CakePhp：蛋糕烘焙在Ubuntu上不起作用,(PDOException)

我想在Ubuntu上运行Cake Bake。需要说明的是：

环境、文件系统、数据库和DebugKit都很好，就像CakePhp生成的第一页上提到的那样。
此时“bin/cake bake”显示此消息：

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/php_intl.dll' - /usr/lib/php/20151012/php_intl.dll: cannot open shared object file: No such file or directory in Unknown on line 0
    PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/php_mbstring.dll' - /usr/lib/php/20151012/php_mbstring.dll: cannot open shared object file: No such file or directory in Unknown on line 0

    Welcome to CakePHP v3.4.5 Console

    App : src

    The following commands can be used to generate skeleton code for your application.

    Available bake commands:

    - all
    - behavior
    - cell
    - component
    - controller
    - fixture
    - form
    - helper
    - mailer
    - migration
    - migration_diff
    - migration_snapshot
    - model
    - plugin
    - seed
    - shell
    - shell_helper
    - task
    - template
    - test

    By using `cake bake [name]` you can invoke a specific bake task.

每次我运行'bin/cake bake model questions'或'bin/cake bake all'时，我都会得到以下输出：

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/php_intl.dll' - /usr/lib/php/20151012/php_intl.dll: cannot open shared object file: No such file or directory in Unknown on line 0

当我输入“bin/cake bake controller questions”时，Cake Bake运行。

经过几个小时的努力，我还是没有弄清楚问题出在哪里。我一直在使用蛋糕烘焙的窗口，我从来没有发现这样的困难运行蛋糕烘焙。我真的很感激你能提供的任何帮助。

最后....只需将localhost替换为127.0.0.1

    'default' => [
        'className' => 'Cake\Database\Connection',
        'driver' => 'Cake\Database\Driver\Mysql',

        /**
