Hi all,

I am trying to create a new module for v.14 on a server following along with the book called "odoo 12 development essentials fourth edition". Reading the chapter 3, I used the scaffold, to create the folder structure for my Library module. I edited the first xml in views, and the __init__.py in the models like in p.86 of the book. Leaving the tests and security for later.

But in my odoo webpage, the Library module doesn't seem to be installed, though I see the module's card in the Apps when I type "library" in the search bar. (The install buton throw an error).

I thought I did start the server with the right database indicated (with odoo-bin -d mydatabase -i library_app ) but maybe this part didn't work out well? I believe I also used the -u later to upgrade, while I was trying to resolve this.

Thanks for your help,
have a great day everyone
