Question

我在Windows机器上使用npm 3.10.10，并且我试图从包含npm install目录的目录上一级目录运行package.json ：

userfrosting/
    build/
        package.json

我正在使用prefix configuration option，这应该允许我这样做。在userfrosting/目录中：

npm install --prefix "build/" -ddd

这会产生以下错误：

npm ERR! eisdir EISDIR: illegal operation on a directory, read

如果我直接在npm install内运行build/，则效果非常好。我需要能够从这个父目录运行它，因为它是更大的构建工具的一部分。

此问题仅发生在Windows环境中 - 我已在* nix系统上运行它没有这个问题。

我的package.json按http://package-json-validator.com/传递验证。

完整的详细输出如下：
