在Windows上安装RubyInstaller和DevKit后,无法安装rdiscount gem [英] Can't install rdiscount gem after installing RubyInstaller and DevKit on Windows
问题描述
我在尝试在Windows 7机器上设置RoR时出现了一些错误。我使用RubyInstaller和DevKit安装了Ruby。在他们的说明中,执行 gem install rdiscount --platform = ruby
来确保它的安装正确。我得到以下错误:
I'm having some errors trying to set up RoR on my Windows 7 machine. I installed Ruby with the RubyInstaller and DevKit. In their directions it says to execute gem install rdiscount --platform=ruby
to ensure that it's installed correctly. I get the following error:
C:\Windows\system32>cd ../../DevKit
C:\DevKit>gem install rdiscount --platform=ruby

我试过此建议,并删除了重复的 libiconv-2.dll
文件,但问题仍然存在。有什么建议吗?
I've tried this suggestion, and removed a duplicate libiconv-2.dll
file but the problem is persisting. Any suggestions?
推荐答案
目前,RDiscount在Windows上被破解,请参阅 issue#74 at GitHub
At this time, RDiscount is broken on Windows, see issue #74 at GitHub
如果您安装了Ruby和DevKit,可以安装 json
或 RedCloth
等其他宝石来验证它是否正确编译:
If you have installed Ruby and DevKit, then you can install other gems like json
or RedCloth
to verify it compiles properly:
gem install json --platform=ruby
gem install RedCloth --platform=ruby
