I am working on a Drupal 8 site. This site was working. I recently moved to another machine.

It is showing errors like: 

Recoverable fatal error: Argument 1 passed to 

Drupal\Component\DependencyInjection\Container::__construct() must be of

 the type array, boolean given, called in [DRUPAL-

PATH]/core/lib/Drupal/Core/DrupalKernel.php on line 883 and defined in 

[DRUPAL-PATH]/core/lib/Drupal/Component/DependencyInjection/Container.php

 on line 119 #0 [DRUPAL-PATH]/core/includes/bootstrap.inc(550): 

_drupal_error_handler_real(4096, 'Argument 1 pass...', 

'/Applications/M...', 119, Array)

I need to clear cache programmatically.
