Could anybody clarify what are the requirements concerning flask ?

I don't understand anymore what is happening. I get the same error with
flask 1.0.2 and flask 0.12.4.

Best regards,

I updated flask in the virtual environnement as you can see. Is is now. But
when I install pgadmib, I get this:
pgadmin4 4.1 has requirement Flask==0.12.4, but you'll have flask 1.0.2
which is incompatible.
So what is in fact the required version of Flask for pgadmin 4 ?
