[FIXED] Database Exception – yii\db\Exception : could not find driver

Issue

I am working on Centos in Yii2. I have upgraded php 5.4 to php 7.1.19 but after upgrading it is showing me the error:

Database Exception – yii\db\Exception could not find driver Caused by: PDOException could not find driver

I have added config files in /etc/php.d and /usr/lib64/php/modules but it still gives me the same error. I have checked using php -me the extension for pgsql is not available.

Any suggestion would be a great help. Thank you.

Solution

It was an issue with the installation files. Installing the following command did the job: yum install php-pgsql
