java - 如何在 Windows 上的 eclipse 中运行 nutch 1.9？

Question

我想在 Windows 上的 Eclipse 中运行 Nutch 1.9。我遵循了 http://wiki.apache.org/nutch/RunNutchInEclipse 中的教程并在 Eclipse 中打开项目。

但是当我运行 Nutch 时，出现以下错误:

似乎是 Hadoop 导致了错误。我不知道如何解决这个问题。我知道 Nutch 需要 Unix 环境。但是，我想在 Windows 上的 Eclipse 中运行 Nutch。

谁能帮我解决这个问题？

Answer 1

下载 cygwin，然后将其添加到环境变量的路径中。我认为你的问题是由 Windows 无法调用 unix native 命令这一事实引起的。这就是我所做的，但是一旦我解决了那个问题，我就遇到了其他问题。
