Symfony Demo - unable to sign in

Question

I have upload pushed a Symfony project (based on symfony-demo) to github, however since doing so, I am unable to log in to the demo application as either the demo user or admin - instead I get the the following:

Authentication request could not be processed due to a system problem.

I have tried the below code as the page advises if the users are not working:

php app/console doctrine:fixtures:load

However, when I submit this I get the following error:

  [Doctrine\DBAL\Exception\DriverException]              
  An exception occured in driver: could not find driver  

  [Doctrine\DBAL\Driver\PDOException]  
  could not find driver   

I then tried submitting the following in the hope it would fix the doctrine issue:

composer require doctrine/doctrine-fixtures-bundle

However this fed back the following:

Using version ^2.2 for doctrine/doctrine-fixtures-bundle
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
  Problem 1
    - The requested PHP extension ext-pdo_sqlite * is missing from your system.
  Problem 2
    - sensiolabs/security-checker v2.0.5 requires ext-curl * -> the requested PHP extension curl is missing from your system.
    - sensiolabs/security-checker v2.0.5 requires ext-curl * -> the requested PHP extension curl is missing from your system.
    - sensiolabs/security-checker v2.0.5 requires ext-curl * -> the requested PHP extension curl is missing from your system.
    - Installation request for sensiolabs/security-checker == 2.0.5.0 -> satisfiable by sensiolabs/security-checker[v2.0.5].


Installation failed, reverting ./composer.json to its original content.

Answer 1

Type into your terminal php -m. Do you see curl?

If not, it's not installed. Depending on your distro you might do:

RHEL/Centos:

yum install php5_curl

Ubuntu/Debian:

apt-get install php5_curl

If not found, try one of the following: php_curl, php-curl, php5_curl or php5-curl. Less frequently there is 56 instead of 5. You could simplify by searching for curl and then looking over the list.

Not sure about other distros, but it should be similar.
