symfony - composer安装程序报错，PDO我已经装了，在php.ini中也配置好了，为什么安装还报错呢？

composer require sonata-project/admin-bundle
php warning: php startup: pdo: unable to initialize module
module compiled with module api=20121212
php compiled with module api=20100525
these options need to match

Problem 1

• The requested package doctrine/orm (installed at v2.4.8, required as ^2.5) is satisfiable by doctrine/orm[v2.4.8] but these conflict with your requirements or minimum-stability.

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

• /etc/php.ini

• /etc/php.d/curl.ini

• /etc/php.d/fileinfo.ini

• /etc/php.d/json.ini

• /etc/php.d/phar.ini

• /etc/php.d/zip.ini
  You can also run php --ini inside terminal to see which files are used by PHP in CLI mode.

/etc/php.ini 看下扩展有没有开启

错误提示很明显了：

PHP Warning: PHP Startup: PDO: Unable to initialize moduleModule compiled with module API=20121212

PHP compiled with module API=20100525
These options need to match
in Unknown on line 0

你的 PDO 扩展无法加载，请重新下载对应你的PHP版本的 PDO 扩展。
