Method 1:
方法一：
Please access the file
请访问文件
System >> Core >> Codeigniter.php
系统 >> 核心 >> Codeigniter.php
/**
* CodeIgniter Version
*
* @var string
*
*/
define('CI_VERSION', '3.0.0');
Method 2:In index.php or any other view file write the following code of php as follows:
方法二：在 index.php 或其他视图文件中写入如下 php 代码：
<?php
echo CI_VERSION;
?>
CI_VERSION is build in constant in codeigniter, which contains value of version.
CI_VERSION 是内置于 codeigniter 中的常量，其中包含 version 的值。
Thank you!
谢谢！

Which means you are not properly configure your codeigniter project / system folder. System folder is not necessary to be placed in project root. you can place anywhere and configure the correct system path[something like $system_path = '../system';] in the index.php(project root) properly. It should work...
这意味着您没有正确配置您的 codeigniter 项目/系统文件夹。不需要将系统文件夹放在项目根目录中。您可以放置在任何地方并$system_path = '../system';在 index.php（项目根目录）中正确配置正确的系统路径[类似的东西]。它应该工作...
