Why after installing any package and restart the bench it is not installed!

Why after installing any package like “pydantic” and restart the bench it is not installed !!!
WARNING: Package(s) not found: pydantic

Hi,

May we know the operating environment and how the package is being installed?

Does the warning appear when you bench restart or somewhere else?

appear into the desk!

Try: pip3 install frappe-bench --upgrade
