Express服务器：错误：请求的范围不满足
我写我的第一个节点的Web服务器（随意给我反馈），使用快递和Gith部署。 问题是一旦部署，我收到了下面的错误，如果我通过pm2运行脚本，这个过程似乎被删除。 有任何想法吗？ 脚本附在下面。

你不应该使用require('https')吗？ 也调查express.static …
看起来错误是从你的deploy.sh脚本中出来的。
要解决这个问题，请确保传出的请求没有Content-Range 。
也可以帮助发布deploy.sh
尝试将acceptRanges：false作为parameter passing给res.sendFile方法。
因此，不是调用res.sendFile(filePath)而是使用res.sendFile(filePath, {acceptRanges: false})
