我在使用sparks安装
codeigniter安装时遇到问题
以下是我采取的步骤如下：
我通过我的codeigniter访问了我的PHPCLI项目文件夹的根目录，使用以下命令安装了火花
php -r "$(curl -fsSL http://getsparks.org/go-sparks)"
我使用下面的spark命令安装了活动记录库
php tools\spark install -v0.0.2 php-activerecord
2a上。这个命令给了我下面的文件夹结构
-application
-sparks
-php-activerecord
-0.0.2
-config
-variables
-vendor
-system
-tests
-tools
-lib
-spark
-sparktypes
-test
-user_guide
2B。此命令生成一个sparks包含php active record文件夹，构成php-activerecord的必要组件，使用该命令生成MY_Loader.php文件，如下所示
<?php if (! defined('BASEPATH')) exit('No direct script access allowed');

我修改我的autoload.php以包含php活动记录，如下所示
$autoload['sparks'] = array('php-activerecord/0.0.2');
当我运行我的codeigniter网站时，我收到以下错误
A PHP Error was encountered
Severity: Notice
Message: Use of undefined constant EXT - assumed 'EXT'

我很好奇可能导致此错误的原因是什么？如果我缺少任何其他配置或者我犯了错误，请告诉我。
答案 0 :(得分：16)
EXT在您的根index.php文件中定义。
// The PHP file extension
// this global constant is deprecated.
define('EXT', '.php');
看看它是否仍然存在？
答案 1 :(得分：0)
如果没有常量，你也可以在不使用常量的情况下定义autoload.php。
答案 2 :(得分：0)
我知道这是一个旧帖子，但希望这会节省一些时间...我有同样的问题，上面的修复不起作用。我最后通过删除RewriteBase修复了htaccess文件中的问题，虽然我不知道为什么这会导致问题出现。
刚刚将该行注释如下：
RewriteBase /
到
#RewriteBase /
