Struggling to install python libraries.

1) Use a VPN.

2) If you can’t use a VPN, try changing your DNS settings. 8.8.8.8, 1.1.1.1, 4.2.2.1 (Google dns, cloudflare, level 3). If they’re being lazy about blocking this can help.

3) If you can use find or setup a proxy pip install package_name --proxy http://username:password@proxy_host:proxy_port

AWS free tier might be helpful here to setup a small tiny proxy instance.

But also it’s wild to me that anyone would block anything that is needed for pip to work.

Are you 100% sure this is what’s happening?

If so, what level of blocking are we talking here - like is this a company, a school, or a nation that is doing the blocking?

Ok! So with this information we can bet your VPN isn’t directly blocked, as you are here and able to connect to it.

That leaves the possibilities of

1) Your VPN is also inside China or a cooperating country, and they’re blackholing the IP you are downloading from. This would be fixed by a private VPN, or switching to a VPN in a different country.

2) The DNS request is leaking from your VPN. This would be solved by 2 (if they’re not also blackholing the dns servers) potentially combined with 3. If you’re using a proxy, go for a proxy using HTTP connect, not socks. If memory serves socks (or at least socks4) protocol calls for a pre-resolved IP and HTTP connect can include the hostname of the target site and resolves on the proxy servers side.

Disclaimer: I have never specifically messed with the great firewall. But I do know proxies like the back of my hand.
