【中文标题】红宝石 紫外线、导轨、豹纹

【英文标题】：Ruby Gem Ultraviolet, Rails, Leopard

【问题描述】：

我无法让这种疯狂的依赖发挥作用，请不要因为我有 PPC 而告诉我去 Snow Leopard。

我已经安装了oniguruma、textpow、紫外线。我正在使用 rvm 这可能是问题所在。不是 rvm 不好，只是我不知道如何让路径正确。

当我启动一个 Rails 应用程序时，我收到的错误是我错过了 ultraviolet gem，事实并非如此，因为它与其他正常工作的 gem 一起列在 gem list 下。

如果您需要更多信息以及具体的信息，请告诉我：

这是我的错误日志：

【问题讨论】：

也许在这里发布您的gem env 确保您使用的是您认为的 ruby​​ 版本。您也可以尝试在 environment.rb 中调整您的 gem 路径。总帐。

【参考方案1】：

对于 Rails 3、Rails 4 和 Rails 5，你应该有Gemfile，

gem "ultraviolet", :require => "uv"

【参考方案2】：

I didn't add :lib => 'uv'

Rails::Initializer.run do |config|
    config.gem 'ultraviolet', :lib => 'uv'
end

【参考方案3】：

安装 gem 与在 Rails 配置中声明它不同，尽管它是一个重要的先决条件。

确保您的 config/environment.rb 至少设置了：

Rails::Initializer.run do |config|
  config.gem 'ultraviolet'
end

在您使用gem 命令声明它们之前，不会自动加载宝石。也许它很顽固，所以试试这个：

% irb
> require 'rubygems'
 => true
> gem 'ultraviolet'
 => true
> $:.grep(/ultraviolet/)
 => [...]

最后一行应该显示库 $: 的加载路径已调整为使用您的 rvm 托管 gem。它可能会丢失或不正确，这会阻止 gem 正确加载。

如果您使用的是 RVM 并且您的环境不一致，通常很容易运行错误的 ruby 或 irb。如果您不小心自己的路径，gem 经常会绑定到错误的 ruby​​。
