Php 设置带有火花的codeigniter时出现的问题；活动记录

我在让我的

sparks

安装与我的

codeigniter

安装一起使用时遇到问题

以下是我采取的步骤，具体如下：

RewriteBase /

我通过

PHPCLI

转到

codeigniter

项目文件夹的根目录，使用下面的命令安装sparks

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。这个命令给了我以下文件夹结构

-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

文件夹，其中包含构成

php activerecord

必要组件的

php activerecord

，该命令使用生成一个

MY_Loader.php

文件，如下所示

当我运行codeigniter站点时，我得到以下错误

A PHP Error was encountered

Severity: Notice

我很好奇是什么导致了这个错误？如果我缺少任何其他配置，或者我犯了错误，请告诉我。

您的根

index.php

文件中定义了

EXT

// The PHP file extension
// this global constant is deprecated.
define('EXT', '.php');

---

看看它是否还在那里？

如果常量不在那里，您也可以定义autoload.php而不使用常量。

我知道这是一篇老文章，但希望这能节省一些时间。。。我有同样的问题，上面的修复不起作用。我最终通过删除RewriteBase修复了htaccess文件中的问题，尽管我不确定这首先为什么会导致这个问题

刚才注释了这行，如下所示：

RewriteBase /

到

我替换了$autoload_path=$basepath.config/autoload.EXT；错误消失了，谢谢，但是我仍然在让orm工作时遇到问题。你是对的，但是我会在application/config/constants.php文件中添加这个定义。

#RewriteBase /
