I'm getting constant errors as the below message but I'm not sure where to start by fixing this issue:

[2016-12-15 02:35:01] setup-cron.ERROR: Could not locate magento/magento2-base/composer.json file.

  • Run first compose update & php bin/magento setup:upgrade, then try again on Magento Root Folder

It happened the same for me when Magento 2 was cloned from the git repository. As the documentation mentions, in such case you should run only one cron job, the

* * * * * /usr/bin/php /var/www/magento2/bin/magento cron:run | grep -v "Ran jobs by schedule" >> /var/www/magento2/var/log/magento.cron.log

because the other two are for those who installed Magento from the downloadable package.


Known issue, it has been discussed on github.
