NPM doesn't install any modules: network socket hangs up - node.js

Question

Salam (means Hello) :)
I have the latest version of node.js installed on ubuntu 12.04, I'm not behind any proxies, and my network settings are correctly configured, and were intact since last time when NPM worked fine. But now NPM hangs up installation of any modules with following error:
nasser#nasser-desktop:~/projects/server v3$ npm install simple-proxy
npm WARN package.json docco#0.6.2 No repository field.
npm http GET https://registry.npmjs.org/simple-proxy

Answer 1

i had same problem.
it seems that there is some problem with ISP's https handling. doing:
npm config set registry http://registry.npmjs.org/
worked for me

Answer 2

I was having the same problem. Found a solution in this thread.
You can see the effective proxy that npm is using by doing:
npm config get proxy
npm config get https-proxy
If you're behinid a proxy, try this:
mv ~/.npmrc ~/.npmrc.bak

Answer 3

I was having a similar issue with my windows machine and i fixed it by first checking whether my proxy got some value by executing the below command.
npm config get proxy
in return i got the below:
http://usr:pwd#host/:port
So if anyone who is not under a proxy layer first set the proxy as null by executing the below command.
npm config set proxy null
now if you excecute your npm i it should not throw any network error.

Answer 4

I tried multiple solution but most of cases happened with me is network/ssl and proxy issue.Network/ssl cases are very common and there are bunch of solution but with proxy thing I shared my fixes with you.
Bash Commands:
npm config set proxy null
npm config set https-proxy null
npm config set http-proxy null
in my case I'm using https://registry.npmjs.org/ url.
After NULL proxy its start working.
npm set default proxy as http://my-proxy.com:1080/ so either we have to change proxy url or null it.
To get your default proxy hit below command in your bash.
npm config get proxy

Answer 5

If you are behind a proxy that has username and password authentication, try setting the proxy as
npm config set proxy http://username:encodedpassword#proxyaddress:port
npm config set https-proxy http://username:encodedpassword#proxyaddress:port

Answer 6

Just follow these steps before you run: npm install -g #angular/cli
npm cache clean (You can even ignore if it throws an error)
npm config set strict-ssl false
npm config set proxy http://myusername:mypassword#proxyaddress:port
npm config set https-proxy http://myusername:mypassword#proxyaddress:port

Answer 7

Add the proxy and http_proxy field with your credentials (encoded if it contains any special characters) to your .npmrc file and run npm install again. It should work.
for example:
proxy=http://username:passcode#proxyURL:80/
https_proxy=http://username:passcode#proxyURL:80

Answer 8

Find .npmrc file, open with note pad. then delete the proxy setting there
