Php Symfony:找不到套接字传输“；http「；

我正在努力学习Symfony。所以我已经从下载了安装程序

我的

http\u代理

/

https\u代理

已定义，我的DNS也已定义。除非，否则命令

sudo curl-LsShttps://symfony.com/installer -用于下载安装程序的o/usr/local/bin/symfony

无法工作

现在，我想创建一个新项目，因此在我的项目文件夹中键入

symfony new project

。如果我指定

symfony new project 2.8

或

symfony new project 3.0

，情况也是如此

结果是一条错误消息：

 Downloading Symfony...

  [GuzzleHttp\Exception\RequestException]
  Error creating resource: [message] fopen(http://symfony.com/download?v=Symfony_Standard_Vendors_latest.tgz): failed to open stream: Unable to find the socket transport "http" -

new <directory> [<version>]

如果我执行

PHP-v

，我的PHP版本是：

PHP 5.6.17-0+deb8u1 (cli) (built: Jan 13 2016 09:10:12)

    with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2015, by Zend Technologies

我的问题：当我尝试创建一个新项目时，为什么会出现错误，以及如何修复它？是因为PHP版本吗？我需要linux软件包还是其他PHP扩展？还有什么地方需要配置吗？

Arf-\uu-'

好的，我昨天在这一点上被封锁了半天。这就是我决定询问StackOverflow的原因。。。最后我找到了答案

我必须安装

php5 curl

apt get install php5 curl

希望它将来至少能帮助别人。

谢谢。它起作用了。我在代理服务器后面使用laravel。
