PHP PDOException 找不到驱动程序

Question

我安装了 Laravel 并从 git 服务器克隆了一个存储库以在临时服务器上使用。安装所有必需的工具后，我想迁移数据库。我现在得到的错误是:

我安装了 php-mysql，但我不明白为什么缺少驱动程序。

Answer 1

我在我的Win 8.1机器(64位)中遇到了同样的问题，我根据stackoverflow中的其他答案尝试了几乎所有可能的修复。最后它解决了，但我不知道哪个修复解决了我的问题。我已采取以下措施来解决此问题。

1. 启用了 php.ini 文件中的所有 pdo 扩展(仍然不起作用)

2. 将 php.ini 文件作为 phpForApache.ini 复制并粘贴到我的 php7 的同一目录中(仍然无法正常工作)

3. composer 已卸载，并再次安装了最新的 php7，因为它是 php 路径(仍然无法正常工作)

4. 关闭命令提示符并在 Windows Power shell 中运行相同的 php artisan migrate 查询(现在可以运行了)

我仍然不知道哪个步骤可以解决我的问题，也许您可​​以尝试所有这些步骤。
