此外，如果您的网络防火墙阻止了对PyPi的访问，则它们最有可能阻止对VPN的访问，因此，我建议测试一下您尝试通过的VPN是否未被IP阻止. curl的另一种替代方法称为 bitsadmin ，您可以用来验证是否您可以访问vpn，或者只使用老式的ping.

Also if your networks firewall is blocking accessing to PyPi, they are most likely to block access to VPN, so I would recommend testing if the VPN you are trying to tunnel through is not blocked by your IP. There is an alternative to curl known as bitsadmin that you can use to verify if you have access to the vpn, or just use old fashioned ping.

P.S.这两个VPN都有免费层，这就是我的建议.

P.S. Both the VPN's have free tier and that is what I recommend.
