Laravel 4: Class 'MongoClient' Not Found
提问by PeterKA
I have Laravel 4 installed on WAMP and it works great with a MySQL backend.
我在 WAMP 上安装了 Laravel 4，它与 MySQL 后端配合得很好。
I have successfully setup second virtual host and would like to use a MongoDBbackend. After searching around I found out that Laravel does not natively connect to MongoDB and I found https://github.com/jenssegers/Laravel-MongoDBand I have been trying to set it up but I can't seem to get it right. Obviously I must be doing something wrong and I am hoping someone can help me identify what it is that I am not doing right.
我已成功设置第二个虚拟主机并想使用MongoDB后端。四处搜索后，我发现 Laravel 本身并没有连接到 MongoDB，我找到了https://github.com/jenssegers/Laravel-MongoDB，我一直在尝试设置它，但似乎无法正确设置。显然我一定是做错了什么，我希望有人能帮助我确定我做错了什么。
I edited composer.jsonper the instructions:
我composer.json按照说明进行了编辑：
............
"license": "MIT",
"require": {
"laravel/framework": "4.1.*",
"jenssegers/mongodb": "*"
},
"autoload": {
.........
Then I ran composer update. It installed monolog 1.9.1 and swiftmailer v5.2.0 - whatever these are - successfully (a few days ago) but then threw an error after that. Today I tried to run composer updateagain, and it updated the two to 1.10.0 and v5.2.1 respectively and then encountered the same error. Now when I try composer updateit consistently throws the same error:
然后我跑了composer update。它安装了 monolog 1.9.1 和 swiftmailer v5.2.0 - 不管这些是什么 - 成功（几天前）但之后又抛出了一个错误。今天composer update再次尝试运行，将两者分别更新为1.10.0和v5.2.1，然后又遇到同样的错误。现在，当我尝试composer update它时，它始终会抛出相同的错误：

What I have tried:
我尝试过的：
I have downloaded and installed the php_mongo.dll by placing it in the php ext folder and enabling it in php.ini:
我已经下载并安装了 php_mongo.dll，方法是将它放在 php ext 文件夹中并在 php.ini 中启用它：
; added for mongoDB connections
extension=php_mongo.dll
But this did not help.
但这没有帮助。

NOTE:I would not have been able to resolve the issue completely without @Hassan 's help -- please see comments under @Hassan 's answer.
注意：如果没有 @Hassan 的帮助，我将无法完全解决这个问题——请参阅 @Hassan 回答下的评论。
I'll provide this answer in the hopes that it may help someone else who may experience the same issue. I thought it better to give it as an answer so that it stands out.
我将提供此答案，希望它可以帮助可能遇到相同问题的其他人。我认为最好将其作为答案给出，以使其脱颖而出。

The following command and output indicates the location of php.inithat I should have updated with the php_mongo.dllextension:
进一步搜索将我带到这里：https: //github.com/jenssegers/Laravel-MongoDB/issues/36然后在这里：https: //github.com/leroy-merlin-br/mongolid-laravel#troubleshooting
以下命令和输出表示php.ini我应该用php_mongo.dll扩展名更新的位置：
$ php -i | grep 'Configuration File'
Configuration File (php.ini) Path => C:\Windows
Loaded Configuration File => C:\wamp\bin\php\php5.5.12\php.ini
The WAMPtray icon however points to C:\wamp\bin\apache2.4.9\bin\php.ini-- which is what I had updated. I also checked if PHP in the CLI environment is importing the driver properly by running the following command with the output shown:
WAMP然而，托盘图标指向C:\wamp\bin\apache2.4.9\bin\php.ini- 这是我更新的内容。我还通过运行以下显示输出的命令来检查 CLI 环境中的 PHP 是否正确导入驱动程序：
$ php -i | grep 'Mongo'
MongoDB Support => enabled
After updating the correct php.ini, I restarted apacheand tried again composer updateagain. The error was different -- authentication -- as the username, password and database were wrong. Once those were corrected, the update completed without incident.
更新正确后php.ini，我restarted apache又试了composer update一次。错误是不同的——身份验证——因为用户名、密码和数据库是错误的。一旦这些问题得到纠正，更新就顺利完成了。

Your composer file looks fine, as is probably everything else. Try a "composer dumpautoload", from the docs:
您的 Composer 文件看起来不错，其他一切都一样。尝试使用文档中的“ composer dumpautoload”：
If you need to update the autoloader because of new classes in a classmap package for example, you can use "dump-autoload" to do that without having to go through an install or update.
例如，如果由于类映射包中的新类而需要更新自动加载器，则可以使用“dump-autoload”来执行此操作，而无需进行安装或更新。
This should fix that error, after which you'll need to change your adapter in app/config/database.phpto use mongodblike so:
这应该可以修复该错误，之后您需要将适配器更改app/config/database.php为如下使用mongodb：
'default' => 'mongodb',
And add mongodb to your connections too:
并将 mongodb 添加到您的连接中：
'connections' => array(
...
'mongodb' => array(
'driver' => 'mongodb',
'host' => 'localhost',
'port' => 27017,
'username' => '',
'password' => '',
'database' => 'test'
),
),
