[BUG] npm outdated ignores proxy and registry configs

[yousifalraheem]

Current Behavior:

Runing npm outdated will throw an error ignoring the proxy and registry configurations. After upgrading to npm 7, I was unable to run npm outdated anymore.

Expected Behavior:

Should work as intended showing the outdated dependencies.

Steps To Reproduce:

Steps to reproduce the behavior (You need to run this behind corporate VPN and registry):

1. Set up the proxy and registry settings in the global npm config
2. Navigate to any project with a valid package.json that has dependencies
3. Run 'npm outdated'
4. See error...

Environment:

• OS: Windows 10 Version 1803 Build 17134.1792
• Node: 15.0.1
• npm: 7.0.5

@yousifalraheem can you try updating your version of v7 (ie. npm i -g npm@7) & trying again? We've fixed a few bugs around setting proxies.

@darcyclarke I am on npm 7.4.2 and Node 15 and I am still facing the same issue. I am behind a proxy. npm install and npm update works fine but npm outdated will throw getaddrinfo ENOTFOUND for registry.npmjs.org.

I've just attempted this. Using npm i -g npm@7 fails however npm i -g npm@latest seems to have resolved the issue.
(Tested with v15.6.0 and v15.4.0 on Windows 10).

@thirteen-io fails how? using “latest” right now installs npm 6.

@ljharb Sorry for not being clear.
It failed exactly like the original issue posted. (ENOTFOUND etc)

You are also correct regarding the latest release... totally my mistake sorry. I thought latest was using npm 7. It is at least a temporary workaround for now if you absolutely need the outdated command.

@thirteen-io Using npm 6 is not a workaround if you want to use workspace which only available on npm 7. My workaround is npm-check-updates. It updates packages in package.json to latest version and I just diff the versions change.
