- 这里其实一句
argv.sourcemap = undefined也够了。 上面有个 https://github.com/eggjs/egg-scripts/blob/ts/lib/command.js#L16 会自动删除别名。 - 之前的想法是，上层业务框架可能会自定义一些入参，这里更倾向于黑名单机制，也就是明确在工具层用的入参，在这里删掉。否则白名单机制的话，上层业务框架就要定制 egg-scripts 。

ts 支持生成 sourcemap，这里是用来根据 sourcemap 还原堆栈的。可以看看 https://zhuanlan.zhihu.com/p/26267678
之前这个 require 都是放到 config 或 app.js agent.js ，或者放框架。
现在这个 PR 是直接在工具层引入了。
