PIP cannot find files in server

[139167]

Description

I am trying to install some packages of Ollama, to do some API engineering. I have just updated a new verison of PIP according to the advise from PIP, installing 25.0. Later, we I start installing Ollama (Existing in pypi.org), it tells me a warning of "WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ProxyError('Cannot connect to proxy.', FileNotFoundError(2, 'No such file or directory'))': /simple/ollama/", and ultimately results in "ERROR: Could not find a version that satisfies the requirement ollama (from versions: none)
ERROR: No matching distribution found for ollama", I also test this version with PIP update, which also results in a similar error.

I tried to reinstall, the older version works perfectly, updating PIP without any problems. As soon as I reach version 25.0, it's not working. So, as a conclusion, I have a reasonable doubt of it is a problem of PIP instead of me? I'm not sure of whether it's right or not. Wish someone please help me.

The error indicates that a proxy is specified somewhere in your system and that the proxy is not responding.

Can you run pip config list, does it output anything for 25.0? If so is it different than the last working version of pip? If it is you can run pip config list -v to see if it is looking at any different files.

@notatallshaw Well, thanks for your responce.

I run the command of different versions (25.0 Not Working and 19.2.3 Working), the outputs are existing for both versions and the outputs are exactly the same.

Old Version:

New Version:

However, if you skim through the output, even it says ProxyError, but what comes later is FileNotFound, so, quite non-sence problem, lol.
