我在所有文件(js,css,php,...)中添加了许可文本,但是在尝试在.html.twig文件中添加文本时遇到了麻烦.我试过以下代码:

{% extends 'MSDHomeBundle::base.html.twig' %}
{% block javascripts %}
...

我收到这个错误:

A template that extends another one cannot have a body in MSDHomeBundle:Home:index.html.twig at line 2. 

我之后也试过添加它{% extends 'MSDHomeBundle::base.html.twig' %},但是我得到了同样的错误.

怎么解决它的想法？

您可以将许可证/作者信息添加到twig文件,如下所示:

{#

#}

{% extends 'MSDHomeBundle::base.html.twig' %}
