Error when reindexing

Question

when I use php bin/magento indexer:reindex or php bin/magento cron:run I keep getting this error.

Parse error: syntax error, unexpected '?', expecting variable (T_VARIABLE) in /home/[NAME]/public_html/vendor/magento/framework/Filesystem/Directory/Write.php on line 35

I'm using php 7.2 and Magento 2.3

Any ideas of how to fix this?

Answer 1

Ok so I doubled check and my PHP was 7.2 no problem with that. Now the way I was able to fix it was to run this code:

[-/public_html]#/usr/local/php72/bin/php-cli bin/magento indexer:reindex

instead of:

php bin/magento indexer:reindex

to directly execute the command via the php-cli binary. Same for the other commands such as:

bin/magento setup:update

seems to be working fine right now. But I don't know the reason I was getting that error.

Answer 2

Make a dummy php file and put in it. Look for the PHP version and make sure 7.2 is really there. Because this kind of error might occur with incompatible PHP version.
