ruby-on-rails-3 - json gem 不会安装在 Windows 上

Question

这是我不断收到的错误。我安装了 DevKit 并按照所有说明进行操作。

gem install json -v '1.6.3'
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing json:
        ERROR: Failed to build gem native extension.

make: *** [parser-i386-mingw32.def] Error 127


Gem files will remain installed in C:/Program Files/Ruby/Ruby192/lib/ruby/gems/1.9.1/gems/json-1.6.3 for inspection.

有人对此有解决方案吗？

刚刚也遇到了这个。通过Installing dm-types on Windows. (Win7 x64) :这修复了它:

它看起来 ruby 路径中的空格正在搞砸makefile。也许尝试暂时在 Windows 上创建一个符号链接(symbolic link)，例如:

mklink /d c:\ruby "C:\Program Files (x86)\Ruby\Ruby193"

然后尝试使用 c:\ruby\bin\ruby.exe 安装。您可以在安装后删除符号链接(symbolic link)。
