I think no Bug - just a unexperienced elderly user... having Vers. 1.2.1 about bottleneck HOT 3 CLOSED

$ pip3 install bottleneck 1.3.1 no cache

Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Requirement already satisfied: bottleneck in /usr/lib/python3/dist-packages (1.2.1)
ERROR: Could not find a version that satisfies the requirement 1.3.1
ERROR: No matching distribution found for 1.3.1

Where is my mistake?

from bottleneck.

Try just to update to the latest version:
pip install -U bottleneck

Also I suggest to do this on a virtualenv (and not the system python as you are doing), to avoid disrupting your system environment.

python -m venv my_env
source my_env/bin/activate
python -m pip install bottleneck

try to use a single virtualev per project.

from bottleneck.

pip3 install -U bottleneck

did it.. works now without error. thank you sir
