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

我已经尝试过sudo gem install mongrel --pre 甚至有--source的那个

我不知道为什么它不起作用。它与 Ruby 1.9.1 及更高版本兼容吗？

【解决方案1】：

You are not alone. 但是，在线程中，有a link to a possible fix。我还没有尝试过，所以 YMMV，但这似乎是一个合理的解决方案。

鉴于 Mongrel 不再更新，为什么不切换到 Thin 之类的东西？

编辑：抱歉，我看到你问的是 1.9.3。我的理解是 Mongrel （应该）与 1.9.1 兼容，但在 1.9.2+ 中被破坏。还有一个很好的理由来切换到更现代和维护的东西。

【解决方案2】：

在命令下，

gem install mongrel --pre

效果很好。

【解决方案3】：

正如 John B 所说，切换到 Thin。

在无法使用我当前的 Ruby 1.9.3 设置安装 Mongrel 后，我从我的 Gemfile 中注释掉了 Mongrel 并添加了 Thin。这让我的应用完全安装并运行良好。

在我的 Gemfile 中

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

然后运行

bundle install
