First project! Arduino uno r3 says "no matching function for call to 'SevSeg::SevSeg()'"

Question

I was following this tutorial, and everything is wired correctly as far as I can tell, but my 7seg display is only showing 8888. I tried uploading the code to the controller but I get back "no matching function for call to 'SevSeg::SevSeg()'" I'm not sure what I'm doing wrong. Any help would be greatly appreciated. Thank you!

full error message:

I noticed my links were not posted in my original post. I found that the libraries I needed were not importing correctly, more specifically the sevseg one. I needed to import another one with it. Now the 7 seg display is showing up correctly
