我正在使用本教程https://symfony.com/doc/master/bundles/DoctrineMongoDBBundle/installation.html#install-the-bundle-with-composer 谢谢 https://www.php.net/manual/en/mongodb.installation.windows.php

【问题讨论】：

您阅读了该错误消息的哪些部分？您尝试过什么来解决这些错误？
嗨，是的，我现在需要最新的学说/mongodb-odm，但我不知道如何编写或解决此问题。我需要知道命令。谢谢

标签： php mongodb symfony composer-php

【解决方案1】：

正如您在输出中看到的那样，composer 尝试安装 doctrine/mongodb-odm-bundle，这取决于 doctrine/mongodb-odm，这需要在您的系统上安装 mongodb 扩展版本 1.5+。

教程中的提示

那么，让我们去https://docs.mongodb.com/drivers/php#installation :)

您好，抱歉，它不工作。我习惯了Flex。这个命令：composer config extra.symfony.allow-contrib true 之后我曾经作曲家需要学说/mongodb-odm-bundle。但我犯了同样的错误。
你安装并启用了mongodb吗？ php --ri mongodb 的输出是什么？ @VojtěchJanoušek
您好，感谢您的重播。在 bash 中获取：vjanousek@localhost test]$ php --ri mongodb Extension 'mongodb' 不存在。现在我在 Windows 上创建新项目，我遇到了同样的问题。
试试这个php.net/manual/en/mongodb.installation.windows.php
您好，我为手册添加了扩展名。看看我的第一条评论：php.net/manual/en/mongodb.installation.windows.php 我得到了相同的错误和新错误：composer 需要学说/mongodb-odm-bundle PHP 警告：PHP 启动：无法加载动态库 'php_mongodb.dll'（试过：C:\ xampp\php\ext\php_mongodb.dll (Uveden├Ż modul nebyl nalezen.)
