【问题讨论】：

请不要向我们展示代码图片。将代码作为文本粘贴到您的问题中 @RiggsFolly 好的，请查看错误日志。这有帮助吗***.com/questions/20723803/… @RiggsFolly nope 为什么不呢？你没看懂答案吗？还是您已经尝试过的解决方案？ 【参考方案1】：

最常见的解决方案是在 .env 文件中将 localhost 更改为 127.0.0.1

PDOException SQLSTATE[HY000] [2002] No such file or directory

"SQLSTATE[HY000] [2002] No such file or directory" error when migrating table in Laravel

【讨论】：

.env 文件中没有 127.0.0.1 彼得！解决方案是将localhost 更改为127.0.0.1 所以你在任何地方看到LOCALHOST !!!!!! Errrr，有趣的是，我可以在您的 .env 文件中看到 127.0.0.1 ？？？？这不是我们所说的参数，但它足够正确亲爱的@RiggsFolly 如果我将 REDIS_HOST=127.0.0.1 更改为 REDIS_HOST=localhost 彼得请注意！！！我已经说过这不是要更改的参数【参考方案2】：

确保你的 .env:

SESSION_DRIVER=file
