Please help solve issue with errors related to node-sass when running npm install

[mrosswog]

Hello, any guidance on the issues below would be greatly appreciated.

Last year we updated our theme to get rid of any incompatible scss, and were able to go the rest of 2024 with routine updates, no problems.

For 2025 we are revamping our theme, and I am starting with a new, downloaded copy of the theme files.

I completely uninstalled and re-installed the correct versions of nvm, npm, and node.js, as well as BigCommerce Stencil CLI.

I see that BC now says Python is required, so I downloaded Python 3.13.1, installed and configured my .zshrc file.

When I run npm install in my theme directory, I get some confusing error messages. There is a set of messages about node-sass, and later some about node-gyp and python:

Please, upgrade your dependencies to the actual version of core-js.

Hi @mrosswog
Do you have setuptools installed?

[mrosswog]

yes, unless i did this wrong:

python3 -m pip install setuptools
Collecting setuptools

[jairo-bc]

The actual error is ./src/libsass/src/sass.hpp:49:10: fatal error: 'string' file not found, that's something new.
Are you on Rosetta mode?

[mrosswog]

Thanks for the response
No rosetta I am on an Intel Mac
I am running Mac OS Sonoma 14.7.2
I installed Python 3 from the Python Website. Then configured an alias in .zshrc to make sure the python command calls up python3.

[jairo-bc]

@mrosswog you may try to use
python3 -m venv ~/py_envs source ~/py_envs/bin/activate before installing _ setuptools_

[mrosswog]

Thank you for the tip, but before I try this - I uninstalled version 3.13 of Python so that's now out of the picture.

I have version 3.9 and 2.7 that came with Mac OS. Do I still need to use the command you provided?

I am still experiencing the same problems trying to use the system Python.

Thank you very much
