如何修复Rails 3.1和Ruby 1.9.2中的语言学库中的错误

Question

在rails的最新版本中，我的应用程序有以下几行代码：

gem 'linguistics' # in Gemfile

Linguistics::use(:en, :installProxy => :en) # In environment.rb

最近，我从Ruby 1.8.7升级到Ruby 1.9.2，并使用Rails的edge版本。当我启动服务器时，我现在看到以下内容：

你知道我该怎么解决这个问题吗？这是语言学和Ruby 1.9.2之间的不兼容吗？

Answer 1

我认为这主要是rails的兼容性问题，因为在commits 1.9.2 compat中提到了，一个接一个地尝试，而不是两个一起尝试，以确保1.9.2和rails 3工作，然后切换到edge rails。

你可能想试一下，如果有一个实际的版本，试一下(将这个版本包含在你的gemfile中)：

gem update linguistics --pre

或者确保在您的gemfile中更新它。

gem 'linguistics', :git => 'https://github.com/ged/linguistics.git'
