Description
In a fresh Docker container, I'm seeing a difference in the files installed between pip install X --target /tmp and pip install X --target /tmp --upgrade. My understanding of --target is that the --upgrade flag will only produce different behavior if there's already an existing installation present.
I can't determine if this due to a badly formed distribution of the project in question, a bug in pip, wheel, or a combination of them all.
(You can ignore --no-deps below, I just included it to keep the output smaller).
Behavior without --upgrade
$ docker run -it python bash
root@cdd4f75b6a82:/# ls /tmp
root@b899188462d1:/# pip install -t /tmp --no-deps teradatasql
