如何解决npm hardhat 运行后连接到本地主机时出错
我是使用安全帽部署智能合约的新手,正在学习 https://dev.to/dabit3/the-complete-guide-to-full-stack-ethereum-development-3j13 上的教程。但是,在运行 npx hardhat run scripts/deploy.js --network localhost
后,出现以下错误。关于如何解决连接问题的任何想法?
HardhatError: HH108: Cannot connect to the network localhost.
Please make sure your node is running,and check your internet connection and networks config
