按照 friend 发给我的指南，我尝试了 rails s。
我在运行 rails s 时遇到这些错误
首先我会展示ruby和rails的版本
C:\>ruby -v
ruby 2.2.2p95 (2015-04-13 revision 50295) [x64-mingw32]
C:\>rails -v
Rails 4.2.1
C:\>
我运行 rails new qwerty 一切顺利
C:\rubyblah>rails new qwerty

C:\rubyblah\qwerty>
我发现这是关于第一个错误
cannot load such file -- sqlite3/sqlite3_native (LoadError) on ruby on rails
于是我按照说明编辑了相应的gemspec文件
C:\>dir sql*.gemspec /s/b
C:\Ruby22-x64\lib\ruby\gems\2.2.0\specifications\sqlite3-1.3.10-x64-mingw32.gems

我编辑该 gemspec 文件，将 s.require_paths = ["lib"] 更改为 s.require_paths = ["lib/sqlite3_native"]
然后当我运行 rails s 时，我得到了一大堆新的错误

最佳答案
一个选项是将 ruby 降级到一个稳定的/与 windows 一起工作的版本。另一种选择是安装 Linux VM 并在那里安装 Ruby。
您需要安装与 Windows 兼容的 Ruby 版本。
不是最新版本的 Ruby。在撰写本文时，最新版本是 2.2.2，并且在 Windows 中不稳定。
即使您使用的是 64 位机器，稳定的 Windows 版 Ruby 也是 32 位的。
你想要 Ruby 2.1.X 例如Ruby 2.1.6(最新的 2.1.x 很好，2.1.6)而且你想要 32 位版本
http://dl.bintray.com/oneclick/rubyinstaller/rubyinstaller-2.1.6.exe
就是这里提到的http://rubyinstaller.org/downloads/ “我们建议您使用 Ruby 2.1.X 安装程序。它们提供了一种稳定的语言和广泛的兼容和更新的包(gems)列表。
但是，并非所有包( gem )都得到维护。一些较旧的软件包可能与较新版本的 Ruby 和 RubyInstaller 不兼容。
Ruby 的 64 位版本在 Windows 领域相对较新，并非所有包都已更新以与其兼容。要使用此版本，您需要了解一些编译器和解决依赖性问题的知识，如果您只是想使用该语言，这可能太复杂了。”
记下那条指令
因此请删除您当前拥有的所有 Ruby。
要删除 Ruby，请转到开始菜单..Ruby..，然后单击“卸载”。
那也应该卸载 Rails。
并移除任何开发工具包。 devkit 可执行文件通过提取到您指定的文件夹进行安装，因此只需 rmdir/删除该文件夹即可。
现在安装那个稳定的 ruby.. 2.1.6 32 位 安装 rails 和 devkit
安装rails的命令
gem install rails
安装 devkit 确保你有正确的 devkit
例如
http://rubyinstaller.org/downloads/
WHICH DEVELOPMENT KIT?
....
Ruby 1.8.6 to 1.9.3: tdm-32-4.5.2
Ruby 2.0.0 and above (32bits): mingw64-32-4.7.2
Ruby 2.0.0 and above x64 (64bits): mingw64-64-4.7.2
所以你想要
Ruby 2.0.0 及更高版本(32 位):mingw64-32-4.7.2
查看可用的开发包
开发工具包
与 Ruby 1.8.7 和 1.9.3 一起使用:
DevKit-tdm-32-4.5.2-20111229-1559-sfx.exe
用于 Ruby 2.0 及更高版本(仅限 32 位版本):
DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe
用于 Ruby 2.0 及更高版本(仅限 x64 - 64 位)
DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe
你想要
DevKit-tdm-32-4.5.2-20111229-1559-sfx.exe
用于 Ruby 2.0 及更高版本(仅限 32 位版本):
http://dl.bintray.com/oneclick/rubyinstaller/DevKit-mingw64-32-4.7.2-20130224-1151-sfx.exe
按照此处的说明安装 devkit https://github.com/oneclick/rubyinstaller/wiki/Development-Kit
假设你把它放在 c:\devkit 中
c:\devkit>ruby dk.rb 初始化
c:\devkit>ruby dk.rb 安装
虽然我认为没有必要，但您可以运行此命令 c:\sdfsd>gem 安装 json --platform=ruby
所以现在你已经安装了 ruby 和 rails 以及 devkit
rails new <project name>
cd <project name>
bundle install
rails s
http://localhost:3000 (在您的浏览器中)
上面写着“欢迎加入”
关于ruby-on-rails - 在 Windows 中，rails s 给出了 3 个不同的错误，我修复了一个并得到了更多，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30448157/
