pip unable to find newest package version

I'm having an issue installing a new package version using pip.

Im working on my package, and recently uploaded a new version (==1.9.0), the same way I always do using twine upload. The upload was successful. When trying to install the new version, I get the following error:

>>> pip install the-spymaster-util==1.9.0
ERROR: Could not find a version that satisfies the requirement the-spymaster-util==1.9.0 (from versions: 0.1.1, 1.0.0, 1.1.0, 1.2.0, 1.2.1, 1.2.2, 1.3.0, 1.3.1, 1.4.0, 1.5.0, 1.6.0, 1.7.0, 1.7.1, 1.7.2, 1.7.3, 1.7.4, 1.7.5, 1.8.0)
ERROR: No matching distribution found for the-spymaster-util==1.9.0

as if version 1.9.0 doen't exist. The wierd thing is that it does exist in pypi index, just that for some reason my local index refuses to update according to it. Also, the newest version (==1.9.1 as im writing this question), does not appear as the "lastest" version - but 1.8.0 does. Usually the index updates within a few seconds after the upload is completed.

Am I missing something?

Solution

While there is probably some caching delay in pypi as mentiond in the comment by @Bijany, I did find my way around this (not production-ready, but good enough to keep local developemnt going):

Open your specific package version page in pypi (e.g. https://pypi.org/project/package_name/package_version)
Click on Download Files.
Copy the Source Distribution file URL (the .tar.gz file).
In the command line, run: pip install <file_url>.
