我的http_proxy / https_proxy已经定义,我的DNS也是.除非,用于下载安装程序的命令sudo curl -LsS https://symfony.com/installer -o /usr/local / bin / symfony无法正常工作.

现在,我想创建一个新项目,所以在我的项目文件夹中输入symfony new project.如果我指定symfony新项目2.8或symfony新项目3.0同样的事情.

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>]

如果我做PHPinfo(),我会打开：

openssl
OpenSSL support     enabled
OpenSSL Library Version     OpenSSL 1.0.1k 8 Jan 2015
OpenSSL Header Version  OpenSSL 1.0.1k 8 Jan 2015
Openssl default config  /usr/lib/ssl/openssl.cnf

我的PHP版本,如果我做一个PHP -v：

PHP 5.6.17-0+deb8u1 (cli) (built: Jan 13 2016 09:10:12)
Copyright (c) 1997-2015 The PHP Group
Zend Engine v2.6.0,Copyright (c) 1998-2015 Zend Technologies
    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以及如何修复它时,为什么会出现错误？是PHP版本吗？我需要Linux包或其他PHP扩展吗？在某处配置还有什么吗？
