}above is my project package.json, when i run yarn hardhat compile, i get this error below:
Error HH411: The library @uniswap/v3-periphery, imported from @uniswap/universal-router/contracts/modules/MigratorImmutables.sol, is not installed. Try installing it using npm.
For more info go to https://hardhat.org/HH411 or run Hardhat with --show-stack-traces
error Command failed with exit code 1.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
I then go ahead to install @uniswap/v3-periphery, it then goes ahead to throw an error due to that fact the it requires openzeppelin v3.4.** , while univeral router requires v5.*. the imports are messed up and my contract that imports UniversalRouter is not just compiling
