The above exception was the direct cause of the following exception:

Answer 1

Seems like you're trying to install Frappe develop ([pre-]version-15) with Python 3.9 (Your tracebacks show this). However, Frappe develop has a minimum requirement of Python 3.10 as defined here in its build file.

When I want to setup a Bench for v13 Frappe that needs Python3.7, I run the following command:

bench init v13-bench-2023 --version version-13 --python $(which python3.7)

If you have 3.10 installed on your machine, find its installed path - typically by $(which python3.10), and pass it along with the bench init command.
