php yii vendor,Yii2的安装--解决无Vendor目录的问题

其实这个问题在后来才知道，是composer默认仓库地址被墙的原因，只需要修composer的默认镜像地址即可，

很多朋友在学习Yii2的时候，都要先从网上下载一个Yii2的源码，但是奇怪的是不论是从Github或是Oschina上面拉下来的代码，无论怎样都看不到Vendor目录，这个问题让我痛苦了好久，但是功夫不负有心人，通过学习和研究终于把这家伙给搞下来了，具体的原因貌似是composer镜像地址的原因，我也不是很清楚，有清楚的可以一起聊聊，下面介绍一下具体的步骤，与大家共勉：

一般来说都是通过Composer来安装，关于Composer的一些基础用法在这里不再啰嗦，网上一搜大把大把的，直接上方法

1.线修改composer的镜像地址(就是把默认的镜像地址修改成国内的)，打开windows的命令行 输入以下代码

composer config -g repo.packagist composer https://packagist.phpcomposer.com

2.就是按照官方的给的下载方法 输入以下命令

composer create-project --prefer-dist --stability=dev yiisoft/yii2-app-advanced yii2

接着就可以看到熟悉而又亲切的显示(如下)
