Problem: running command “composer install”, the error Warning: putenv() has been disabled for security reasons in” occurred.
In LNMP environment, the parameter “putenv” is disable by default.
Solution:
Go to php.ini and find disable_functions.
Then remove “putenv“.
Problem: Run composer update failed with a message “providing support and update for 1.x versions, please upgrade to Carbon 2.”
This is because of carbon version 1 is deprecated, you have to use Carbon 2, but Carbon requires Laravel 5.8
Solution: According to the official Carbon website, you can just update composer.json with below content:
{
"require": {
"nesbot/carbon": "2.25.0 as 1.39.0"
"kylekatarnls/laravel-carbon-2": "^1.0.0"
}
}
In this case, you can still be using other versions of Laravel
