SymfonyComponentDependencyInjectionExceptionParameterNotFoundException You have requested a non-existent parameter "server"

  fatal-error, frameworks, orm, php, symfony

I have a serious problem every time I try to execute a command like composer update or php app / console cache: clear throws the following error:

[Symfony  Component  DependencyInjection  Exception  ParameterNotFoundException] You have requested a non-existent parameter "server".

What could be the problem? I have several days in this and I cannot find a solution, the Symfony version is 2.3.
