我正在建立一个Ruby on Rails生产环境。我正在使用RVM的多用户安装。运行rake资产时：预编译我收到以下错误。其他rake任务似乎工作正常。

Tasks: TOP => assets:precompile
错误似乎表明找不到Ruby，但事实并非如此：
$ ls /usr/local/rvm/rubies/ruby-1.9.3-p448/bin/ruby
/usr/local/rvm/rubies/ruby-1.9.3-p448/bin/rub
此外，我可以成功运行资产：使用rake through ruby进行预编译，如下所示。我从上面显示的错误中得到了这个想法。这很奇怪，因为这似乎是导致问题的原因。但手动运行它。
$ ruby /usr/local/rvm/gems/ruby-1.9.3-p448@global/bin/rake assets:precompile RAILS_ENV=staging
为什么会这样？这可能与我使用多用户或全局安装RVM的事实有关吗？

答案 0 :(得分：4)
我遇到了同样的问题。我通过恢复到ruby-1.9.3-p392来修复它，此时我收到了关于可执行挂钩的错误，这引出了我这个问题。然后我跑了：
rvm ruby-1.9.3-p392@global do gem install executable-hooks
基于mpapis的答案（谢谢你！）现在一切似乎都在为我工作。
我原来的问题在这里：rake assets:precompile error message: No such file or directory -- ruby
答案 1 :(得分：2)
运行：
rvm ruby-1.9.3-p448@global do gem install executable-hooks
