Hi! It looks like your buidler project is failing to build; i.e. npx buidler compile is throwing an error. You will need to fix that first before attempting to run Slither.

Consider migrating your project to Hardhat or some other maintained build tool, Buidler is not being actively developed anymore and has not received any updates for around three years now: https://medium.com/nomic-foundation-blog/buidler-has-evolved-introducing-hardhat-4bccd13bc931

Sorry I did'n understand how can i solve error of npx buidler compile ? and also I have already set up hardhat and npx hardhat comile is also working without any error then how can i resolve this issue?

For your first question, you should consult with someone familiar with buidler, it's not an error from Slither.

For your second question, if you have hardhat set up already and working (i.e. your project has a hardhat.config.ts or hardhat.config.js file and npx hardhat compile works fine), slither should pick it up automatically when you do slither .. If it does not, try running slither-doctor . and see if that gives you a hint about what's wrong.

On second thought, I think buidler and hardhat have the same priority in Slither, so if you want to use hardhat over buidler you should use slither . --compile-force-framework hardhat (or just remove buidler.config.js, so your project only has hardhat in it, and use slither normally)
