PyPiServer debugging "could not find a version that satisfies the requirement"

Question

I'm creating a private package repository using PyPiServer. I'm serving this on one VPS instance and trying to pip install from another.

Traceback from pip:

root@managersvr:~# pip install --index-url http://<IP>:8080/simple/ global_toolkit --trusted-host <IP>
  Could not find a version that satisfies the requirement global_toolkit (from versions: )
No matching distribution found for global_toolkit
root@managersvr:~#

Server logs from PyPi:

[02/May/2020 23:57:10] "GET /simple/global-toolkit/ HTTP/1.1" 200 313

I'm struggling to debug. Steps taken so far: - I have run pip install --upgrade pip - I have navigated to the PyPi IP address in browser, which correctly displays:

Welcome to pypiserver!
This is a PyPI compatible package index serving 1 packages.

To use this server with pip, run the following command:

        pip install --index-url http://<IP>:8080/simple/ PACKAGE [PACKAGE2...]

To use this server with easy_install, run the following command:

        easy_install --index-url http://<IP>:8080/simple/ PACKAGE [PACKAGE2...]

The complete list of all packages can be found here or via the simple index.

This instance is running version 1.3.2 of the pypiserver software.

Navigating to the "here" link for a complete list of all packages yields:

Index of packages
global_toolkit.tar.gz

And navigating to the simple index yields:

Simple Index
global-toolkit

I also tried using global-toolkit instead of global_toolkit.

I am looking for steps to identify the layer at which there is an error, and debug it. Thanks.

UPDATE

I found the pip search command. The output is, strange:

(venv) root@managersvr:~# pip search --index http://<IP>:8080 global_toolkit
global_toolkit ()  -

Could it be that packages have to be of a particular format (e.g. .eggs)? — MegaIng
Possible. I'm following this tutorial though which specifies .tar.tz linode.com/docs/applications/project-management/… — Neil
You need to use the same name in the package as you use for the file I assume. (dash vs underscore) — MegaIng

I've resolved the issue. In hindsight I should have foreseen the problem. I failed to include my ext_modules value in the top level setup.py (so the cython modules weren't compiled). A good tip for debugging: use the -v flag!
