Symfony 3.0安装

Question

是symfony的新手,从上个月开始,我在终端上使用ubuntu上的以下命令不断安装新的symfony项目

# Linux, Mac OS X
$ symfony new my_project_name

它一直工作到今天,但不仅检查了新版本,但现在它开始给我跟随错误

我甚至在位置usr/local/bin/symfony检查了symfony,它就在那里.

您需要指定要安装的版本,这是一个已解决的问题.如此处和此处所述,您需要:

1. 更新安装程序

   >symfony self-update
   

   或者使用sudo,具体取决于您的安装方式:

   >sudo symfony self-update
   

2. 指定版本:

   >symfony new my_project_name 3.0
   

希望这可以帮助.

UPDATE

使用Symfony安装程序上的错误的正确解决方案,现在3.0是默认版本.在其他情况下,您可以指定完整版本(包括次要版本和主要版本),如下所示:

>symfony new my_project_name 3.0.0
