Create a single page for a custom post type getting an error

i created a custom post type “portfolio” then created a single page (just copied single.blade.php) and renamed it to single-portfolio.blade.php. When i go on a single page ex:url(/portfolio/project-4) i’m getting an error NONE OF THE VIEWS IN THE GIVEN ARRAY EXIST. (VIEW: /SRV/WWW/CONSTRUCTIONASSELINETFRERES.COM/CURRENT/WEB/APP/THEMES/CONSTRUCTIONASSELIN/RESOURCES/VIEWS/SINGLE-PORTFOLIO.BLADE.PHP)
I’m using trellis acorn v.2.1.3
