Question

我是Laravel的新手，我面临一个问题。当我运行“ php migration artisan”命令时，它将引发以下错误：

我查看了几乎所有引用，我的.env和database.php文件看起来似乎正确，也取消了php.ini文件中的; extension = php_mssql.dll的注释，但这无助于我解决此问题。

如果有人知道如何解决这个问题，我将不胜感激。

谢谢您

我的.env文件：

我的database.php文件：

此原因有很多原因。其中之一是php扩展名（例如：pdo，...）。

可能是您使用的laravel版本与您系统中使用的php版本不兼容。

例如：您正在使用需要

的laravel 5.5

PHP> = 7.0.0
OpenSSL PHP扩展
PDO PHP扩展
Mbstring PHP扩展
Tokenizer PHP扩展
XML PHP扩展

但是您的系统具有php 5.6或更低的版本。没有这些扩展名。
