pip:python twisted包不从indexu安装

Question

背景

我有一个名为https://pipmirror.company.com的内部pypi镜像，我的pip.conf配置如下

$ cat ~/.config/pip/pip.conf
[global]
index-url = https://pipmirror.company.com/simple
cert = /etc/pki/tls/cert.pem
log = /home/hanxuel/.config/pip/pip.log
bash-4.2$ cat incremental-pip.log |xclip

Pypi上的所有包都是镜像的。你知道吗

扭曲/增量包

当我安装Twisted包时，我特别相信incremental依赖关系，pip将尝试从https://pypi.python.org而不是https://pipmirror.company.com获取
