参考：https://github.com/yiisoft/yii2-app-advanced/blob/master/docs/guide-zh-CN/start-installation.md
先composer来个命令：composer create-project --prefer-dist yiisoft/yii2-app-advanced yii-application
然后配置服务器的域名啥的，然后init.bat，然后
composer config repo.packagist composer https://packagist.phpcomposer.com修改composer的配置，底部
"repositories": {
"packagist": {
"type": "composer",
"url": "https://packagist.phpcomposer.com"
}
}然后进入composer.json的根目录执行composer update（好了的项目不要轻易这个操作），ok了
