100- code doesn't work for some services. For instance, if you try to get the ``request ``

123- If you dig into the Translator component classes, you'll see that the ``request ``

127- public function getLocale()
128- {

137- Therefore, when using the ``translator `` service inside a command, you'll get the
138- previous *"You cannot create a service of an inactive scope" * error message.
139- The solution in this case is as easy as setting the locale value explicitly
140- before translating contents::
141-
142- protected function execute(InputInterface $input, OutputInterface $output)
143- {
144- $name = $input->getArgument('name');
145- $locale = $input->getArgument('locale');
146-
147- $translator = $this->getContainer()->get('translator');
