我正在尝试学习Symfony。所以我从 symfony.com 下载了安装程序。
我的http_proxy/https_proxy被定义，我的DNS也被定义。除非sudo curl -LsS https://symfony.com/installer -o /usr/local/bin/symfony用于下载安装程序的命令无法正常工作。
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，也是如此.
结果是一条错误消息：
Downloading Symfony...

如果我做一个phpinfo()，我已经打开了：
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
如果我做一个php -v我的PHP版本：
PHP 5.6.17-0+deb8u1 (cli) (built: Jan 13 2016 09:10:12)

Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies

我的问题：为什么当我尝试创建新项目时会出现错误以及如何修复它？是由于PHP版本吗？我需要 Linux 软件包或其他 PHP 扩展吗？还有什么要配置的吗？

好吧，昨天我在这一点上被封锁了半天。这就是为什么我决定在StackOverflow上询问...最后我找到了答案...
git-hub Symfony-installer 问题
我必须安装php5-curl.
apt-get install php5-curl
希望它至少可以帮助将来的某人。
