Cachet: php artisan app:install error

[captainhook]

Hi,

I've setup CentOS 7.4 with PHP 7.2.2 and all the required plugins.

When running php artisan app:install, I get:

Is this down to a compatibility issue?

[captainhook]

Ok it seems for 7.2.1 I would need 2.4 branch.

[nickparker39]

@captainhook In PHP 7.2, a non-countable object displays a warning as seen here. It looks like the way the ExceptionIdentifier is written caused a backwards incompatible change. "Environments that display warnings or convert them to more severe errors/exceptions would be affected, but this should just bring attention to a bug in the code."

I'm having the same issue, so I'll do some research and try to come up with a fix.

[MarkL4YG]

I can confirm this.
Cachet is not compatible to PHP7.2 (at least for Ubuntu 16.04 LTS + Apache2) due to this error.
Edit: Adjusting the title may raise awareness btw.

[nickparker39]

This appears to be an error with Graham Campbell's Exception package for Laravel. It hit a snag with 7.2 based on the count() method not receiving a countable object. I've submitted a PR for it here.

[MarkL4YG]

upgrade to 9.4 or higher, where I fixed this

Given the fact he's part of the Cachet team they should already know that they'd need to update the dependency. 🤔

[nickparker39]

@captainhook update the exceptions package from Graham Campbell to ^9.4 in your composer.json and it should work for now.

$ composer require "graham-campbell/exceptions:^9.4"

[MarkL4YG]

Sounds good. As long as this is still compatible of course.

[nickparker39]

@MarkL4YG i'm actually running it right now and i'll update you as soon as i complete the install.

[MarkL4YG]

That was fast xD. Great news 👍

[nickparker39]

Updating the exceptions package to 9.4 does not have any effect on it. There is still some instance that is being passed that is not Countable. I don't see why having a function to check if it is countable is an issue. This is a breaking change that doesn't work with PHP 7.2, yet having that function passes all tests and fixes the 7.2 issue.

[GrahamCampbell]

With that PR, if you can fix the thing that is causing the variable to be set to null, that would be really great, rather than adding a check.

[nickparker39]

@GrahamCampbell will do, thanks!

[JacobDB]

What's the status on this? I'm still seeing this nearly 2 years later.

[aiso-net]

Im having the same issues as well

[captainhook]

You guys might want to share some logs/copy of the error so we can see what exactly is happening.

@JacobDB if you read all the messages above, you'll see I was using an incompatible version of PHP. Since then Cachet has been updated to work with PHP 7.1.3 – 7.3.

[aiso-net]

I fixed it, it was due to php version 7.3 and not being on 2.4, switching php to 5.6 fixed it, thanks.

@aiso-net switching to PHP 5.6 is not a fix. PHP 5.6 was EOL over a year ago. Any PHP apps you use should be using at minimum PHP 7.2 and preparing to migrate to PHP 7.3+.
Cachet is fully compatible with PHP 7.3, so you need to have a look at your error message/logs and go from there.

Having this same error with php7.4.3 during install, specifically on the postinstall step artisan optimize --force. Cachet from master

[josephworks]

Yep, php7.4 here and still an issue. Why is this closed?

[GrahamCampbell]

Cachet does not support PHP 7.4 yet.

[josephworks]

That's right, my bad. But, I tried 7.3 and it also didn't work. I fixed the issue but I forgot how.

[WeebHiroyuki]

I can still experience this issue. I'm on PHP 7.3.

[w4rc0n]

On php7.2, still experiencing this issue.

[jdwoj5]

On php7.4, still experiencing this issue.
