PHP 7.4 doesnt work

[iiru]

Hello,

cannot launch Magento 2.3.3 on php 7.4.

It says:

Problem: magento/product-community-edition 2.3.3 requires php ~7.1.3||~7.2.0||~7.3.0 -> your PHP version (7.4.0RC4) does not satisfy that requirement.

How can I run it on Php 7.4?

Thank you.

Hello @iiru 

Magento 2 hasn't added support for php 7.4

Check  out Magento 2 release notes

Magento 2.3.3 now supports PHP 7.3.x (tested with PHP 7.3.8) and PHP 7.2.x (tested with 7.2.21).

Hi @iiru 

Currently php7.4 is not added in magento.

So you can just install php 7.3 in addition to php7.4 and set php7.3 as primary.

Then you will be able to run your magento.

Thanks

Eu forcei a instalação alterando o arquivo composer.lock na linha 

"php": "~7.1.3||~7.2.0||~7.3.0||~7.4.1",
