问题出在哪里？

  

您在 Windows 上使用 sqlite3 数据库 Rails ！

我的Windows 10上也出现了类似的错误警告！

错误位于何处？

  

错误位于 gemspec 文件夹中！

在 Windows 8 上找到 gemspec 文件夹： C:\Ruby21\lib\ruby\gems\2.1.0\specifications。

如果您正在使用RailsInstaller，请访问：C:\RailsInstaller\Ruby2.1.0\lib\ruby\gems\2.1.0\specifications！

手动修复

  

您应该根据您的Rubygem路径和sqlite3版本进行调整。

编辑

的文件
  • 的 sqlite3的 -4.1.5.gemspec
  • 的的ActiveSupport -4.1.5.gemspec
  • 的架 -4.1.5.gemspec
  • 的 railties -4.1.5.gemspec

并查找以下行：

s.require_paths=["lib"]

将其更改为：

s.require_paths= ["lib/sqlite3_native"]

有用的链接

  

您的问题类似于cannot load such file -- sqlite3/sqlite3_native (LoadError) on ruby on rails！
