耙资产：预编译找不到红宝石

Question

我正在设置一个 Ruby on Rails 生产环境。我正在使用 RVM 的多用户安装。运行 rake assets:precompile 时出现以下错误。其他 rake 任务似乎运行良好。

ruby@myserver:/sites/rails/necura_staging/shared/cached-copy$ bundle exec rake assets:precompile --trace

Tasks: TOP => assets:precompile

该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，我可以在通过 ruby​​ 使用 rake 时成功运行 assets:precompile ，如下所示。我从上面显示的错误中得到了这样做的想法。这很奇怪，因为这似乎是导致问题的原因。但是手动运行它是可行的。

$ ruby /usr/local/rvm/gems/ruby-1.9.3-p448@global/bin/rake assets:precompile RAILS_ENV=staging

有什么想法吗？这可能与我使用多用户或全局安装 RVM 的事实有关吗？

谢谢

Answer 1

我遇到了同样的问题。我通过恢复到 ruby​​-1.9.3-p392 来修复它，此时我收到有关可执行挂钩的错误，这导致我提出了这个问题。然后我跑了：

rvm ruby-1.9.3-p392@global do gem install executable-hooks

基于 mpapis 的回答（谢谢！），现在一切似乎都对我有用。

我原来的问题在这里：rake assets:precompile error message: No such file or directory -- ruby

Answer 2

运行：

rvm ruby-1.9.3-p448@global do gem install executable-hooks
