cakephp bake SQLSTATE[HY000] [2002]没有这样的文件或目录

Question

我遵循了CakePHP教程，直到现在一切都很好(新添加的文章显示在数据库中)。但是现在我尝试了"bin/cake bake model users“，我得到了下面的错误信息: /opt/lampp/htdocs/MyApp/vendor/cakephp/cakephp/src/Database/Driver.php，第92行没有这样的文件或目录( SQLSTATEHY000 No to file or directory )。我在这里找到了这个解决方案：SQLSTATE HY000 2002 while running bake command。但这似乎不适用于linux(Ubuntu)。任何帮助都将不胜感激。

完全错误：

Answer 1

在我的例子中，这个问题是通过更改app/config.php来修复的，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',...

Answer 2

遵循以下几点

1. 你的蛋糕-php没有连接到任何本地数据库，从浏览器访问pagesController查看它是否连接到了数据库，如果没有，你需要在config/app.php中配置数据库名称和-php项目目录中的用户，尝试在windows中使用相同的"bin\cake bake model users“，对于linux使用"bin/cake bake model users”。
