You need to set your "document root" to the public folder inside your project. This could be your default setting, or that of a virtual host, depending on how you set up your local development environment. ```  修改文件 `E:\xampp\apache\conf\httpd.conf` ，第247行。（我的xampp解压在`E:\` ， 注意先备份，再修改！） ``` # # DocumentRoot: The directory out of which you will serve your # documents. By default, all requests are taken from this directory, but # symbolic links and aliases may be used to point to other locations. # DocumentRoot "/xampp/htdocs" <Directory "/xampp/htdocs"> ``` 改为： ``` DocumentRoot "/xampp/htdocs/public" ``` 修改完毕后，重启Apache，然后访问：127.0.0.1 。  ## 2.修改Codeigniter的App.php 打开 `e:\xampp\htdocs\application\Config\App.php` 文件，24行： ``` public $baseURL = ''; ``` 改为： ``` public $baseURL = 'http://127.0.0.1/'; ```
