[PHP] Error while provisionning since `php8.0-json` package does not exist

[Kocal]

Hi! :wave:

I can finally try my work at #509 but I faced the following issue while running make setup or make provision:

TASK [manala.php : install > Packages presents] ********************************

(those commands are wrapper around vagrant provision)

It seems that the JSON support is already integrated to PHP since 8.0, there is no ext-json anymore and no package php8.0-json either.

I've tried to investigate a bit, but I don't understand how results to installing 'php8.0-cli' 'php8.0-fpm' 'php8.0-opcache' 'php8.0-readline' 'php8.0-json' 'php-xdebug' 'php8.0-mysql' 'php8.0-mbstring' 'php8.0-zip' 'php8.0-bz2' 'php-redis' 'php8.0-intl' 'php8.0-curl' 'php8.0-xml' 'php8.0-pgsql' packages.

Note that I don't require the JSON extension myself:

Do you know what can happens and how can we fix it? Thanks!

Hello 🤝

Yep, json extension is now embedded in php starting from version 8 :)

Here, at elao, we use a special condition to not include it, depending on php version. See: https://github.com/manala/manala-recipes/blob/master/elao.app/.manala/ansible/inventories/system.yaml.tmpl#L334

I'm afraid you are using our oooold and deprecated skeleton role, which don't handle this situation.. Am i right ?

[Kocal]

Well, yeah we always use the "old" skeleton generated by Manalize if I'm not wrong.

I'm will migrate to it and see what happens, thank you!

[nervo]

Feel free to contact me directly, we have solutions :)

For people having the same issue than me, I was able to not install the JSON extension by doing this:

# ansible/group_vars/app.yaml
app_patterns:
    # ...
    php_extensions:
        - extension: json
          state: ignore

        # Symfony
        - intl
        - curl
        - mbstring
        - xml
        # App
        - pgsql

Since this list is merged with the skeleton's php_extensions, passing state: ignore does not install the extension:

[Kocal]

I suppose we can close it, since a solution has been given and updating the outdated skeleton is not the right solution IMO.
