如何在windows8中启动RubyonRails?-HowtostartRubyonRailsinwindows8?

The ruby/rails/rubyinstaller has many bugs in Windows 8. Today still the best choice, but:

ruby/rails/rubyinstaller在Windows 8中有很多错误。今天仍然是最好的选择，但是:

• you cannot install Ruby 2.0 in Windows 8 - it's not compatible with Rails 4 in Windows 8. You need to install 1.9.3 in order to use Rails 4 (and you probally will waste some time until realize this because there's no sign of this and it's even make sense)
• 不能在Windows 8中安装Ruby 2.0——它与Windows 8中的Rails 4不兼容。要使用Rails 4，你需要安装1.9.3(你可能会浪费一些时间，直到意识到这一点，因为没有任何迹象表明这一点，甚至是有意义的)
• if you don't install Ruby in the exactly folder as is suggested, (e.g.: if you install in something like "d:\my apps\ruby"), it won't work, because the installer have trouble dealing with special characters, with whitespaces in the path, with more than 8 characters in the folder name (reminds me the old ms-dos), and I guess that some lines in the source-code has this default path explicitly written.
• 如果你不完全文件夹中安装Ruby作为建议,(例如:如果你安装在类似“d:\ app \ Ruby”),它不会工作,因为安装程序无法处理特殊字符,空格的路径,有超过8个字符的文件夹名称(提醒我旧的ms - dos),我想这几行源代码的默认路径明确地写。
• if you don't install the dev-kit manually via command-line, it won't work.
• 如果不通过命令行手动安装dev-kit，那么它将无法工作。
• even that you have a 64bits OS you need to install the 32bits version of Devkit compiled in 32bits - at least now they warn this in the main page (3 months ago you need to discover this in the hard way).
• 即使你有一个64位的操作系统，你也需要安装32位版本的Devkit——至少现在他们在主页上警告你这一点(3个月前你需要用困难的方式发现这一点)。
• don't forget to ALWAYS call devkitvars.bar before the first Rails/gem command in the cmd
• 别忘了总是打电话给devkitvars。在cmd中的第一个Rails/gem命令之前
• yes, installing gems will generate "lib" errors - there's nothing that you can do, just ignore them
• 是的，安装gems将会产生“lib”错误——没有什么可以做的，只是忽略它们
• finally, Windows 8 Javascript it's incompatible with Rails 4 - you need to change the runtimes.rb of "execjs" gem. The bugged line is the "JScript = ExternalRuntime.new ...". You need to remove the "//U" of ":command" and change the ":encoding" from "UTF-16LE" to "UTF-8".
• 最后，Windows 8 Javascript与Rails 4不兼容——您需要更改运行时。rb“execjs”的宝石。被窃听的行是“JScript = ExternalRuntime”。新的……”。您需要删除“:命令”的“//U”，并将“:编码”从“UTF-16LE”改为“UTF-8”。

I made a video explaining how to install Rails 4 in Windows 8. It's in portuguese, but I believe that you can follow what it's on screen: http://www.youtube.com/watch?v=SPM9nwUQqZ0

我制作了一个视频解释如何在Windows 8中安装Rails 4。它是用葡萄牙语写的，但我相信你可以看屏幕上的内容:http://www.youtube.com/watch?v=SPM9nwUQqZ0

You don't need any SDK. Install ruby itself:

不需要任何SDK。安装ruby本身:

http://rubyinstaller.org/

http://rubyinstaller.org/

This will also install RubyGems (which is the dependency manager) and finally install Rails using RubyGems:

这也将安装RubyGems(它是依赖项管理器)，最后使用RubyGems安装Rails:

gem install rails

And you're good to go!

你可以走了!

Avoid windows as your development server because windows does not have to much library support for Rails application.

避免使用windows作为开发服务器，因为windows对Rails应用程序不需要太多的库支持。

Playing at Ubuntu with Rails is like driving Ferrari .... I am agree with @Pavling suggestion about VM having Ubuntu12.04 LTS. I am also using the same way.

在Ubuntu用Rails就像驾驶法拉利....我同意@Pavling关于VM有Ubuntu12.04 LTS的建议。我也在用同样的方法。

If you can track down an old version of instant rails...you may be ok! It seems to be somewhat self-contained and builds apps within its own little world! Unfortunately it has Ruby version 187, Instant Rails 2.0 It seems to work ok!

如果你能找到一个老版本的即时rails…你会好的!它似乎有点自成一体，在自己的小世界里构建应用程序!不幸的是，它有Ruby版本187、Instant Rails 2.0，看起来运行良好!
