I'm no expert in these things but I suspect you may have upgraded the 
version of jinja2 in your user's pip library, but when ansible runs it is 
picking up the version installed for all users - the 'system' version.

I'm not sure how exactly you resolve this.  If you don't have root/sudo 
access and can't upgrade the system version of jinja2 then maybe you can 
install all of ansible in your users' pip library, which I think will also 
pull in the newer version of jinja2.

Another alternative might be to set up a python venv, which you can then 
install whatever versions you need into, and run ansible from inside the 
venv.

It's not something I do myself (I prefer to try and have one python and set 
of libraries for the whole virtual machine), so I can't offer advice on 
setting up the venv.

Hopefully the above will at least give you some ideas for things to try.
