Even after installing python2 this failed

Yes, You can try to update dependencies and have to update gulp-sass with sass ( npm install sass gulp-sass --save-dev )

autoprefixer ^10.2.6 → ^10.3.3
browser-sync ^2.26.14 → ^2.27.5
cssnano ^5.0.6 → ^5.0.8
gulp-postcss ^9.0.0 → ^9.0.1
gulp-sass ^4.1.0 → ^5.0.0
node-sass ^6.0.0 → ^6.0.1
postcss ^8.3.5 → ^8.3.6
apexcharts ^3.26.2 → ^3.28.1
bootstrap ^5.0.1 → ^5.1.0
prismjs ^1.23.0 → ^1.24.1

I fixed the bug and updated all dependencies in the package.json file.
