Cannot install botocore 1.25.12 with pip

Describe the bug

When I run pip install botocore==1.25.12 I get an error:

Could not find a version that satisfies the requirement botocore==1.25.12 (from versions: 0.4.1, 0.4.2, ..., 1.25.11)

Expected Behavior

It should be installed without warning.

Current Behavior

pip install botocore==1.25.12 -v

pip.log

Based on the logs pip collects the available versions from this URL: https://pypi.org/simple/botocore/. When I open this website manually, I also don’t see the mentioned version.

Versions on this page:

...
botocore-1.25.9-py3-none-any.whl
botocore-1.25.9.tar.gz
botocore-1.25.10-py3-none-any.whl
botocore-1.25.10.tar.gz
botocore-1.25.11-py3-none-any.whl
botocore-1.25.11.tar.gz
botocore-1.25.12-py3-none-any.whl

Note that botocore-1.25.12.tar.gz is missing.

I don’t know in which system the error lies, but you might have some control over it.

Ah, I believe you have a few options. If you’re using Python 2.7, we haven’t released a version of Boto3 or the CLI that’s compatible since July of 2021. Pinning your installs to awscli<1.20 and botocore<1.21 (boto3<1.18 if needed) should stop pip from trying to grab the latest version and backtracking.

A second fix is pip 9.0.2 and later should never try to grab this version of botocore for you. I would recommend trying to upgrade that if possible as it should mitigate the issue as well.

Let us know if you have any other questions or comments on the above options.

Hi @bencehornak-gls, this is a bug in the CDN fronting PyPI. There’s an open tracking ticket in Warehouse (pypa/warehouse#10390), the system that PyPI is built on. We unfortunately have no control over fixing this. It will be resolved either when the CDN cache refreshes, or when we publish a new package (which is generally every weekday by 13:00 PT).

What’s interesting here is that the wheel is available but pip isn’t using it. All versions of pip released with Python 3.7+ should be defaulting to using the wheel. Could you provide more information about your environment (Python version, pip version, any global pip settings you’ve changed)?
