my name is akshat faganiya and i belongs to chital gujarat currently i am student of software engineering fields. during my third year project developing this error are occur. because i have also decide i will make project using python using PyQt6 and his designer tool so in starting when i install package there are some critical error are invented. like ....................

1.the sub process error 2.metadata generation failed 3.toml.py file not found

this all error had occurred only one problem that python PyQt6 version ae not compatible with latest version so . before you get make Tention must download compatible version of the pyhon.

so if you want to defeat all this error then download python 3.9.0 version this is then only way.
