无法在 Jruby 9.1.12.0 上安装 Watir - Windows 7

Question

我正在尝试将 gems 从本地 gem 存储库安装到 Jruby 9.1.12.0 中，但我卡在了 Watir 上，这几乎是我尝试的第一个。

我运行 Windows 7 JDK 1.8.0_131

我得到以下信息：

Error installing watir:
ERROR: Failed to build gem native extension

看起来错误消息的其余部分似乎是在抱怨 ffi-1.9.18 恐怕我无法 post 确切的错误消息，因为它位于未启用 Internet 的 VM 中.

更新：完整错误信息：

C:\Ruby\gem>jruby -S gem install watir

Answer 1

我现在开始工作了。从错误消息中可以明显看出 'Make' 没有被正确定位。我在路径中添加了正确的目录，并且 Watir 已正确安装。
