css - rake Assets :precompile not working - Windows 7

Question

我的 css 文件和缓存有问题。现在似乎没有加载任何样式表，我读到我可以尝试使用 rake assets:precomile，但我收到错误。

当我使用 trace 运行时:

C:\Users\admin\Desktop\webapp>rake assets:precompile --trace
** Invoke assets:precompile (first_time)
** Execute assets:precompile
"C:/Program Files/ruby-1.9.2/bin/ruby.exe" C:/Program Files/ruby-1.9.2/bin/rake assets:precompile:all RAILS_ENV=producti
on RAILS_GROUPS=assets --trace
rake aborted!

有人知道如何解决这个问题吗？提前致谢。

状态代码 127 通常用于指示“未找到命令”。在您的情况下 ["C:/Program Files/ruby-1.9.2/bin/ruby.exe"...]，未找到 ruby​​.exe。你是否正确安装了 ruby ？
