CI4开始

Posted 2023-03-18 哆啦啊梦

刚刚下载的CI4框架安装包，配置好apache服务器，第一次运行就开始报错，头大

 经过一番搜索，终于成功解决：

1、将框架模式改为开发模式

E:\\www\\CI-test\\system\\CodeIgniter.php　　打开文件，找到，将“production”改为"development"。

方法一：
/**
     * You can load different configurations depending on your
     * current environment. Setting the environment also influences
     * things like logging and error reporting.
     *
     * This can be set to anything, but default usage is:
     *
     *     development
     *     testing
     *     production
     *
     * @codeCoverageIgnore
     */
    protected function detectEnvironment()
    
        // Make sure ENVIRONMENT isn\'t already set by other means.
        if (! defined(\'ENVIRONMENT\')) 
            define(\'ENVIRONMENT\', env(\'CI_ENVIRONMENT\', \'production\'));
        
    

方法二：
找到E:\\www\\CI-test\\app\\Config\\Boot\\production.php

/*

 |--------------------------------------------------------------------------

 | ERROR DISPLAY

 |--------------------------------------------------------------------------

 | Don\'t show ANY in production environments. Instead, let the system catch

 | it and display a generic error message.

 */

ini_set(\'display_errors\', \'0\');　　//将0改为1，一样可以显示错误信息

error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED & ~E_STRICT & ~E_USER_NOTICE & ~E_USER_DEPRECATED);

　2、刷新页面，会弹出详细错误信息

 

 提示PHP7.4需要安装intl。

接着修改php.ini，将

extension=intl前面的注释去除掉就好。
