Cannot install using composer

[krstns]

I've tried running the composer install today with the following result:

composer require omines/datatables-bundle
Do not run Composer as root/super user! See https://getcomposer.org/root for details
Using version ^0.3.1 for omines/datatables-bundle
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Restricting packages listed in "symfony/symfony" to "4.4.*"

  [ErrorException]
  Undefined index: extra

I've tried searching for solutions, found some similar issues with other projects but non of the possible fixes could be applied (I am not using packagist).

@krstns try run it with -vvv and see stack trace. It might not be the cause of package you try to install but the one you already have.

Quick solution/workaround is to remove this restriction to 4.4.* from your composer.json ( somewhere at the end of it)

@krewetka thanks a lot for taking interest. i've used composer for a while but never had to debug it.

These are the last bits of the log and the stacktrace.

So I took your advice and removed the bit regarding 4.4.* restriction. Afterwards the installation went on but failed due to lack of memory.

So I've tried to increase it by running:

php -d memory_limit=-1 /opt/bitnami/php/bin/composer.phar -vvv require omines/datatables-bundle

I guess the issue now is the memory on my docker container. Will try to increase the limit.

[krewetka]

So it is definitely flex problem. Problem with out of memory is quite known one for composer, that is why this restriction to selected symfony version was introduced.

As a quick workaround you can do fix this line in Cache.php. In newest version https://github.com/symfony/flex/blob/master/src/Cache.php you can see that this is check if extra is existing.

After quick workaround you should be able to upgrade at least flex to newer version ( so workaround is not needed).

Not a bundle issue.
