Question

我正在尝试验证我的Symfony 3项目但是我在编写器脚本时遇到错误：

SensioLabsInsight无法安装Composer依赖项。如果您需要自定义文件或运行命令以使其工作，您可以编辑SensioLabsInsight项目配置以覆盖默认的“pre_composer_script”和/或“post_composer_script”设置。

这是错误：

我不知道为什么SensioLabsInsight需要连接到数据库。

对我来说同样的问题，显然这个问题会影响DBAL 2.5

所以你必须在config.yml中添加服务器版本

doctrine:
dbal:
    driver:   pdo_mysql
    host:     "%database_host%"
    port:     "%database_port%"
    dbname:   "%database_name%"
    user:     "%database_user%"
    password: "%database_password%"
    charset:  UTF8
    server_version: 5.6

清除缓存后，Symfony尝试启动内核。这包括连接数据库。

安装项目的依赖项时，编译器安装执行命令。反过来，此命令执行缓存：清除命令，尝试启动应用程序的内核。

我遇到了同样的问题并且决定在我的测试环境中使用内存中的<Style TargetType="TreeViewItem"> <Setter Property="Tag" Value="{Binding RelativeSource={RelativeSource AncestorType=TreeView}}" /> <Setter Property="ContextMenu"> <Setter.Value> <ContextMenu> <MenuItem Header="Remove" cal:Action.TargetWithoutContext="{Binding Path=PlacementTarget.Tag.DataContext, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=ContextMenu}}" cal:Message.Attach="[Event Click] = [Action RemoveResource()]"/> </ContextMenu> </Setter.Value> </Setter> </Style>数据库（我已经在其他地方使用过了），但你也可以使用MongoDB，Redis或Memcached。
