Php artisan migrate 命令抛出错误

Question

我是 Laravel 的新手，我面临着一个问题。 当我运行 'php migrate artisan' 命令时，它会抛出以下错误：

我查看了几乎所有的引用，我的 .env 和 database.php 文件看起来是正确的，也取消了 php.ini 文件中的 ;extension=php_mssql.dll 的注释，但这些都没有帮助我解决这个问题。

如果有人知道如何解决这个问题，我将不胜感激。

先感谢您

Answer 1

这个原因有很多原因。 其中之一是 php 扩展（如：pdo, ....）。

可能是您使用的 laravel 版本与您在系统中使用的 php 版本不兼容。

例如：您正在使用 laravel 5.5，它需要

• PHP >= 7.0.0
• OpenSSL PHP 扩展
• PDO PHP 扩展
• Mbstring PHP 扩展
• 分词器 PHP 扩展
• XML PHP 扩展

但是您的系统具有 php 5.6 或任何其他更低版本。 哪些没有这些扩展。
