Unable to downgrade version of Python package arrow

To temporary workaround a compatibility issue, I tried to downgrade version of Python package arrow from 0.17.0 to 0.13.2.

On a particular server I was unable to, as the below command calls to install 0.13.2 but ends up install back 0.17.0. If remove the virtual environment, and generate a new one and freshly install 0.13.2, it works OK.

I also tested on a virtual machine, and the downgrade works OK without this symptom.

I'm wondering why, and any inputs will be highly appreciated.
