多域名多服务器回调系统安装问题

Q：访问域名时出现如下错误：

Warning: require(/www/wwwroot/back.juyun.top/public/../vendor/autoload.php): failed to open stream: No such file or directory in /www/wwwroot/back.juyun.top/public/index.php on line 15

Fatal error: require(): Failed opening required '/www/wwwroot/back.juyun.top/public/../vendor/autoload.php' (include_path='.:') in /www/wwwroot/back.juyun.top/public/index.php on line 15

A：解决方法：

第一步：进入网站根目录，然后点击终端。

第二步：在终端窗口运行下面的命令：

composer install

第三步：出现如下界面，则表示composer安装完成，再次访问域名安装。
