Symfony3 mongoDB 配置

Question

我正在使用 symfony3 并尝试设置 MongoDB。我正在关注 Symfony 文档 Symf Doc Mongo。

在本文档的使用 Composer 安装包部分，建议安装这两个包：

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

我正在尝试这样做，但是当我作曲家更新时，我得到了这些错误：

Problem 1
- doctrine/mongodb-odm 1.0.0 requires doctrine/mongodb ~1.2 -> satisfiable by doctrine/mongodb[1.2.0, 1.2.1, 1.2.2, 1.3.0].
- doctrine/mongodb-odm 1.0.1 requires doctrine/mongodb ~1.2 -> satisfiable by doctrine/mongodb[1.2.0, 1.2.1, 1.2.2, 1.3.0].
- doctrine/mongodb-odm 1.0.2 requires doctrine/mongodb ~1.2 -> satisfiable by doctrine/mongodb[1.2.0, 1.2.1, 1.2.2, 1.3.0].
- doctrine/mongodb-odm 1.0.3 requires doctrine/mongodb ~1.2 -> satisfiable by doctrine/mongodb[1.2.0, 1.2.1, 1.2.2, 1.3.0].

- doctrine/mongodb 1.3.0 requires ext-mongo ^1.5 -> the requested PHP extension mongo is missing from your system.
- doctrine/mongodb 1.2.2 requires ext-mongo ^1.2.12 -> the requested PHP extension mongo is missing from your system.
- 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, 1.0.5].

我不明白我应该从这里去哪里。

Answer 1

我认为您还应该通过键入 composer require alcaeus/mongo-php-adapter 来安装 alcaeus/mongo-php-adapter 包并手动添加 "provide" 部分，如果不存在，则包含内容：

   "provide": {
        "ext-mongo": "1.6.14"
    },
