Problem during Laravel set up with Docker Compose

As I was following through the tutorial on the same topic (, I successfully pass 7 steps, but faced error on step 8 on generating a key and copy it to your .env file: “Your Composer dependencies require a PHP version “>= 7.3.0”. You are running 7.2.34. in /var/www/vendor/composer/platform_check.php on line 24 ERROR: 255” How can I fix this problem?

Hi, @bobbyiliev,

Thank you for you answer, but unfortunately it didn’t help. May be it needs reloading?

Hi there @lmilakorn,

In the Dockerfile make sure to change this line:

FROM php:7.2-fpm


FROM php:7.4-fpm

Let me know how it goes!

Regards, Bobby
