How to resolve NPM proxy Issue whilel running Node JS application

Question

I have installed Noed JS and NPM. I have cloned the repo from git and trying to run the app in local. But I am facing below proxy issue while running app.

 npm install nodemon npm ERR: code ENOTFOUND npm ERR. errno ENOTFOUND npm ERR..network request to https,//registry:npmjs.com/nodemon failed. reason, getaddrinfo ENOTFOUND 28 npm ERR..network This is a problem 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'`

I have check with proxy and it is set to below.network.

 Pinging proxy.internal.domainname.com with 32 bytes of data: Reply from <ip address="">: bytes=32 time=2ms TTL=247 Reply from <ip address="">: bytes=32 time=2ms TTL=247 Reply from <ip address="">: bytes=32 time=2ms TTL=247 Reply from <ip address="">: bytes=32 time=2ms TTL=247 Ping statistics for <ip address="">: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 2ms, Maximum = 2ms, Average = 2ms

I tried to set proxy to https://registry.npmjs.com/nodemon using below command.

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

When I run npm install after this, again I got the same error.

 npm --proxy http://registry.npmjs.org/ install npm npm ERR: code ENOTFOUND npm ERR. errno ENOTFOUND npm ERR..network request to http,//registry:npmjs.org/npm failed. reason, getaddrinfo ENOTFOUND 28 npm ERR..network This is a problem 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'`

I have tried many other workarounds from google but still facing the same proxy issue. I am just looking to run this app in local so that I can test my code in local before deploying. Am I missing something here.

Below is my sample package.json file.

Edit:

Running the npm config ls command returns the following result:

 ; cli configs metrics-registry = "http://registry.npmjs.org/async-each" scope = "" user-agent = "npm/6.13.4 node/v12.14.0 win32 x64"; userconfig C:\Users\username\.npmrc https-proxy = "http://registry.npmjs.org/" https://registry.npmjs.com/nodemon = "" key = "" registry = "http://registry.npmjs.org/" strict-ssl = false; builtin config undefined prefix = "C:\\Users\\username\\AppData\\Roaming\\npm"; node bin location = C:\Program Files\nodejs\node.exe; cwd = H:\IRB PMX Services\core\src; HOME = C:\Users\username; "npm config ls -l" to show all defaults.

Edit 2:

I have now run the following command to delete the erroneous configuration key, ie the https://registry.npmjs.com/nodemon = "" part:

npm config delete https://registry.npmjs.com/nodemon

and again ran the npm install command. But again got the proxy error as below:

 npm ERR..network request to registry.npmjs,org/async-each/@types%2fnode failed: reason. read ECONNRESET npm ERR..network This is a problem 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 ...

Answer 1

This fixed it for me:

npm config delete proxy

npm config delete http-proxy

npm config delete https-proxy

Happy coding !

Answer 2

I have resolved this issue with below steps :

1. make sure you have internet connection: ping 8.8.8.8
2. make sure you have DNS resolver working: ping www.google.com
3. make sure you can access registry.npmjs.org: ping registry.npmjs.org
4. make sure you can connect via https.

Run below command in npm command prompt or Visual Studio Code terminal.

npm config rm proxy

npm config rm https-proxy

Try in your browser: https://registry.npmjs.org/

Make sure you are trying to connected to:

registry.npmjs.org

and not to:

"registry.npmjs.org registry.npmjs.org:443"

Use below command to set registry.

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

If you are using a proxy to access the Web, then you also have to configure npm to use it. Use:

npm config set proxy http://username:password@proxyname:8080

npm config set https-proxy http://username:password@proxyname:8080

Points to remember here while setting above two values :

1. proxyname you need to check with your company network team. Enter that proxy URL in above 2 values.
2. If your password contains any special character then replace it with Encoded character. In this command you can't provide a password with special character. Replace only special character not .(dot).

   Example: password is : Welcome@12# then it will be like Welcome%4012%23.

Then try to run your npm install command and it should work.
