作曲家找不到mongodb扩展

Question

When executing composer require jenssegers/mongodb:

$ composer require jenssegers/mongodb
Using version ^3.0 for jenssegers/mongodb
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

Problem 1

- jenssegers/mongodb v3.0.0 requires mongodb/mongodb ^1.0.0 -> satisfiable by mongodb/mongodb[1.0.0, 1.0.1].
- jenssegers/mongodb v3.0.1 requires mongodb/mongodb ^1.0.0 -> satisfiable by mongodb/mongodb[1.0.0, 1.0.1].
- jenssegers/mongodb v3.0.2 requires mongodb/mongodb ^1.0.0 -> satisfiable by mongodb/mongodb[1.0.0, 1.0.1].
- mongodb/mongodb 1.0.1 requires ext-mongodb ^1.1.0 -> the requested PHP extension mongodb is missing from your system.
- mongodb/mongodb 1.0.0 requires ext-mongodb ^1.1.0 -> the requested PHP extension mongodb is missing from your system.
- Installation request for jenssegers/mongodb ^3.0 -> satisfiable by
  ers/mongodb[v3.0.0, v3.0.1, v3.0.2].

To enable extensions, verify that they are enabled in those .ini files

 - C:\wamp\bin\php\php5.5.12\php.ini

You can also run php --ini inside terminal to see which files are us P in CLI mode.

Installation failed, reverting ./composer.json to its original content.

I am running Windows 7 and PHP 5.5.12 use mongodb 3.2 . I installed the mongodb extension (php_mongodb.dll in PHP ext/ folder), and I've updated php.ini with extension=php_mongodb.dll. Not sure what I've missed

Answer 1

There are two kinds of drivers available at pecl

You need to install the mongoDB database driver . As you explained it looks like you have installed the mongoDB driver for PHP which is not correct

and you have to add php_mongo.dll in your php.ini

extension=php_mongo.dll

as explained here

get the proper DLL from here

You will get something like this in your phpinfo();

I hope this helps. Thanks,
