Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting

我不知道这是什么意思

这是我的 symfony composer.json 文件中的内容

"require": {
    "php": ">=5.3.3",
    "symfony/symfony": "2.3.*",
    "doctrine/orm": ">=2.2.3,<2.4-dev",
    "doctrine/doctrine-bundle": "1.2.*",
    "twig/extensions": "1.0.*",
    "symfony/assetic-bundle": "2.3.*",
    "symfony/swiftmailer-bundle": "2.3.*",
    "symfony/monolog-bundle": "2.3.*",
    "sensio/distribution-bundle": "2.3.*",
    "sensio/framework-extra-bundle": "2.3.*",
    "sensio/generator-bundle": "2.3.*",
    "incenteev/composer-parameter-handler": "~2.0",
    "doctrine/mongodb-odm": "1.0.*@dev",
    "doctrine/mongodb-odm-bundle": "3.0.*@dev"
},

Answer 1

因为在您的 composer.json 中有这样一行：“minimum-stability”：“dev”， 并且您正在尝试导入可能是 MongoDBBundle 的 beta 版本

在 require 部分尝试这些行：

"doctrine/mongodb-odm": "1.0.*@dev",
"doctrine/mongodb-odm-bundle": "3.0.*@dev"

Answer 2

您的问题是 mongo-php 扩展。 doctrine/mongodb 软件包的最新稳定版本不支持您安装的 mongodb 驱动程序版本1.5.0dev。将其降级到最新的 1.4 版本。此外，最好在 composer.json 中引用 beta 包而不是 dev：

"require": {
    "doctrine/mongodb-odm": "1.0.*@beta",
    "doctrine/mongodb-odm-bundle": "3.0.*@beta"
}

所以你的minimum-stability 可以保持stable。

Answer 3

我认为您需要从 php.ini 文件中启用 php_mongo.dll。

如果在 php.ini 文件中没有找到，则必须添加

extension=php_mongo.dll

在 php ini 文件，然后从下载 php_mongo.dll http://pecl.php.net/package/mongo/1.5.5/windows 并将其保存在 php/ext/

然后重启apache 现在它不会给出任何错误。
