Web/app/cache/acorn/framework/cache directory must be present and writable

Hello
I installed bedrock / sage / acorn before but it’s he first time I have this message when i select sage theme in my wp admin.

web/app/cache/acorn/framework/cache directory must be present and writable.

Not sure to know what is happening. I am on wsl ubuntu. Could someone help me to look in the right direction ?
Thnak you so much in advance.

Is there a directory under web/app/cache/acorn/framework/cache, in the Bedrock/WordPress site directory? What owner/group and what permissions has it?

No. I had to create it manually and change user permission to make www-data the owner.

That directory should be created automatically in recent
Sage 10 (acorn) (see this related issue).
What version of Sage 10 and also acorn is the project using?

Hello
I use sage 10 on WSL Ubuntu. To solve the problem, I had to create the the directory manually and change permission to ww-data.
Hope that helps if someone has the same issue.
