This is localized exception error along with module version upgrade error.

So open your terminal from your root directory of magento2 and run below commands in sequence.

1) php bin/magento setup:upgrade
2) php bin/magento setup:di:compile
3) php bin/magento setup:static-content:deploy
4) php bin/magento indexer:reindex
5) php bin/magento cache:clean
6) php bin/magento cache:flush
