Unable to install packages with pip

Question

My build machine doesn't have internet connection. so i created proxy repository in nexus with name "proxy_repo" which is pointing to https://pypi.org/ . and created ~/.pip/pip.config in build machine.

https://pypi.org/ is allowed to access from build machine through nexus.

content of the pip.conf is as below

[global]
trusted-host=MyPrivate-nexusrepo.com
index = https://MyPrivate-nexusrepo.com/content/repositories/proxy_repo/pypi
index-url = https://MyPrivate-nexusrepo.com/content/repositories/proxy_repo/simple

when i execute any pip command, say "pip -v install django" , i always getting below error. can some one please help?

我之前遇到过此问题，通过设置日期和时间来解决我的问题..如果计算机的日期和时间不是最新的，它将阻止从Python.org提取数据

One thing that often trips people up who are running in restricted environments is that access to both of these servers must be allowed through your corporate firewall:

https://pypi.org/

https://files.pythonhosted.org/

The reason for this is that requests made to the first URL often redirect to the second one for the content requested.
