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

Please what is the probleme ?

Answer 1

You have 2 autoload keys at line 5 and 20. There is double brackets closing the end of file at line 48 and 49

Try this json

    "license": "proprietary",
    "type": "project",
    "autoload": {
        "psr-4": {
            "": "src/",
            "VotreNamespace": "chemin/vers/la/bibliotheque"
        },
        "classmap": [
            "app/AppKernel.php",
            "app/AppCache.php"
        ],
        "files": [ "app/AppKernel.php" ]
    },
    "autoload-dev": {
        "psr-4": {
            "Tests\\": "tests/"
        },
        "files": [
