安装蓝布 - 配置选项？

Question

我尝试输入

来安装蓝布宝石

gem install bluecloth

但是当我这样做时，我收到以下错误消息：

checking for random()... *** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=/Users/cyrusstoller/.rvm/rubies/ruby-1.9.2-p136/bin/ruby
    --with-rdiscount-dir
    --without-rdiscount-dir
    --with-rdiscount-include
    --without-rdiscount-include=${rdiscount-dir}/include
    --with-rdiscount-lib
    --without-rdiscount-lib=${rdiscount-dir}/lib

我应该提供哪些选项？

宝石安装蓝布

Answer 2

尝试在Ruby 2.2.3下安装bluecloth 2.0.11时遇到了同样的问题。事实证明Ruby 2.2.3太新了。回到Ruby 2.1.5解决了这个问题。

检查.ruby-version。
