Install issues on php 7.1 (PS Checkout v5)

[Grandnainconnu]

Since about 3 weeks ago, I have been having a problem with my Docker tests for PrestaShop. I realized only today that this module is responsible for it.

2025-09-02 23:51:45 * Installing PrestaShop, this may take a while ...
2025-09-02 23:51:45 
2025-09-02 23:51:45 * Launching the installer script...
2025-09-02 23:52:13 Errors :
2025-09-02 23:52:13 Cannot install module "ps_checkout"

This error has been showing on any PrestaShop install with PHP 7.1, especially the ones I test 1.7.6, 1.7.7 and 1.7.8.

To reproduce, any Docker auto-install of these versions with PHP 7.1 will fail.

Hello, unfortunately there is very little information here to be able to help you 😞

I think if the install process fails there must be PHP error logs providing the exact reason why, they would be very helpful

Install issues could come from a very large number of issues, from permissions issues to incompatibility between modules

Any install with this setup will fail with only one message:

Errors :
Cannot install module "ps_checkout"

I saw later, by enabling debug mode, on the first PHP request, Composer issued a requirement warning for PHP 7.2.5, which is not normal because PrestaShop 1.7.6.0 works with PHP 7.1, cf their compatibility chart.

[Grandnainconnu]

I just install it to build my own module after PS installation, but the fact of having it would trigger the build of modules during PS install? That seems like a strange behavior.

My bad I think I read too fast

The composer error happens at runtime not at install time

Then I'm out of ideas 😅

[Grandnainconnu]

I'll try to install PrestaShop without Composer and then install it to see if the issue is still there.

[Grandnainconnu]

Just out of curiosity, though, why force PHP 7.2.5?

[matks]

Not sure but I think this line has very few impacts in our case because we build the module (and run composer install) from GitHub CI.

PS Checkout v5 core compatibility is 1.7.6 to 1.7.8 and these versions have php 7.1 and 7.2 in common

Hello we have other similar reports with install issues

and they seem to be related to this configuration item in the composer.json
so I am going to fix it in the next days, I keep you informed

[matks]

See #1362

Hello I think the release 5.0.3 should fix your problem @Grandnainconnu 😉 so I close this discussion
