Python 3.12 build error "No module named 'distutils'" #28695

MikeMcC399 · 2024-01-11T15:31:15Z

Current behavior

Executing yarn to build Cypress from source causes build errors when using the current version of Python 3.12.1. The following npm modules are affected:

The error messages include the following line caused by a breaking change in Python 3.12 which is incompatible with the version of node-gyp currently used by Cypress:

ModuleNotFoundError: No module named 'distutils'

Desired behavior

CONTRIBUTING > Requirements should correctly list working prerequisites. The current text says:

python (since we use node-gyp. See their repo for Python version requirements.)
- Note for Debian-based systems: python is pre-installed.
  sudo apt install g++ make cmake meets the additional requirements to run node-gyp in the context of building Cypress from source.

The text should be changed to state that Python 3.11 is the highest version compatible with Cypress install / build from source.

Python version overview

According to https://endoflife.date/python Python 3.11 is supported until Oct 24, 2027, so there should not be any urgent need for Cypress to support Python 3.12 and later.

Defaults

OS \ Distribution	native	GitHub runner
Ubuntu `22.04`	`3.10.12`	`3.10.12`
Windows 2022	-	`3.9.13`
Windows 11	-	N/A

Deprecations

Python 3.12 introduces a breaking change:

PEP 632: Remove the distutils package. See the migration guide for advice replacing the APIs it provided. The third-party Setuptools package continues to provide distutils, if you still require it in Python 3.12 and beyond.

Support for Python 3.12 was added to node-gyp@10.0.0 (see issue nodejs/node-gyp#2869) in gyp@0.16.1 taking care of the breaking change in Python. node-gyp@10.0.0 is however not (yet) used by Cypress, meaning that Python 3.12 cannot yet be used cleanly either.

The text was updated successfully, but these errors were encountered:

I can offer to submit a PR to update the text in CONTRIBUTING > Requirements accordingly.

There is also a related issue that the version of node-gyp used by Cypress is not compatible with the Windows 11 SDK. For clarity I will submit that as a separate issue.

Edit: See also node-gyp build error "missing any Windows SDK" #28703

@MikeMcC399 Thanks, that does seem like the most reasonable PR to start.

MikeMcC399 · 2024-01-12T11:41:34Z

@jennifer-shehane

The Python default on Ubuntu is version 3.10, which works fine. It's only Windows where a user might install Python 3.12 (latest) and run into issues, however since I couldn't find a solution for node-gyp build error "missing any Windows SDK" #28703 so far, it won't be very helpful to add the Python version restriction if it still doesn't work. I'll come back to this issue if I find something more complete and usable which can be documented.

Issue node-gyp build error "missing any Windows SDK" #28703 is resolved through PRs chore(deps): refresh dockerode@3.3.1 #28726 and docs: Install Windows 10 SDK for yarn install #28760
This issue is planned to be resolved through the documentation PR docs: Python 3.11 is highest compatible version for yarn install #28759
