Codeigniter - An Error Was Encountered - Unable to load the requested class: encrypt
提问by Hrishikesh Choudhari
I have inherited a CI v2.0.2 project.
我继承了一个 CI v2.0.2 项目。
For development purposes, the project was moved to another subdomain, and the database.phpfile has been properly reconfigured.
出于开发目的，项目已移至另一个子域，并且database.php文件已正确重新配置。
The login page loads fine. However, after trying to login, I get an error from CI saying:
登录页面加载正常。但是，在尝试登录后，我收到来自 CI 的错误消息：
An Error Was Encountered
Unable to load the requested class: encrypt
In autoload.php, the databaseand sessionlibraries are autoloaded. This file is the same as in the main codebase.
在 中autoload.php，database和session库是自动加载的。该文件与主代码库中的文件相同。
If I add the encryptlibrary in the above line, I'm unable to see the login page at all.
如果我encrypt在上面的行中添加库，我根本看不到登录页面。
Below is the log file, from loading the login page -

The login works fine when used from the original domain.
从原始域使用时，登录工作正常。
Any pointers where I should begin looking?
我应该从哪里开始寻找任何指示？

Presumably, the error is a result of one of the following reasons.
据推测，该错误是由以下原因之一造成的。
1) Somehow the filename of the library managed to chance causing CodeIgniter to be unable to find the file
1）不知何故，库的文件名设法导致 CodeIgniter 无法找到该文件
2) Perhaps the file doesn't exist on the server and once again, CodeIgniter is unable to find it.
2) 也许该文件在服务器上不存在，再次，CodeIgniter 无法找到它。
3) The filename may be different to that you are referring to in your code.
3) 文件名可能与您在代码中引用的不同。
