Symfony 2 - 尝试调用函数“apcu_fetch”来自命名空间“Doctrine\Common\Cache” [英] Symfony 2 - Attempted to call function "apcu_fetch" from namespace "Doctrine\Common\Cache"

问题描述

我在symfony项目中使用PHP7.0.8和教学缓存（与APCU）。当我从使用这个缓存的控制器调用函数时，没有问题，它工作正常！

I'm using PHP7.0.8 and the doctrine cache (with APCU) in my symfony project. When I call function from my controllers which use this cache, no problems, It works fine !

但是当我创建一个使用使用了doctrine缓存的存储库的命令文件，当我在我的shell上运行这个命令时，我有错误：

But when I create a command file which use a repository which use the doctrine cache, and when I run this command on my shell, I've the error :

[Symfony\Component\Debug\Exception \UndefinedFunctionException]

尝试从命名空间Doctrine\Common\Cache调用函数apcu_fetch。

[Symfony\Component\Debug\Exception\UndefinedFunctionException]
Attempted to call function "apcu_fetch" from namespace "Doctrine\Common\Cache".

我的配置：

doctrine:
dbal:
    driver:   pdo_mysql
    host:     "%database_host%"
    port:     "%database_port%"
    dbname:   "%database_name%"
    user:     "%database_user%"
    password: "%database_password%"
    charset:  UTF8
orm:
    auto_generate_proxy_classes: "%kernel.debug%"
    entity_managers:
        default:
            auto_mapping: true
            mappings:
                StofDoctrineExtensionsBundle: ~
            metadata_cache_driver: apcu
            query_cache_driver: apcu
            result_cache_driver: apcu

如果我在控制器中运行相同的代码（
我认为这是一个错误，任何想法？

The same code works if I run it in a controller :( I think it's a bug, any idea ?

推荐答案

我通过在我的ubuntu机器上安装并启用php-apcu来修复同样的问题。 >

I fixed the very same problem by installing AND enabling php-apcu on my ubuntu machine.

sudo apt-get install -y php-apcu

不要忘记启用该模块：

sudo phpenmod apcu

双重检查php-apcu是否被加载到您的php配置的命令行版本中。尝试在命令行上运行以下命令

Double check that php-apcu is loaded in the command line version of your php config. Try to run the following on the command line

php -i | grep apcu

我有这样的输出：

/etc/php/7.0/cli/conf.d/20-apcu.ini,
apcu

其中显示apcu已加载。

which shows me that apcu is loaded.
