Code of Conduct

Looks like a connection issue to your index (aliyun?). You need to talk to either your network provider (maybe they are mangling your gzip requests) or aliyun admins (maybe they are mis-handling the gzip requests). Either way, there is little pip can do here, except maybe emitting a better error message saying the network request is corrupted.
