And finally i do bundle exec jekyll serve, but with all themes i have this errors.

Can somebody help me? Thanks

What themes are you trying to install?
It could be they don’t have page, post, or home layouts, which is what the error is all about.

But can’t really say without knowing what the themes are.

Thanks

I test the most downloaded now im using default theme minima
