You’re not in a bench virtualenv right now. source env/bin/activate fails because ~/frappe-bench/env doesn’t exist, and pip -V shows you’re using global pyenv pip. Also you’re still on Frappe version-15 (v15.96.0). Please follow the guide and don’t skip any of the steps

[image] Rick-Hard89: grep -n ‘requires-python’ pyproject.toml OK will try again

One problem I could not solve is: /opt/nexterp/frappe-bench/env/bin/python: Error while finding module specification for ‘frappe.utils.bench_helper’ (ModuleNotFoundError: No module named ‘frappe’) This error comes after bench update –patch

That error means your bench venv exists, but frappe is not installed inside it, so bench can’t import frappe.utils.bench_helper. Fix: cd /opt/nexterp/frappe-bench source env/bin/activate pip install -U pip wheel setuptools pip install -e apps/frappe pip install -e apps/erpnext pip install -e apps…

If you read the comments on the guide you can see another user that had the same problem and what we discussed.

frappe v16 works perfect with python 3.14.2. frappe v16 wont work with any older versions than v 3.14.
