您已请求不存在的服务“Doctrine”。 你的意思是：“学说”？

Question

After upgrade symfony 2.8 to 3.4 each time i run

php bin/console debug:contaier

I get :

In Container.php line 348:

  You have requested a non-existent service "Doctrine". Did you mean this: "doctrine"?                                                                    

Project worked perfectly with symfony 2.8. How can I fix this dummy error?

Answer 1

Please take a look to this blog post. It means that from 2.8 to 3.4 a symfony DI container became case sensitive.

$this->get('Doctrine');

Is no longer equivalent to

$this->get('doctrine');

So you should look at all config files, controllers and other services that use doctrine and check that they are using the doctrine not the Doctrine.
