Error when I use npm install with visual studio code

Question

Hello I am working on a project where I have to build an API. With node.js, express, and Mongodb.

When I install the dependencies of express or mongo db ( exemple :npm install express), I have a error.

I work with my wifi, yesterday everything was working though. I don't understand why I have this problem now. I must make configuration ? I shared an image.

I work with visual studio code. 1

check Node: npm install failure due to proxy config! What now?

and try

npm config set proxy

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

As it is stated in the error description,
"there is a problem related to network connectivity".

Probably, it's the problem with your wifi connection.

Command "npm install express" should work just fine with normal connection.

I do not understand yet I am on a normal connection, wifi. Yesterday it worked very well, I connect from my home. – ZeyennaStudy Dec 22 '21 at 23:50
Do you use a proxy or vpn? Maybe some ports are closed? – Vladimir Bakulin Dec 22 '21 at 23:54
I use my wifi (home), I installed node.js but the error contained. – ZeyennaStudy Dec 23 '21 at 00:24
You could try Rian's answer first to make sure it's not the proxy issue – Vladimir Bakulin Dec 23 '21 at 00:32
Sorry I'm just starting out, but what is written at the top by Rian's ( thank you), I have to do it on a powershell or directly on Visual studio code in my folder "backend", because nothing is displayed? – ZeyennaStudy Dec 23 '21 at 00:56
You do it in the same terminal where you execute npm install – Vladimir Bakulin Dec 23 '21 at 00:58

Solution: The proxy you are using must be configured in npm.

npm config set proxy http://your url

npm config set https-proxy http://your url

If you don't know the proxy url, you can get it through the registry, run in cmd:

regquery "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" | find /i "proxyserver"
