Question

我尝试按照文档安装octopress，并在此过程中遇到此错误。（在'bundle install'之后）

尝试手动重新安装但没有成功。

An error occurred while installing rdiscount (2.0.7.3), and Bundler cannot continue.
Make sure that `gem install rdiscount -v '2.0.7.3'` succeeds before bundling.

我很确定它真的很简单，只是我现在太累了......如果我明白了，我会更新帖子而不让任何人浪费时间用它。

安装了Mac Os X山狮和红宝石1.9.3。

Answer 1

我无法使用rdiscount 2.0.7.3在Mac 10.8.5上安装ruby 1.9.2-p320-mri。我能够在rdiscount下安装ruby 2.0.0-p247，以防任何人帮助。

Answer 2

对不起来一个较旧的线程，但我在Windows 7 x64上使用ruby 2.0.0和rails 4遇到了同样的问题。难倒，尝试安装任何版本的rdiscount并没有任何效果。发现它是Avast阻止某些东西在终端中运行。禁用它10分钟，它工作100％罚款。

未能安装rdiscount-2.1.6
