Symfony 3.0 安装

php symfony

2022-08-30 22:11:45

我是symfony的新手，从上个月开始，我不断在终端上使用ubuntu上的以下命令安装新的symfony项目

# Linux, Mac OS X
$ symfony new my_project_name

直到今天，它一直完美运行，但不仅仅是检查新版本发布，但现在它开始给我以下错误

我甚至在位置usr/local/bin/symfony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。如此处和此处所述，您需要：

更新安装程序
```
>symfony self-update
```
或使用 sudo，具体取决于您的安装方式：
```
>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安装程序上错误的正确分辨率，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
