bun-cli工具是一个融合了多种实用功能的前端命令行工具，它服务于bunjs框架，却不止于bunjs。

const config = require('../../config/config.js');
const prompt = require('co-prompt');

const chalk = require('chalk');
const download = require("download-git-repo");
const rm = require('rimraf');
const fs = require('fs');
const {
    fsExistsSync
} = require("../../utils");

        let downloadPath = config[option].downloadPath;
        initFiles(downloadPath, appName, fileMap);
    });
}
