy = "proxy.<comp>.com:8080" 
registry = "http://registry.npmjs.org/" 

; builtin config undefined 
prefix = "C:\\Users\\puppalap\\AppData\\Roaming\\npm" 

; node bin location = C:\Program Files\nodejs\\node.exe 
; cwd = C:\Developer\NODE_JS 
; HOME = C:\Users\<uname> 
; 'npm config ls -l' to show all defaults. 

Answer 1

后，我设置以下两个属性的问题得到了解决：

npm config set proxy http://usr:pwd@host:port 
npm config set https-proxy http://usr:pwd@host:port 

Answer 2

问题是由于设置了windows http_proxy环境变量;而我不使用代理。

如果设置了http_proxy，将显示命令提示符中的以下命令;

set http 

如果设置删除变量与下面的命令和问题解决。

set http_proxy= 

Above command will remove the http_proxy from the current command line. However, if you need to permanently remove it, just remove it from System Properties>Advanced Tab>Environment Variables dialog box.

Answer 3

想和大家分享的方法，我也跟着的方式，寻求解决办法，

My error: was ERR! Error: Invalid protocol : myusername:

[以前代理的用户名]

在我的.npmrc文件 包含注册表=“http://registry.npmjs.org/” 和其他变量[前缀，密码，主页]

因为我不是代理的背后，除去代理变量 还是得到了同样的错误

when looked into request.js[/usr/lib/node_modules/npm/node_modules/request/request.js] file it is using the old proxy values

因此，我加入的init（）request.js的

self.proxy="http://registry.npmjs.org/" //at the start of method 

然后它开始行加工！！！

PS：一旦安装命令后，删除此行，它继续工作。 尝试这个，如果没有其他选项正在工作
