Installation issue | symfony/cache does not support 6.1 version

[LeVadim]

Hello!

Your package does not support cache version 6.1, could you please bump it up in composer.json? Thank you!

- colopl/laravel-spanner[dev-master, v3.6.0, ..., v3.9.2] require symfony/cache ~4|~5 -> found symfony/cache[v4.0.0-BETA1, ..., 4.4.x-dev, v5.0.0-BETA1, ..., 5.4.x-dev] but the package is fixed to 6.1.x-dev (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.

Hi, thanks for raising the issue.

This is not possible yet because laravel 8 does not support symfony v6.
I believe it will be supported when laravel 9 is released later this month.

Hi @taka-oyama ! It is almost working now. Currently getting the following error:
ParseError {#1842

Can you please check it out? Thank you.

I'm not getting that error in my setup.
That error looks like it's coming from google/gax.
Please try updating google/gax to the latest version.

It does seem like its incompatible with PHP 8.1, that ReadOnly is a reserved name
Sample error - schmittjoh/serializer#1331

Whom would you suggest reaching out to regarding this issue? Thank you.

I have created a thread with gax-php
Link is here - googleapis/gax-php#374

Looking at the errors again, I think this might be something google/cloud-spanner needs to fix by renaming their class.

[taka-oyama]

I raised the issue in google-cloud-php. Hopefully they will fix it soon.

[taka-oyama]

Seems like we're finally getting some progress.
https://github.com/protocolbuffers/protobuf/releases/tag/v3.20.0

Fix: add missing reserved classnames (protocolbuffers/protobuf#9458)
PHP 8.1 compatibility (protocolbuffers/protobuf#9370)

Unfortunately there is a problem building 3.20.0 (protocolbuffers/protobuf#9727) in pecl so we'll have to wait until that's resolved as well.

[taka-oyama]

Status update.

Protobuf v21.0 was released with the fix for PHP 8.1.

Now all we need is a fix on google-cloud-php (googleapis/google-cloud-php#5129) side and we would be able to update to PHP 8.1 which Symfony 6.1 requires.

[taka-oyama]

Seems like googleapis/google-cloud-php#5129 was fixed in google/cloud-spanner 1.51.0.
I updated to php 8.1 and the tests seems to pass fine.

So running composer update google/cloud-spanner should make everything work (Including symfony cache v6.1).

Please check it out.

[taka-oyama]

I will close this for now since my environment is working under PHP 8.1 / Symfony 6.1.

Please reopen if you continue to encounter errors.
