升级后 psr4 的变化 class 未找到 symfony 2,4 -> 2,8

psr4 changes after upgrade have class not found symfony 2,4 -> 2,8

我用 "symfony/symfony": "~2.4", 和配置

"autoload": {
        "psr-0": { "": "src/", "Mea":"vendor/", "mea":"vendor/Mea/CoreBundle/", "Place":"vendor/Mea/"  }
    },

我用 "symfony/symfony" 创建新项目:“2.8.x-dev”,

首先我得到错误

[InvalidArgumentException]                                     
  a non-empty PSR-4 prefix must end with a namespace separator.

所以我加

 "autoload": {
            "psr-4": { "": "src/","Mea\":"vendor/", "mea\":"vendor/Mea/CoreBundle/", "SymfonyStandard\": "app/SymfonyStandard/" }
        },

并且有 ClassNotFoundException

当我尝试访问此文件夹中的 类 时

示例:

 $a = \mea\pattern\view::inst();

给我的

Attempted to load class "view" from namespace "mea\pattern".
Did you forget a "use" statement for "mea\pattern\view"?
500 Internal Server Error - ClassNotFoundException

如何解决?

您配置的命名空间是"Mae"(驼峰式),但在代码中您使用"mae"(小写)。 PSR-4区分大小写:

All class names MUST be referenced in a case-sensitive fashion.
