mac os X上类HTTP的超类不匹配

标签： ruby-on-rails

我在Mac上安装Ruby on Rails环境时遇到了一些麻烦，我正在尝试使用这个版本：

  • ruby​​ 1.8.7（2011-06-30 patchlevel 352）[i686-darwin10.7.1]

  • gem 1.8.6

  • Snow Leopard 10.6.8

我认为默认情况下XCode会安装一些与我的某些宝石冲突的ruby库。要安装ruby，我使用过“rvm install 1.8.7”

这是错误的堆栈跟踪：

最后，我们在存储库中找到了另一个具有相同名称的类：

cd $HOME/.rvm/gems
find . -name *.rb | xargs grep 'class HTTP'

然后我们在net.ssh-2.1.4上看到一个HTTP类

./ruby-1.8.7-p352/gems/net-ssh-2.1.4/lib/net/ssh/proxy/http.rb:  class HTTP

为解决这个问题，我们强制要求'net / http'并在应用程序开头需要'net / https'。如果aplication要求默认gems首先需要net-ssh-2.1.4的HTTP类，那么我们就无法使用Net：HTTP。
