无法使用中间人构建 ruby​​ 项目

Question

我正在做以下事情：

gonvaled@pegasus $ bundle exec 'middleman build --verbose'

...
== Finishing Request: pages/forms/forms.html (0.04s)
      update  build/pages/forms/forms.html
       error  build/javascripts/vendor/jquery.easy-pie-chart

很多东西都在正常构建，但有些东西像这样失败了。我不知道是什么失败了：ruby 没有提到输入文件的任何具体问题：jquery.easy-pie-chart.coffee 似乎没问题。

我可以尝试调试什么？我是 ruby​​ 和中间人的新手。

Answer 1

您可能需要安装 javascript 运行时，例如 therubyracer。

Answer 2

我的系统在PATH 中有一个名为nodejs 的（虚假）可执行文件，它阻止了真正的nodejs 运行。没有提供关于此的消息，因此真的很难找到。
