@lisong ok 好的

[lisong]

if (_.isString(argv.dbpassword) || _.isNumber(argv.dbpassword)) {
    dbpassword = _.toString(argv.dbpassword);
}

改成这样应该好些

这也可以，但是已经使用yargs库来解析cli参数，这样做相比简单一些 。

[lisong]

如果yargs有这样的功能，那可以去掉

if (_.isString(argv.dbpassword) || _.isNumber(argv.dbpassword)) {
    dbpassword = _.toString(argv.dbpassword);
}

这个判断

[lisong]

upgrade 这个命令是否也需要配置这种配置？
