Gulp RequestError：连接 ECONNREFUSED 127.0.0.1:80

Question

在我不得不重新安装 Windows 之前，我有一个可以在我的计算机上运行的 gulpfile。 我几年前写的，老实说，Gulp 不是我在此之外使用的东西，所以我的理解和记忆是有限的。

这真的很基本——它只是在我的项目中获取 CSS 和 javascript 更改，将它们缩小文件并将它们放在 webroot 中。 然后它有一个“监视”任务来监视更改并在完成后再次运行它。

我已经全局安装了 node 和 gulp，最初 Python 安装失败。 我设法手动安装了它，然后在我的项目目录中运行“npm install”。 这似乎有效，我可以看到 node_modules 文件夹。

当我“吞咽”时，它会正确执行并处理我的所有文件。 然后它报告它完成了最后的“监视”任务，这是我 gulpfile 中的最后一件事。

然后我收到一个错误，该过程结束，而不是像往常一样关注我的更改。

这是我收到的错误。 我试过用谷歌搜索，但我找不到任何线索，所以任何帮助都将不胜感激。
