我什至在usr/local/bin/symfony位置检查了symfony，它就在那里.

I have even check the symfony at location usr/local/bin/symfony and it was there.

推荐答案

这是一个已解决的问题，您需要指定要安装的版本.如此处和

It is a resolved issue that you need to specify the version you want to install. As described here and here, you need to:

1. 更新您的安装程序

1. Update your installer

>symfony self-update

或使用sudo，具体取决于您的安装方式:

or with sudo, depending on how you install it:

>sudo symfony self-update

指定版本:

Specify the version:

>symfony new my_project_name 3.0

希望这会有所帮助.

更新

有了Symfony安装程序上错误的正确解决方案，现在3.0是默认版本.在其他情况下，您可以指定完整的版本(包括次要和主要)，如下所示:

With the correct resolutions of the bug on the Symfony installer, now the 3.0 is the default version. In other case, you can specify the complete version (with minor and major) as follows:

>symfony new my_project_name 3.0.0
