Thank you for the Gulp theme! Getting an error when trying to run npm install

• Tried deleting node modules for a clean reinstall
• tried deleting package-lock.json for a clean reinstall

Any ideas what could be wrong here? Likely seems likely a versioning issue with some package but no idea currently how approach with this error. Any advice?

Hi @rulloliver, try updating your versions of npm and node. I think it's what causes the errors.

[oguilleux]

careful I just saw that support for node v12 is over.

@oguilleux Thanks for this - played around got it working with updated versions. Although regarding warnings & errors (I'm a bit of monk i guess although it works):
- Deprecation Warning: $weight: Passing a number without unit % (100) is deprecated.

• although saw this will be fixed in Bootstrap 5.2.3

- ✖ 35 problems (34 errors, 1 warning)
  21 errors and 0 warnings potentially fixable with the `--fix` option.

• how did you resolve these? Seems like --fix doesn't resolve any.

Thanks for the quick discussion!

[oguilleux]

Yes it's a known issue and it will be fixed in Bootstrap v5.3.0 - meanwhile I'll downgrade sass

[oguilleux]

I don't see the

- ✖ 35 problems (34 errors, 1 warning)
  21 errors and 0 warnings potentially fixable with the `--fix` option.

I only have 1 warning when installing the project and it's the console.log I left for demo purposes.
