Cakephp烘焙SQLSTATE[HY000][2002]没有这样的文件或目录

Question

我遵循了CakePHP教程，到目前为止一切都很好（新添加的文章显示在db中）。但现在我尝试“bin/cake bake model users”，我得到了以下错误消息：SQLSTATE[HY000][2002]在[/opt/lampp/htdocs/MyApp/vendor/cakephp/cakephp/src/Database/Driver.php，第92行]中没有这样的文件或目录。我在这里找到了这个解决方案：sqlstatehy0002002，同时运行bake命令。但这在linux（Ubuntu）上似乎不起作用。任何帮助都将不胜感激。

完全错误：

Answer 1

遵循以下几点

1. 您的cake php未连接到任何本地数据库，请从浏览器访问pagesController以查看其是否连接到数据库，如果未连接，则需要在config/app中进行配置。带有数据库名称和凭证的php
2. 您在cake php项目目录中，尝试在windows中点击相同的“bin\cake bake model users”，对于linux，使用“bin/cake bake model users”

如果问题未解决，请回复此线程

Answer 2

在我的案例中，通过更改app/config解决了这个问题。php，只需将数据源主机从“localhost”更改为“127.0.0.1”

    'Datasources' => [
    'default' => [
        'className' => 'Cake\Database\Connection',
        'driver' => 'Cake\Database\Driver\Mysql',
        'persistent' => false,
        'host' => '127.0.0.1',...
