-1.  如果安装后打开页面提示404错误，请检查服务器伪静态配置，宝塔伪静态请配置使用thinkphp规则
-2.  如果提示当前权限不足，无法写入配置文件config/database.php，请检查database.php是否可读，还有可能是当前安装程序无法访问父目录，请检查PHP的open_basedir配置
-3.  如果composer install失败，请尝试在命令行进行切换配置到国内源，命令如下composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

+1.  安装失败，可能存在php配置文件禁止了putenv 和 proc_open函数。解决方法，查找php.ini文件位置，打开php.ini，搜索 disable_functions 项，看是否禁用了putenv 和 proc_open函数。如果在禁用列表里，移除putenv proc_open然后退出，重启php即可。
