Facing an npm error installing Socket.IO.
Example:
$ sudo npm add alt-socket
npm ERR! DNS lookup failure in mod_tld.js
Could this be due to firewall restrictions or npm misconfiguration?
I encountered a similar error during a previous project. In my case, DNS issues were indeed related to network restrictions at my company, and some misconfigured npm settings didn’t help. I eventually fixed it by checking my npm configuration to ensure I wasn’t using outdated proxy settings and by switching to a more reliable DNS server like Google DNS. It may also help to temporarily disable any firewall or VPN settings to see if the issue persists. I hope these steps can guide you towards a solution.
In my experience, such errors can be multi-faceted. I encountered a similar DNS issue when working with npm and found that the problem was partly due to the system’s local network configuration. It proved useful to temporarily bypass the firewall using a direct internet connection while also updating npm to the latest stable release. Additionally, verifying the configuration file for any conflicting proxy settings and resetting them resolved the inconsistency. This approach helped me determine whether the device or npm was the source of the problem.
hey, try removing your old proxy settings (npm config rm prxy & npm config rm https-prxy). i had a simlar issue and switching networks helped me figure out if the firewall was the culprit. give that a shot and let us know how it goes
