使用propel bundle升级Symfony 2.7到3.0(3.1)

我正在尝试将Symfony 2.7升级到Symfony 3.0或3.1。我在我的项目中使用推进，推进束。我读了很多关于Symfony升级步骤的页面。

通过composer完成。首先，我升级了我的作曲家。

更改编写器。Json文件内容:

            "dev-master": "3.0-dev"
        }
    }
}

…我得到了升级过程的结束，推进/proepl-bundle/PropelBundle()类没有找到，但路径是正确的。

有人有过这样的经验吗?或者有什么建议吗?我试图找出哪个propelBundle版本可能是正确的。

"propel/propel": "~2.0@dev"

 public function registerBundles() {
        $bundles = array(
            ...
            new Propel'Bundle'PropelBundle'PropelBundle(),
            ...
        );
        if (in_array($this->getEnvironment(), array('dev', 'test'))) {
            ...
        }
        return $bundles;
    }
