GM 🌇 I am trying to setup local dev environment. Build fails on

yarn setup

with the error message.

 | 
 | Note: This error originates from the build backend, and is likely not a problem with poetry but one of the following issues with scipy (1.13.1)
 | 
 |   - not supporting PEP 517 builds
 |   - not specifying PEP 517 build requirements correctly
 |   - the build requirements are incompatible with your operating system or Python version
 |   - the build requirements are missing system dependencies (eg: compilers, libraries, headers).
 | 
 | You can verify this by running pip wheel --no-cache-dir --use-pep517 "scipy (==1.13.1)".

Hey @rapid-branch-72575, Can I know what's your current python version?

Hey @swift-queen-7691 - I am on

➜ python3 --version
Python 3.13.3

I had similar issues with 3.13. Please try downgrading python version to

3.9.6

ok, I've dev environment up and running.

Homebrew

installed python was causing issues. • downloaded and installed

.pkg

installer from

<http://python.org|python.org>

fixed it.
