錯誤在Symfony中安裝Doctrine-odm MongoDb

Question

我對mongoDb和Symfony的問題很少。 我安裝了php驅動1.6.12，我想安裝mongoDbBundle

在我的composer.json中添加這些行

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

}

接着

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

但我有這些錯誤

Your requirements could not be resolved to an installable set of packages.

    - doctrine/mongodb 1.2.1 requires ext-mongo ^1.2.12 -> the requested PHP extension mongo is missing from your system.
    - doctrine/mongodb 1.2.0 requires ext-mongo ^1.2.12 -> the requested PHP extension mongo is missing from your system.
    - 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

如您所見， doctrine/mongodb-odm依賴項需要在PHP安裝中安裝和啟用mongo PHP擴展 。

您可以通過查看php.ini文件和/或使用phpinfo()的頁面來檢查是否擁有它。 如果未安裝/啟用，則必須執行此操作，否則無法安裝這些依賴項。
