在Symfony中安装Doctrine-odm MongoDb时出错

Question

我对mongoDb和Symfony几乎没有什么问题。我安装了php driver 1.6.12，我想安装mongoDbBundle

将这些行添加到我的composer.json中

{
"require": {
    "doctrine/mongodb-odm": "~1.0",
    "doctrine/mongodb-odm-bundle": "~3.0"
},

}

然后

php composer.phar update doctrine/mongodb-odm doctrine/mongodb-odm-bundle

但是我有这些错误

    - Installation request for doctrine/mongodb-odm ~1.0 -> satisfiable by doctrine/mongodb-odm[1.0.0, 1.0.1, 1.0.2, 1.0.3, 1.0.4].

Answer 1

如您所见，要在doctrine/mongodb-odm安装中安装和启用的PHP requires mongo PHP extension。

您可以通过查看您的php.ini文件和/或使用phpinfo()的页面来检查您是否拥有它。如果它没有安装/启用，你必须这样做，否则你不能安装这些依赖项。
