一切都好！？不完全的。我现在再次尝试使用rails c来调出控制台。我还试图进行捆绑更新以及介于两者之间的所有内容。
LMagnotti$ rails c

....现在我陷入了一个永无止境的循环。有什么想法吗？
此外，经过明显的宝石原始 - 所有＆＃39;命令：这是我得到的。

然后再次运行rails c后，我们又遇到了同样的问题。
答案 0 :(得分：3)
我发现在安装了多个版本的ruby之后，我不得不为我当前使用的ruby版本创建一个gemset，然后在我成功打开rails控制台之前“使用”那个gemset。
答案 1 :(得分：1)
一般来说，您想要运行：
bundle exec rails c
这可以确保捆绑商为您处理所有宝石装载，并且您不会有任何意外。试一试。
答案 2 :(得分：0)
这为我解决了这个问题：
bundle clean
我有一些旧的宝石，它们是用不同的红宝石制成的。显然，这些副本缺少本机扩展名，但仍显示在加载路径中，导致类似于“忽略nokogiri-1.7.1，因为其扩展名未构建”的消息。
