我按照Octopress Documentation中的所有说明操作：
sddhrthrt@thinkpad:~/octopress$ rake generate

我承认，我从未参与Ruby工作。因此，我不太愿意解读错误。谷歌搜索也没有产生任何我能理解的东西。
修改
在答案中提到，我安装了rbenv，然后安装了ruby 1.9.3-p327。我回到~/octopress然后跑了bundle install并说它已经安装了所有宝石（当我有红宝石1.8x时我已经这样做了）。现在rake给了我这个错误：
sddhrthrt@thinkpad:~/octopress$ rake --trace
rake aborted!

我应该重新使用捆绑所有的宝石吗？我不明白。
答案 0 :(得分：3)
试试
$ rvm use 1.9.3
在您网站的根文件夹中。注意，1.9.3是您的Ruby版本。
然后我想当你运行
$ rake watch
或
$ rake preview
现在可以使用。
因此，对于rbenv，请尝试：
$ rbenv global 1.9.3-p327
或者您可以改为使用local。

我认为问题在于过时的Ruby。根据这个：https://github.com/imathis/octopress/issues/142你应该使用Ruby 1.9（稳定版本现在是1.9.3-p327）。您可以直接从Ruby站点获取此信息，但我建议使用RVM（或rbenv）来设置您的Ruby环境。
您可以在此处找到如何在您的包装盒上安装RVM的指南：https://rvm.io/rvm/install/
然后安装Ruby 1.9.3将非常简单：
rvm install 1.9.3
rvm --default 1.9.3
rvm reload
然后，您必须在Octopress根目录中安装bundle install（以获取bundler：gem install bundler）的所有依赖项。
修改
Octopress项目根目录中的.rvmrc表示它需要Ruby 1.9.3：https://github.com/imathis/octopress/blob/master/.rvmrc

您是否错过了rbenv配置的第3步？
$ echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
