无法启动Windows上的rails服务器8

Question

我正在关注ruby教程，并在运行'rails s'时出现此错误。

此前工作正常，但现在我无法启动rails服务器。这似乎是我在rails中改变了一些东西。

问题出在哪里？

您使用的是sqlite3的数据库Rails的上的Windows！

我的Windows 10上也有类似的错误警告！

---

错误在哪里？

的错误是在你的gemspec文件夹！

查找您的Windows 8您gemspec文件夹： C:\Ruby21\lib\ruby\gems\2.1.0\specifications。

如果您使用的是RailsInstaller请参阅：C:\RailsInstaller\Ruby2.1.0\lib\ruby\gems\2.1.0\specifications！

修复它手动

您应该与Rubygem路径和sqlite3的版本根据调整。

编辑文件

• sqlite3的 -4.1.5.gemspec
• 的ActiveSupport -4.1.5。gemspec
• 架 -4.1.5.gemspec
• 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"]
