trying to install FOSUserBundle bundle from below link How to install 3rd party Bundles but getting this error :
[Symfony\Component\Config\Definition\Exception\InvalidConfigurationException]
The child node "db_driver" at path "fos_user" must be configured.
推荐答案
您忘记在 app/config/config.yml 中添加 FOSUserBundle 的配置或至少没有提供值对于 fos_user.db_driver.
You have forgotten to add the configuration for FOSUserBundle in your app/config/config.yml or at least did not provide a value for fos_user.db_driver.
您必须至少配置 db_driver 、防火墙和您的用户类，否则配置将抛出 InvalidConfigurationException.
You have to configure at least the db_driver , firewall and your user-class otherwise the configuration will throw an InvalidConfigurationException.
# app/config/config.yml
fos_user:
db_driver: orm # other valid values are 'mongodb', 'couchdb' and 'propel'
firewall_name: main
user_class: Acme\UserBundle\Entity\User
请参阅文档章节步骤5:配置FOSUserBundle.
