Firebase serve command gives HTTP Error: 500, Internal error encountered - firebase

Question

I am a beginner on Firebase, I got a error when write command line "firebase serve".On the other hand, I can run "firebase deploy" command.Is this problem about OAuth 2.0 authentication ?
I am not developing ios, android app. I have been doing web site.
