Etheno migration issues

[fang19911030]

I tried etheno --truffle --ganache -p 7545 -i 5777 -x export.json mentioned here.
But there is no data in export.json.

Version info:
Etheno: ToB/v0.2.3/source/Etheno
Truffle: v5.1.59 (core: 5.1.59)
Solidity: - ^0.4.18 (solc-js)
Node: v10.19.0
Web3.js: v1.2.9
Here is my truffle-config.js

const HDWalletProvider = require('truffle-hdwallet-provider');
const infuraKey = "ktSpeXTL5DRPjaJ087hh";

const fs = require('fs');
const mnemonic = fs.readFileSync(".secret").toString().trim();

module.exports = {
  // See <http://truffleframework.com/docs/advanced/configuration>
  // to customize your Truffle configuration!
  compilers: {
    solc: {
      version: "^0.4.18"
    }
  },
  networks: {
    development: {
      host: "127.0.0.1",
      port: 7545,
      network_id: "5777",
    }
  }
}
