【中文标题】cakephp bake SQLSTATE[HY000] [2002] 没有这样的文件或目录

【英文标题】：cakephp bake SQLSTATE[HY000] [2002] No such file or directory

【发布时间】：2019-05-08 02:32:49

【问题描述】：

我遵循 Cakephp 教程，到目前为止一切正常（新添加的文章显示在数据库中）。但是现在我尝试“bin/cake bake model users”我收到以下错误消息： SQLSTATE[HY000] [2002] No such file or directory in [/opt/lampp/htdocs/MyApp/vendor/cakephp/cakephp/ src/Database/Driver.php，第 92 行]。 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）。任何帮助将不胜感激。

完全错误：

【问题讨论】：

你用 composer 安装 Cakephp 了吗？

看来如果您删除vendor 目录并执行composer install 问题将得到解决

我刚刚遇到了同样的问题，Linux 上的 Xampp 堆栈中的 CakePHP 3.8。原因是运行的 PHP 版本错误（我在系统范围内安装的 PHP 在/usr/bin/php）。解决方案：将路径 /opt/lampp/bin 添加到我的 PATH 中，一切都很好。 :)

【参考方案1】：

遵循以下几点

您的 cake-php 未连接到任何本地数据库，请访问 pagesController 从浏览器查看它是否连接到数据库，如果 不需要在 config/app.php 中配置数据库名称和 凭据。 你在 cake-php 项目目录下，尝试点击相同的“bin\cake 烘焙模型用户”在 Windows 中，对于 linux 使用“bin/cake bake model 用户”。

如果问题未解决，请回复此主题

【参考方案2】：

在我的情况下，通过更改 app/config.php 解决了问题，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',...
