My Node js config is

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

The issue got resolved after i set the following two properties:

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

Answer 2

Issue is due to windows http_proxy environment variable being set; while I don't use a proxy.

Following command in command prompt will display, if http_proxy is set;

set http

If set removed the variable with below command and problem solved.

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

Just want to share a method,the way i followed to get it resolved,

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

[username of the previous proxy]

where my .npmrc file contains registry="http://registry.npmjs.org/" and other variables[prefix,cwd,home]

As i am not behind the proxy, removed proxy variables still got the same error

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

Hence , i added the line in init() of request.js

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

then it started working!!!

PS: Once after install command,Removed this line and it continued to work. Try this , if no other options are working

Answer 4

If you're on a Linux box make sure you set the following variables:

export http_proxy="http://yourCompanyProxy:portNumber"
export https_proxy="http://yourCompanyProxy:portNumber"
export HTTP_PROXY="http://yourCompanyProxy:portNumber"
export HTTPS_PROXY="http://yourCompanyProxy:portNumber"
