Openzeppelin contracts import issue

I have these issues when I try to write my first NFT minting contract, anyone can help how to fix these?



when I try to run "npx hardhat clean" I got this:


Thank you very much!

:computer: Environment

I have installed hardhat, and github solidity extensions. and npm install @openzeppelin/contracts.

These are simple syntax errors. Strings use double quotes ", your import statement has simple quotes '.

The other error is self explanatory, I will not explain. Please read carefully.
