Question

尝试使用Rails 3.2.2运行以下命令，切换到3.2.1并尝试使用另一台计算机来查看它是否与核心/操作系统相关。

我试试：

rails g bootstrap:themed events

我明白了：

.rvm/gems/ruby-1.9.3-p0/gems/activesupport-3.2.1/lib/active_support/inflector/methods.rb:229:in `const_defined?': wrong constant name event (NameError)
    from /Users/charleyhine/.rvm/gems/ruby-1.9.3-p0/gems/activesupport-3.2.1/lib/active_support/inflector/methods.rb:229:in `block in constantize'
    from /Users/charleyhine/.rvm/gems/ruby-1.9.3-p0/gems/activesupport-3.2.1/lib/active_support/inflector/methods.rb:228:in `each'

    from (erb):6:in `template'

Answer 1

无需降级宝石版本。相反，只需改变：

rails g bootstrap:themed events

为：

rails g bootstrap:themed Events

您需要将模型名称大写并复数化，这是愚蠢的，但它可以正常工作

Answer 2

我得到了同样的错误。在搜索类似的错误之后 - 我认为它必须是最新版本的bootstrap的问题，因为我之前没有收到此错误。

我在2.0.4版本中遇到了错误。 Gemfile中的以下行后跟“bundle install”解决了它。

gem'twitter-bootstrap-rails'，'2.0.2'

bootstrap：主题错误的常量NameError - ＆gt; const_defined？
