Question

我想将symfony从3.3升级到3.4但是当我执行Warning: Can only update a mounted or mounting component. This usually means you called setState, replaceState, or forceUpdate on an unmounted component. This is a no-op. Please check the code for the MyComponent component.时，我发现了这个错误：

composer update

在浏览器中，有2条消息：

[RuntimeException]
An error occurred when executing the "'cache:clear --no-warmup'" command:
PHP Fatal error:  Uncaught Symfony\Component\Debug\Exception\UndefinedMethodException: Attempted to call an undefined method named "getDefaultName" of class "Doctrine\Bundle\DoctrineCacheBundle\Command\ContainsCommand". in /srv/http/ocim.formations/vendor/symfony/symfony/src/Symfony/Component/Console/DependencyInjectionAddConsoleCommandPass.php:61

感谢您的帮助

如上所述here，它可能是由过时的Composer版本引起的，该版本使用较旧的Symfony控制台组件。因此，当Composer以前加载此类的旧版本时，当您的Symfony实例稍后在cache:clear命令中尝试访问此类时，它不会再次自动加载。

解决方案可能是使用composer self-update更新您的Composer。

我今天遇到了一个类似的问题：我们在项目中使用symfony/console 3.4+，该项目试图通过getDefaultName加载命令名。但是，作曲家内部使用的older version of symfony/console（因为它是added in v3.4.0，因为该方法不存在）。

在这种情况下，composer self-update将无济于事，但是您可以确保将command添加到服务定义中，如下所示：

services:
  myvendorname.mypackagename.foo.command:
    class: MyVendorName\MyPackageName\Command\FooCommand
    tags:
    - { name: 'console.command', command: 'foo' }
#                              ^^^^^^^^^^^^^^^^
#                         This is the important part

这将加载名称directly from the service definition，而不会尝试输入call getDefaultName()。

试图调用名为＆＃34; getDefaultName＆＃34;的未定义方法。
