Package-buffer-info: Package lacks a file header

[Thierry Leurent]

Hello,


I try to make a Melpa package for the first time. I follow the documentation 
https://orgmode.org/worg/org-tutorials/melpa-github.html

When I try to install my package using package-install-file 
recipes/belgian-holidays

I have this following message "package-buffer-info: Package lacks a file 
header".


I make a flycheck, It don't see error.


Do you have an idea ?


Thanks,

Thierry
