解决方案>

我有同样的问题，发现这只是一个更改设置的问题：

修改您的database.php配置文件，并将pconnect假。作为CI 3框架的一部分，它将是此数组的一部分：

  $ db ['default'] = array 
'pconnect'=> FALSE //此值
）; 
  

或者如果您的配置文件看起来更像CI 2版本：

  $ db ['default'] ['pconnect'] = FALSE; 
  

一点搜索似乎暗示数据库不喜欢持久连接，可能是因为安全原因。

Codeigniter 2 to 3 version after upgrading, I get this error.. Why would that be?

An uncaught Exception was encountered

解决方案

I had the same issue, and found that it was just a matter of changing a setting:

Modify your database.php config file and turn 'pconnect' to false. As part of the CI 3 Framework, it would be part of this array:

$db['default'] = array(
    'pconnect' => FALSE // This value
);

Or if your config file looks more like the CI 2 version:

$db['default']['pconnect'] = FALSE;

A bit of searching seems to suggest that the database doesn't like a persistent connection, possible because of security reasons.
