我有一个名为https://pipmirror.company.com的内部pypi镜像，我的pip.conf的配置如下
$ 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上的所有软件包都已镜像。
当我安装Twisted软件包时，特别是我相信incremental的依赖关系，pip将尝试从https://pypi.python.org而不是https://pipmirror.company.com抓取
