Running 'jay' hangs for ~3 minutes when running behind network proxy on Windows

[rsify]

can't reproduce this myself unfortunately - does installing modules via jay work for you when behind the proxy?

$ jay
> require('lodash')

I am not surprised that you cannot reproduce this :) Interestingly, after changing absolutely nothing jay is starting up right away now - no more hanging. Since I have started using jay I have consistently been having these hangs. So i'm not sure what changed. Just yesterday this was taking 3 minutes.

I thought I could require modules. I had installed lodash previously and it now loads fine from cache:

[email protected] imported from node_modules.

But maybe I had been off my network proxy when I loaded lodash the first time.

Now I cannot load any packages:

> require('ramda')

FYI, my C:\Users\jonathan\AppData\Local\jay-repl-nodejs\Cache\packages directory is empty.

I figured out the cause of the error I was getting when attempting to require un-cached packages. It turns out that npm was unable to resolve my root CA file for my proxy. That was preventing me from even being able to run npm:

After fixing that I am now back to being able to require packages. And I can still run jay quickly. It starts up right away now. I have no idea why the behavior suddenly changed. 🤷

[jonathanr24]

jay is back to taking 3 minutes to start up. I can't explain why it started up quickly previously. Can you make the change above to disable npm's update notifier (or just stop displaying the npm version)?
