thinkphp3.2.3 cannot load the database driver: Think\Db\Driver\

Question

This is my code in Common conf config.php

return array(

 //'Configuration item'=>'Configuration value'
 $options = array(
     //Database configuration
     'DB_TYPE' => 'mysql', // Database type
     'DB_HOST' => 'localhost', // Server address
     'DB_NAME' => 'xueji', // database name
     'DB_USER' => 'root', // username
     'DB_PWD' => '', // Password
     'DB_PORT' => '3306', // Port
     'DB_PREFIX' => 'xueji_', // Database table prefix
 ),

);

This is my local database

What's the problem? I keep getting errors and I don't know where the problem is
:(

Everyone, I have solved the problem. Let me tell you. I used C('DB_TYPE') and it was empty. If I look at the above format, the return should be a one-dimensional data and I returned a two-dimensional data
So Change to
return

 //'Configuration item'=>'Configuration value'
 $options = array(
     //Database configuration
     'DB_TYPE' => 'mysql', // Database type
     'DB_HOST' => 'localhost', // Server address
     'DB_NAME' => 'xueji', // database name
     'DB_USER' => 'root', // username
     'DB_PWD' => 'root', // Password
     'DB_PORT' => '3306', // Port
     'DB_PREFIX' => 'xueji_', // Database table prefix

);

That’s it

Answer 1

You are trying it insideCommon目录下的conf目录下的config.php进行数据库的配置的？还是说是在Home(你自己的应用目录)目录下的conf目录下的config.php？
如果是后者，请把数据库的配置更改到Common目录下的conf目录下的config.php

Answer 2

Why doesn’t the questioner post the complete error message? I can’t guess what’s causing this

Answer 3

Try localhost改成127.0.0.1;

If you use Mac, remember to give read and write permissions to all files in the project folder. You can execute it in the project root directory:
sudo chmod -R 777 *
