composer-phppsr-4

A non-empty PSR-4 prefix must end with a namespace separator

I'm trying to setup PSR-4 with Composer but I'm just getting A non-empty PSR-4 prefix must end with a namespace separator.

My autoload in my composer.json looks like this:

"autoload": {
    "psr-4": {
        "Acme\\models" : "app/models"
    }
},

app/models is empty.

What am I doing wrong? How can I fix this?

Solution

  • Someone made a comment but removed it. He mentioned I was missing \\ at the end of Acme\\models. Acme\\models\\ will get rid of the message and work as it should.
