Gem files will remain installed in /var/lib/gems/1.9.1/gems/mongrel-1.1.5 for inspection.

我已經嘗試過sudo gem install mongrel --pre 甚至有--source

的一個

我不知道爲什麼它不工作。它是否與Ruby 1.9.1兼容？

Answer 1

You are not alone.在線程，然而，有a link to a possible fix。我沒有嘗試過，所以YMMV，但它似乎是一個似是而非的修復。

鑑於雜種不再被更新，不過，爲什麼不改用類似Thin？

編輯：對不起，我看到你問1.9.3。我的理解是雜種是（應該是）高達1.9.1兼容，但在1.9.2+打破。還有一個很好的理由轉向更現代化的東西和維護。

Answer 2

正如John乙所述，切換到薄。

由於無法使用Ruby 1.9.3安裝Mongrel進行安裝，因此我從Gemfile中註釋了Mongrel並添加了Thin。這讓我的應用程序完全安裝並運行良好。

在我的Gemfile

#gem 'mongrel', '1.2.0.pre2' 
gem 'thin' 

然後運行

bundle install 

Answer 3

以下命令，

gem install mongrel --pre 

效果很好。
