如何指定Devkit的路径？

Question

我在Windows 7 x64上,我正在尝试从头开始安装Ruby on Rails.我刚刚安装了RubyInstaller 1.9.3-p429,现在刚刚运行了DevKit-tdm-32-4.5.2-20111229-1559-sfx.做完之后ruby dk.rb install --force.我试着测试它是否设置正确但遇到:

c:\DevKit>gem install RedCloth --platform=ruby
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
The system cannot find the path specified.
ERROR:  Error installing RedCloth:
        ERROR: Failed to build gem native extension.

        C:/Ruby193/bin/ruby.exe extconf.rb
checking for main() in -lc... no
creating Makefile


Gem files will remain installed in C:/Ruby193/lib/ruby/gems/1.9.1/gems/RedCloth-4.2.9 for inspection.
Results logged to C:/Ruby193/lib/ruby/gems/1.9.1/gems/RedCloth-4.2.9/ext/redcloth_scan/gem_make.out

这种情况发生在需要Devkit的所有宝石上.我想我必须设置指定的路径,但我不知道这意味着什么.我该怎么做或这里真正的问题是什么？

PS

一点点背景.我确实安装了RailsInstaller但是我得到了同样的错误所以我删除了所有内容.我也安装了NodeJ,但也删除了.我完全删除了PATH变量,从头开始.

UPDATE

尝试RailsInstaller给了我这个错误:

$ gem install json -v 1.8.0
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
The system cannot find the path specified.
ERROR:  Error installing json:
        ERROR: Failed to build gem native extension.

我讨厌碰到一个旧线程,但我希望添加答案以防万一其他人过来(可能因为这是谷歌搜索"Devkit PATH错误"的顶部).

将DevKit解压缩到永久目录后,在导航到shell中的install文件夹并输入"ruby dk.rb init"命令后,请确保实际执行下一步并安装 devkit.在init命令之后,运行"ruby dk.rb install",这应该解决许多类似的问题.
