  2. Import products from Magento 1.7.x store.
  3. In Magento backend, set indexes to update on schedule.
  4. Run php bin/magento indexer:reindex.

  • What does which php print? Mar 18 '16 at 15:48
  • /usr/local/bin/php Mar 18 '16 at 16:05
  • Maybe there's something wrong with that php. Find out what your webserver is using, and use that in the command line. Mar 18 '16 at 16:06
  • both are using php 7.0.4. Mar 18 '16 at 16:19

In the end I found that my cli was using a different path to php than apache. I am using cpanel, so the cli was pointing to /opt/cpanel/ea-php70/. After running yum install ea-php70-php-{magento dependency} (i.e. yum install ea-php70-php-bcmath, etc.) for all of the magento dependencies, I am able to use the cli without any errors. Hope this helps someone else.


I'm adding my answer because I had same issue after uploading new module and running php bin/magento upgrade

after this I had simmillar error couldn't clean cache and run reindex.

I input again php bin/magento upgrade (only command that works)

and I found that I had bad configuration in xml file

Element 'global': No matching global declaration available for the validation root.  
  Line: 2 

after I fix that issue I run again php bin/magento upgrade and all command works now.
