I have also gone through the same problem. After doing a lot of research, I found a solution that works.
我也遇到了同样的问题。经过大量研究，我找到了一个有效的解决方案。
Run this command:
运行此命令：
pik list
It should show you
它应该告诉你
187: ruby 1.8.7 (2010-08-16 patchlevel 302) [i386-mingw32]
192: ruby 1.9.2p290 (2011-07-09) [i386-mingw32]
193: ruby 1.9.3p327 (2012-11-10) [i386-mingw32]
200: ruby 2.0.0p247 (2013-06-27) [i386-mingw32]
If it's not pointing to Ruby version 200 then run the following:
如果它不是指向 Ruby 版本 200，则运行以下命令：
pik use 200
Now run the following to enhance DevKit to your installed Ruby:
现在运行以下命令来增强 DevKit 到你安装的 Ruby：
ruby dk.rb install
Finally, run the following:
最后，运行以下命令：
gem install rails
This will install latest Rails version 4 for Ruby 2.0.
这将为 Ruby 2.0 安装最新的 Rails 版本 4。

As error message said, you need to install Ruby DevKit which can be obtained from RubyInstaller.org. (also need to check suitable Devkit version from there..)
如错误消息所述，您需要安装可从 RubyInstaller.org 获得的 Ruby DevKit。（还需要从那里检查合适的 Devkit 版本..）
And extract the DevKit zip file into somewhere (you are using windows then-> : c:\xxxx) Navigate to c:\xxxx and run "ruby dk.rb init" and then "ruby dk.rb install"..
并将 DevKit zip 文件解压缩到某处（您正在使用 windows then-> : c:\xxxx）导航到 c:\xxxx 并运行“ruby dk.rb init”，然后运行“ruby dk.rb install”..
And try to re-insall rails..
并尝试重新安装导轨..
I hope this helps,
我希望这有帮助，

github.comtells us that:
github.com告诉我们：
The path to your RUBY_INSTALL_DIR must not contain any whitespaces (like in “C:\Program Files\Ruby193”). This is very important because whitespaces in the path to your ruby installation will cause certain error messages as soon as you try to install gems which require the DevKit.
RUBY_INSTALL_DIR 的路径不得包含任何空格（如“C:\Program Files\Ruby193”）。这非常重要，因为只要您尝试安装需要 DevKit 的 gem，ruby 安装路径中的空格就会导致某些错误消息。
This solved the problem of this kind for me.
这为我解决了此类问题。

You're probably not going to like this answer but if you go:
https://github.com/oneclick/rubyinstaller/wiki/Development-Kit
like it says in the message it actually helps you quite a bit.
你可能不会喜欢这个答案，但如果你去：https:
//github.com/oneclick/rubyinstaller/wiki/Development-Kit
就像它在消息中所说的那样，它实际上对你有很大帮助。
It tells you to install the Development-Kit then cd to the directory that you put it the run “ruby dk.rb init” and “ruby dk.rb install” and when it finishes then you can run "gem install rails" and it simply works.
它告诉你安装开发工具包，然后 cd 到你放置它的目录，运行“ruby dk.rb init”和“ruby dk.rb install”，当它完成后你可以运行“gem install rails”，它简单的工作。
Easy to miss as I didn't see it the first time either
很容易错过，因为我也不是第一次看到
