Component Dependency error when installing Modules

Component Dependency error when installing Modules

Magento CE 2.3.3

PHP 7.2

 

When installing modules the Dependency check fails and when i try and run any composer related commands via SSH like composer help etc I get this error message

 

Warning: Unsupported declare 'strict_types' in /home/vendor/magento/inventory-composer-installer/src/Plugin.php on line 6

Parse error: syntax error, unexpected ':', expecting ';' or '{' in /home/vendor/magento/inventory-composer-installer/src/Plugin.php on line 55

 

I have tried changing memory limits and has not helped, googled and tried multiple fixes and nothing seems to work.

Re: Component Dependency error when installing Modules

I'm facing same issue. I'm using PHP 7.3.16 (cli) and Magento CE 2.3.4 There is no solution published on the web. I hope that Magento Forums may help us.

Re: Component Dependency error when installing Modules

I solved this issue by upgrading  System PHP Version to 7.2. If you use CPANEL or WHM on VPS note that System PHP Version may different that PHP Version per Domain.
