Question

我正在从Peter Cooper的“从初学者到初学者的Ruby”开始学习Ruby。我在第7章。我安装了ruby 2.0。我正面临这个错误：

C:/Ruby200/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- 2.0/redcloth_scan (LoadError)

尝试运行此代码时：

require 'rubygems'
require 'RedCloth'
r = RedCloth.new("This is a *test* of _using RedCloth_")
puts r.to_html

我得到了这个结果：

ruby redcloth.rb
C:/Ruby200/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- 2.0/redcloth_scan (LoadError)
Couldn't load 2.0/redcloth_scan
The $LOAD_PATH was:

我已经安装了ruby gems和RedCloth。他们没有给我一个错误。如果有人能够对这一主题有所了解，我们将不胜感激。

Answer 1

试试这个：转到C：/Ruby200/lib/ruby/gems/2.0.0/gems/RedCloth-4.2.9-x86-mingw32/lib 并创建一个名为'2.0'的目录。然后将redcloth_scan.so从'C：/Ruby200/lib/ruby/gems/2.0.0/gems/RedCloth-4.2.9-x86-mingw32/lib'复制到'2.0'目录。

Answer 2

我使用Ruby 1.9.1安装在过去的RedCloth中。实际上我怀疑RedCloth不能与Ruby 2.0一起使用。

Answer 3

在ruby 2.x.x上，你需要编译gem。例如对于windows ruby 2.2.4：

设置DevKit（https://github.com/oneclick/rubyinstaller/wiki/Development-Kit）

运行命令窗口：

gem install RedCloth --platform = ruby

转到已安装的RedCloth路径 LIB \红宝石\宝石\ 2.2.0 \宝石\ RedCloth-4.2.9 \ lib中在那里创建一个名为“2.2”的新目录，并在其上复制文件redcloth_scan.so。

如果您使用gem RedCloth-4.2.9-x86-mingw32，则redcloth_scan.so包含ruby 1.9依赖项，并且它不适用于ruby 2.2.4。

要求'rubygems'并要求'RedCloth'不起作用。我该如何解决？
