在尝试将 ThinkingTank gem 包含到我的 rails 项目中时，我遇到了一个令人讨厌和奇怪的问题。当我在项目的 Gemfile 中包含 gem 'thinkingtank' 时，出现以下错误：

ruby -v 的输出是：

ruby 1.8.7 (2009-12-24 patchlevel 248) [i686-darwin10.6.0], MBARI 0x6770, Ruby Enterprise Edition 2010.01

rails -v 的输出是：

Rails 2.3.5

我已遵循 their documentation 和 similar SA questions 的基本准则。但是没有任何问题导致rails gem 丢失..

是的，我们在 Gemfile 中包含了 rails =)

提前谢谢你。

【问题讨论】：

尝试：在您的 gem 文件中要求 'thinkingtank'。
嗨，Harry，感谢您的评论，尽管已经需要 thinktank。

【解决方案1】：

我最终通过删除“require rails”语句解决了这个问题。还有其他一些导致问题的 gem 冲突，但我能够通过对源代码进行一些小的更改来解决它们。谢谢！
