Symfony 4 - 不渲染树枝模板

Question

When trying to render a Twig Template within a Symfony 4 project I'm getting an error. I don't know which is the problem. This is the code generating the error:

return $this->render('templates/imagenes/index.html.twig');

And this is the error I'm getting:

LogicException You can not use the "render" method if the Templating Component or the Twig Bundle are not available.

Should I install Twig via composer apart Symfony itself?

Answer 1

谢谢@gogaz安装树枝做了伎俩。

composer require twig

Answer 2

你不应该需要模板目录，所以只需'imagenes / index.html.twig'

Answer 3

 return $this->render('templates/imagenes/index.html.twig');

Create the project using this command

composer create-project symfony/skeleton-website project_name

No need to install twig,etc

Answer 4

A guy named Simon Wald-burger mentioned in the lesson's comments that installing "debug" fixed the issue (it fixed it for me). The instruction was in the next lesson.

composer require debug --dev

iiirxs is also correct, to output dump in twig file, do

{{ dump(variable) }}
