having problems with node-sass

[nikocraft]

I just bought the course, first run composer install and then tried to run yarn to get all the necessary javascript stuff. I end up with the error below. How do I get around it? Has anyone else had this? Do I actually need to run yarn to get javascript stuff or is that not required to complete the course? I'm not sure since the author does not mention these steps, I am doing what I normally do with laravel application.

Do you have Python installed?

I do now and still get new errors:

why do I need python? I got another laravel project and I do not have any problems there to build node-sass. Does this has to do with this project using gulp, since I do not use gulp in my private laravel project, but I use webpack and mix.

[EmilMoe]

And you tried npm rebuild node-sass? that solves 90% of the cases with node-sass

[nikocraft]

@EmilMoe yes that is all good, but I dont think mixing yarn and npm is good. Is there equivalent method I can use with yarn to rebuild node-sass?
