Hi there,

In addition to what has been mentioned I could suggest the following:

  • Make sure that you are actually using the new PHP version:
php -v

If you don’t get 7.4.0 back, then this means that you might still be using the old PHP version, if this is the case, then you could use the full path to your PHP binary, eg: /usr/bin/php74 /usr/bin/composer install or you could set the PHP 7.4 to be the default version so that you don’t have to specify the path.

  • Remove the composer.lock file and then run composer install again

Let me know how it goes.

Best,

Bobby

Hey @cutelapisdolphin,

This is due to the Composer configuration when you run composer install and the conflicts it generates with the Vendor folder.

There are several ways to solve it, but one of the simplest is.

Remove the packages you already have installed which includes this configuration from the composer:

  1. sudo rm -r vendor

Run the command again with this flag: --ignore-platform-reqs:

  1. composer install --ignore-platform-reqs

Hope that helps,
