Error: Undefined constant "CodeIgniter\CLI\STDERR"

Hi, all, have been working on php spark, than i wanted to went to nginx, on first error got unwritable writable/cache, which solved by chmod 775, now I got that error: 

SYSTEMPATH/CLI/CLI.php at line 488
Have been looked in php.net/search engine did not found info about that const...  

New info: that was because i used: var_dump(command('logs:clear')); 

Seems I misunderstood and that function is only for CLI... Forgot i was used $migration->latest(); & cache()->clean();

I don't recommend to use CLI command via web.
But If you really want to run it, try:

Code:

--- a/system/CLI/CLI.php
+++ b/system/CLI/CLI.php

+            define('STDERR', 'php://output');
        }
    }
