Symfony的3.0安装

Question

# Linux, Mac OS X 
$ symfony new my_project_name 

安装在Ubuntu上使用以下命令新的symfony项目，它是完美的工作，直到今天，但比刚才检查新版本释放，但现在它开始给我下面的错误

我连查的位置USR/local/bin目录/ symfony中的Symfony和它在那里。

Answer 1

这是一个已解决的问题，您需要指定要安装的版本。如上所述here和here，您需要：

1. 更新您的安装

   >symfony self-update 
   

   或使用sudo，这取决于你如何安装它：

   >sudo symfony self-update 
   

2. 指定的版本：

   >symfony new my_project_name 3.0 
   

希望这会有所帮助。

UPDATE

随着对Symfony的安装程序的bug的正确决议，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
