我试图在truffle中创建一个测试，用以下代码将它连接到ganache：-

const path = require("path");

module.exports = {
  // See <http://truffleframework.com/docs/advanced/configuration>
  // to customize your Truffle configuration!
  contracts_build_directory: path.join(__dirname, "client/src/contracts"),
  networks: {
    development: {
      port: 7545,
      host : "127.0.0.1",
      network_id :5777,
    }
  },

  compilers:{
    solc: {
      version: "0.6.1"
    }
  }
}

但我得到了这个错误。不过，合同编制成功。有什么办法吗？？
我收到的错误信息：-
