# Linux, Mac OS X 
$ symfony new my_project_name 

安裝在Ubuntu上使用以下命令新的symfony項目，它是完美的工作，直到今天，但比剛纔檢查新版本釋放，但現在它開始給我下面的錯誤

這是一個已解決的問題，您需要指定要安裝的版本。如上所述here和here，您需要：

1. 更新您的安裝

   >symfony self-update 
   

   或使用sudo，這取決於你如何安裝它：

   >sudo symfony self-update 
   

2. 指定的版本：

   >symfony new my_project_name 3.0 
   

希望這會有所幫助。

UPDATE

隨着對Symfony的安裝程序的bug的正確決議，現在3.0是默認版本。在其他情況下，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
