Rails服务器“需要”无法加载此类文件

Question

我决定开始学习ruby / rails，并通过RubyInstaller将其安装在我的Windows机器上。 我安装了2.2.0，安装了DevKit，运行了gem install rails ，并且工作正常。

然后，我创建了一个新项目并创建了rails new project并创建了文件夹并在其中运行bundle install 。 但是，当进入项目文件夹并运行rails server ，出现以下错误：

C:/Ruby22/lib/ruby/gems/2.2.0/gems/sqlite3-1.3.10-x86-mingw32/lib/sqlite3.rb:6:i

我最初尝试在SO上关注另一个问题，并尝试了rake db:create但是SQLite遇到了类似的错误。 在另一个问题中，他们建议将s.required_pa​​th从['lib']更改为['lib/sqlite3_native']或类似名称，并修复了SQLite的错误，但未修复其他错误。 对我来说，遍历每个gem配置并修复它是不切实际的，也是不可能的。

纠正这些宝石的路径的最佳方法是什么？

如在此sqlite GitHub问题中所述 ，似乎不支持您正在使用的特定版本的Ruby。 这似乎是Windows平台上特别存在的问题。 如果您确实无法更改任何其他环境变量，则也许现在应该降级Ruby版本。
