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

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：。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：

18{main}遵循以下几点

您的cake php未连接到任何本地数据库，请访问 从浏览器中选择pagesController，查看其是否连接到数据库，如果 不需要在config/app.php中使用数据库名称和 凭证

您在cake php项目目录中，请尝试点击相同的“bin\cake” 烘焙模型用户“在windows中，linux使用”bin/cake烘焙模型 用户”

回复此线程如果问题未解决

在我的案例中，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”

您是否使用composer安装了Cakephp？如果您删除

供应商

目录并执行

composer安装

，问题将得到解决。我刚刚遇到了相同的问题，Linux上的Xampp堆栈中有Cakephp 3.8。原因是运行的PHP版本错误（我在

/usr/bin/PHP

上安装了PHP）。解决方案：在我的路径中添加路径

/opt/lampp/bin

，一切正常。：）
