How to solve Twig_Error_Runtime in Symfony 3 - symfony

Question

I have inherited a rather complicated Symfony 3 project (I'm using Laravel mostly nowadays - it's been years since I used Symfony) so this is a bit out of my wheelhouse.
I did a composer update and it built ok.
composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
Package operations: 0 installs, 1 update, 0 removals
- Updating twig/twig 1.x-dev (e8555dc => 1445246): Checking out 1445246d8e
Writing lock file
Generating autoload files
> Incenteev\ParameterHandler\ScriptHandler::buildParameters
Updating the "app/config/parameters.yml" file
> Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::buildBootstrap
> Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache
// Clearing the cache for the dev environment with debug
// true
[OK] Cache for the "dev" environment (debug=true) was successfully cleared.
> Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::installAssets
Trying to install assets as relative symbolic links.
-- -------- ----------------
Bundle Method / Error
-- -------- ----------------
[OK] All assets were successfully installed.
> Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::installRequirementsFile
> Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::prepareDeploymentTarget
I cleared the cache
php bin/console cache:clear --no-warmup --env local
When I browse to my local development URL, I get:
Whoops, looks like something went wrong.

Since this appears to be an issue with vendor files, I'm not sure where to go from here.

Answer 1

Try to add this line in composer.json
"twig/twig": "2.4.4"
For me worked.
It seems the last updates for twig 2.4.5 had this problem.
I found the answer here:
