红宝石紫外光、导轨、豹纹

Question

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

我已经安装了oniguruma、textpow、ultraviolet。我正在使用 rvm 这可能是问题所在。并不是说 rvm 不好，只是我不知道如何使路径正确。

当我启动 Rails 应用程序时，我收到的错误指出我缺少 ultraviolet gem，但事实并非如此，因为它与其他 gem 一起列在 gem list 下哪些工作正常。

如果您需要更多信息以及具体信息，请告诉我：

这是我的错误日志：

Answer 1

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

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

Answer 2

我没有添加：lib => '紫外线'

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

Answer 3

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

确保您的 config/environment.rb 至少设置为：

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

在使用 gem 命令声明它们之前，Gems 不会自动加载。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。它可能丢失或不正确，这会阻止 gem 正确加载。

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