Install.js not respecting local npm repo

My organisation uses **Nexus** for serving npm packages. And my local npm registry is configured to use the same. Running `npm get registry` returns the Nexus registry url.

But when I do `npm install` for this repo, during the **postinstall** step of **electron** it runs the script `node install.js` which is connecting to github.com instead of the Nexus registry.

I am getting below error
RequestError: connect TOMEOUT 140.82.121.3:443

Do I need any other configuration for this?

Start with Electron's postinstall step and the install.js script mentioned in the report, then compare its registry behavior with the value returned by npm get registry. Reproduce the npm install failure against the configured Nexus registry; done means the install no longer connects to github.com or produces the reported timeout.
