PHP PDOException无法找到驱动程序

Question

I installed Laravel and cloned a repo from my git server to use on a staging server. After installing all required tools I wanted to migrate the database. The error I now get is:

I installed php-mysql but I don't see why a driver is missing.

Answer 1

I had faced the same issue in my Win 8.1 machine ( 64bit ), i tried almost all possible fixes based on the other answers in stackoverflow. Finally it resolved but i don't know which fix is resolved my issue. I had made the following to fix this issue.

1. Enabled all the pdo extensions in the php.ini file ( still not working )

2. copy and paste the php.ini file as phpForApache.ini in the same directory of my php7 ( still not working )

3. composer uninstalled and again installed with latest php7 as it's php path ( still not working )

4. Closed the command prompt and run the same php artisan migrate query in windows power shell ( Now it works )

Still i don't know which step fix my issue, may b you could try all these steps.
