Symfony 5.2 Error: The directory "var/cache/dev/jms_serializer" does not exist

Question

Symfony 5.2 with jms/serializer-bundle 3.7.0.

After symfony cache cleaning by command cache:clear on the next request I get an error:

The directory "var/cache/dev/jms_serializer" does not exist

I noticed that for symfony 4.4 $dir variable has var/cache/de_/jms_serializer value, but for symfony 5.2 has var/cache/dev/jms_serializer

So when symfony 5.2 runs warn up, JMSSerializerBundle creates jms_serializer folder in var/cache/dev instead of var/cache/de_

serializer config:

jms_serializer:
    visitors:
        xml_serialization:
        format_output: '%kernel.debug%'
    property_naming:
        id: 'jms_serializer.identical_property_naming_strategy'

Try to just remove cache directory.

rm -rf var/cache

And create it with php user:

sudo su www-data // Login as php user
mkdir var/cache // create cache directory
chown -R $USER:$USER var/cache // Change owner of cache directory

where instead of www-data is the user which run your php.

P.S. I am not fully sure, but there is no var/de directory neither for symfony, neither for serializer. It is just an temporary directory created by symfony while clearing cache process, which is usually removed after successful finish

Thanks, but I have to use `cache:clear` command. If I'm not mistaken `var/de_` directory is used for warn-up cache and this directory will be renamed to `var/dev` when original `var/dev` directory are deleted. – Artem Dec 18 '20 at 09:08
I believe that old `de_` directory is messed up and does not let override cache with new one. You need to delete it somehow. – Urmat Zhenaliev Dec 18 '20 at 10:17
`var/de_` directory isn't removed, it's renamed to `var/dev` after successful finish, see https://github.com/symfony/symfony/blob/8b51547061b29081803eb9fdf9b02cf80a1e1a74/src/Symfony/Bundle/FrameworkBundle/Command/CacheClearCommand.php#L177 – Artem Dec 18 '20 at 14:47
symfony fixed that in 5.2.1 version – Artem Dec 18 '20 at 14:53
