Symfony的3.2：树枝/树枝V2.0.0需要PHP^7.0

我只是想用PHP 5.6的服务器上安装我的Symfony 3.2的应用程序，并且composer install告诉我twig/twig v2.0.0 requires php ^7.0 -> your PHP version (5.6.22) does not satisfy that requirement.Symfony的3.2：树枝/树枝V2.0.0需要PHP^7.0

我怎样才能改变树枝版本在我的应用程序中使用？据我所知，Symfony使用树枝束（https://packagist.org/packages/symfony/twig-bundle）。

我是否需要在较低版本（哪一个？）中添加symfony/twig-bundle，或者是否需要将我的composer.json require部分添加到twig/twig v1.31.0？

UPDATE：

我composer.json：

你可以在这里发布你的'composer.json'文件吗？ –

@TomaszMadeyski我做了:) – meandeveloper111

你可以用嫩枝1.x的:.添加/在你composer.json更改此：

"require": { 
    "symfony/symfony": "v3.2.*", 
    "twig/twig": "1.31.*" 
}

然后运行composer update。如果你想知道install和update之间的区别是什么，请阅读this answer。

感谢您的回答斯蒂芬。我添加了捆绑包，但是使用作曲家安装它仍然尝试安装v2.0.0。也许我需要以某种方式更新composer.lock？我会发布我的composer.json和命令的结果作为我的问题的更新。 – meandeveloper111

'composer.json'发生变化后，您需要运行'composer update'（而不是''install'） –

啊，当然！谢谢你，你的回答解决了我的问题:) – meandeveloper111
