如何加載mongodb包？

Question

我真的很困惑在我的symfony中安裝mongodb。當我刷新我的網站時，我總是得到這個錯誤，我不知道MAMP是否是這個錯誤的一部分。

Attempted to load class "DoctrineMongoDBBundle" from namespace "Symfony\Bundle\MongoDBBundle" 

在我的composer.json中。我已經將這些代碼添加到composer.json文件中。

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

但是當我更新使用此作曲家更新作曲家。我總是得到這些錯誤。我不需要修復哪一個。我已經安裝了mongodb。

我將我的文件添加到htdocs文件夾中的MAMP。我錯過了關於mongodb到MAMP設置的一些事情嗎？或者symfony的版本對這些錯誤至關重要？

的重要組成部分，從作曲家的輸出

學說/ MongoDB的1.3.0要求EXT-蒙戈^ 1.5 - >請求的PHP擴展蒙戈從系統中丟失。

它告訴你ext-mongo從你的系統中丟失。由於ODM及其捆綁軟件無法安裝，因此您所看到的類錯誤確實不存在。你可以找到ext-mongo的安裝指南here。
