Unable to set an environment variable

[andreamoro]

Description

On my Mac Sequoia 15.1 (24B83) I've been trying to set an environment variable to run when the Virtual Enviornent is activated.
Although I've edited the /Users/myuser/.pyenv/versions/3.12.1/venvs/activate file by adding a export myvariable="path/with/slashes/and with spaces" at the very next pyenv activation, the variable results empty, like the file is not executed.

As a counterproof I've edited the right file, I've renamed the activate into something different to obviously get an error message.

What is that I'm doing wrong?
