Root Cause

Network egress to pypi.org is blocked or slow (firewall, VPN, DNS), so each connection attempt times out before the HTTP handshake completes.

generic

中文

到 pypi.org 的网络出口被阻止或较慢（防火墙、VPN、DNS），因此每次连接尝试在 HTTP 握手完成前就超时。

Workarounds

  1. 92% success 
    export PIP_INDEX_URL=https://mirror.corp.example/simple
export PIP_TRUSTED_HOST=mirror.corp.example
python -m pip install requests
  2. 88% success 
    export HTTPS_PROXY=http://proxy.corp.example:3128
export HTTP_PROXY=http://proxy.corp.example:3128
python -m pip install requests

Dead Ends

Common approaches that don't work:

  1. 80% fail

    If the host is unreachable, a longer timeout just makes the failure slower.

  2. 85% fail

    More retries on a blocked route amplify the delay without success.
