Bench Init error - bench 5.28

Frappe Framework
1

Trying to initialize a bench on a GCP VM.

OS - ubuntu 22.04LTS.
Bench version 5.28
Python 3.10 (though i have tried 3.14, and a few other configurations)

everything goes fine until the bench init. Throws the following error at the installing frappe stage:

× Failed to build frappe @ file:///home/sandratoolan001/frappe-bench/apps/frappe
├─▶ The build backend returned an error
╰─▶ Call to flit_core.buildapi.build_editable failed (exit status: 1)

  hint: This usually indicates a problem with the package or the build environment.

Tried some obvious stuff.
bench setup requirements - throws whole bunch of uv errors, that i’d prefer to not chase as i’m on fourth vm diag attempt.s
This config is solid generally - i’m thinking its frappe not me :wink: anybody else having the problem.
anybody got any ideas please?

Use this command for bench init:

bench init --python python3.14 develop

and in apps’s choose virtual env with 3.14

Also, update node to 24

Try this script if and let us know if you face the same problem

Please share what error you’re facing with python 3.14 - this won’t be the error. 3.14 is required for develop branch / version 16.

Sorry i did resolve manage to resolve it, but message was in moderation so i couldn’t update here.

what solved my immediate problem was running a bench init with a version specified:

bench init –frappe-branch version-15 frappe-bench

that stopped the init breaking. Obviously v16 has new dependencies which i’m still getting bitten by as i did a bunch of work locally and when i wanted to restore cloud side, i discovered the backups were v16 whereas the config i’m running in GCP is 15.93, i think. Locally i had run a few bench updates when it reminded me, but nothing special that i can remember - but i can be wrong on this, may have been warning somewhere i ignored as i was playing in my local devtest.
So the work involved some app build and i brought in a bunch of data, all local and now i’m working my through the forced restore cloud side as its swearing at me. I’m new to the space - we bump our heads, we learn :wink:
