Php Symfony 3.0安装

我是symfony的新手，从上个月开始，我一直在使用以下命令从终端在ubuntu上安装新的symfony项目

# Linux, Mac OS X
$ symfony new my_project_name

直到今天，它都工作得很好，但不仅仅是检查了新版本的发布，但现在它开始给我以下错误

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

这是一个已解决的问题，您需要指定要安装的版本。如前所述，您需要：

更新你的安装程序

>symfony self-update

或者使用sudo，具体取决于安装方式：

>sudo symfony self-update

指定版本：

>symfony new my_project_name 3.0

希望这有帮助

更新

有了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，您可以按如下方式指定完整版本（包括次要版本和主要版本）：

>symfony new my_project_name 3.0.0
