最佳答案

You might need to comment out the following in your php.ini file.

;extension=pdo_mysql.so

Taken from this post: Laravel 5 PDOException Could Not Find Driver . I think I had to do something exactly like this when setting up laravel on digital ocean.

Finally I fixed this. There was a typo in the server configuration and all paths to php extecutables were fine except the path to php-cli, which caused the error. When I fixed the path, everything worked fine.

Your database driver is missing. To solve the probelm

First install the driver

For ubuntu: For mysql database.

sudo apt-get install php5.6-mysql/php7.2-mysql

You also can search for other database systems.

You also can search for the driver:

sudo apt-cache search drivername

Then Run the cmd php artisan migrate

小开

First check php -m
.If you don't see mysql driver install mysql sudo apt-cache search php-mysql
Your results will be similar to:

php-mysql - MySQL module for PHP [default]

install php- mysql Driver

sudo apt-get install php7.1-mysql

I got the same error when running my test suite. It was working before but it stopped working after I upgraded php. So I did

sudo apt-get install php-sqlite3

and it worked.

小开

In window OS. I have uncomment extension=pdo_mysql for php.ini file that locate at same directory of php.exe. after that it work fine.

小开

In CentOS7，I try this: yum install php-mysql, then edit php.ini

小开

Even simpler in Ubuntu (18.04)

apt install php-mysql

Done. No need to edit any .ini files.

Happy coding!

小开

I had the same issue, and I uncomment extension=pdo_sqlite and ran the migration and everything worked fine.

小开

You are probably missing sqlite or the specific DB driver you are trying to migrate.

Install the DB driver and you'd be fine. You don't necessarily need to edit your php.ini file (it's one way to fix it too though).

For sqlite do --> sudo apt-get install php-sqlite3 Then php artisan migrate

NB: I assume you have PHP and MySql already installed

Solution 1:

1. php -v

Output: PHP 7.3.11-1+ubuntu16.04.1+deb.sury.org+1 (cli)

2. sudo apt-get install php7.3-mysql

Solution 2:

Check your DB credentials like DB Name, DB User, DB Password

小开

if you have installed new version of php 7.2+ then you have to uncomment this line in php.ini ;extension=pdo_mysql

小开

In my case I'm using Ubuntu so I found that my system is not installed php-sqlite3, after installation its got fixed.

sudo apt-get install php7.2-sqlite3

小开

I had a similar issue in Ubuntu 16.04 and what help me was that i installed php-mysql for php 7.2. I would recommend you run the following command if you have php 7.2 or install php mysql depending on your version of PHP. Make sure that you have installed the DBAL packege

apt-get install php7.2-mysql


systemctl restart apache2

小开

I faced the same problem while using sqlite 3:

Make sure the changes made on .env.example and the same on the .env file.
Then run $ sudo apt-get install php-sqlite3 on terminal.
Finally $ php artisan migrate.

小开

In case that you run test in sqlite run

sudo apt install sqlite3 && sudo apt install php-sqlite3

If you run test in window, you dont need install nothing. Only config your phpunit.xml

小开

In Linux Download Mysql and Php

sudo apt install php-mysql

Then the problem will be solved.

Some Additional information for people who upgraded their php version.

This is for laravel framework using MySql or MariaDB.

I had issues after upgrading php version from 7.2 to 7.4.

Make sure you completely install php extentions and packages for php version 7.4 (Or your installed php version).
Make sure you enable these extentions. pdo_mysql, xmlrpc, mbstring, mysqli, openssl, fileinfo, gd2, curl at php.ini.
Then clear cache, config
Restart all services such as apache, supervisor

ERROR: could not find driver (SQL: select * from tests where slug = a limit 1)

I was getting the above error in my laravel project, i am using nginx server on ubuntu 16.04

This error is because, php-mysql driver is missing. To install it type following command.

sudo apt-get install php7.2-mysql

Please specify your current php version in above command.

Open php.ini file and uncomment the followling line of code(Remove Semicolon).

;extension=pdo_mysql

Then Restart the nginx and php service

sudo systemctl restart php7.2-fpm
sudo systemctl restart nginx

It worked for me.

小开

You need to enable these extensions in the php.ini file

Before:

;extension=pdo_mysql
;extension=mysqli
;extension=pdo_sqlite
;extension=sqlite3

After:

extension=pdo_mysql
extension=mysqli
extension=pdo_sqlite
extension=sqlite3

It is advisable that you also activate the fileinfo extension, many packages require this.

小开

For me, php.ini was OK, but I needed to restart php artisan serve.

小开

in ubuntu or windows

path php.ini
php -i
Remove the ; from ;extension=pdo_mysql or extension=php_pdo_mysql.dll and add extension=pdo_mysql.so

restart xampp or wampp
install sudo apt-get install php-mysql

and

php artisan migrate

小开

For me, these steps worked in Ubuntu with PHP 7.3:

1. vi /etc/php/7.3/apache2/php.ini > uncomment:
;extension=pdo_sqlite
;extension=pdo_mysql
2. sudo apt-get install php7.3-sqlite3
3. sudo service apache2 restart

小开

On Windows, I followed the same path as the previous answers. The difference is that the path to php.ini is usually different from the traditional ones, usually in Apache.

To find php.ini, I used the following path: C:\tools\php80\php.ini

After that, I uncommented the pdo extension files and the migration worked.

For sqlite on debian/ubuntu

PHP 7.1

sudo apt install php7.1-sqlite3

PHP 7.2

sudo apt install php7.2-sqlite3

PHP 7.3

sudo apt install php7.3-sqlite3

PHP 7.4

sudo apt install php7.4-sqlite3

小开

for Windows 8.1/10 in :\php.ini file you should uncomment line "extension=pdo_mysql"

小开

In my case I the php path was different from xampp php path that my project hosted on.

So I just change the system path from the pure php path to the php path in xamppp and all working fine.

I run this command in Ubuntu

sudo ln -s /opt/lampp/bin/php /usr/bin/php

may you have installed the php so like me you need to first run this command and then try above again

sudo rm /usr/bin/php

May your composer has some issue so you need to run this as well

curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/bin --filename=composer

For php 8 running on laravel 8 (ubuntu), run sudo apt install php8.0.3-mysql then restart apache sudo service apache2 restart

This error happened to me using sail for development. In this case the solution was to run the command inside the container

docker exec -it <app-container-id> php artisan migrate

The app container id is probably like this:

<app-name>_laravel.test_1

小开

Not really answer to original question but might help to someone:

When using docker you have to execute:

docker-compose exec [NAME_OF_DOCKER_SERVICE] php artisan migrate

Instead of only php artisan migrate

Just wanted to share this as I have made this error few times already

Create a .env file.

if using laravel and composer, generate a key for project.

php artisan key:generate
