jekyll installation ubuntu: gem验证

Question

我跟踪本教程，允许在我的液滴上托管Jekyll。我所有的东西都在我的机器上工作，现在把所有的东西都安装在数字海洋上。

apt-get install git-core
curl -L https://get.rvm.io | bash -s stable --ruby=2.0.0

到目前为止还不错：

# sudo gem install jekyll
Successfully installed jekyll-1.3.0
1 gem installed
Installing ri documentation for jekyll-1.3.0...
Installing RDoc documentation for jekyll-1.3.0...

然后，当我试图对jekyll做一些事情时，我会遇到一个错误：

root@jackrabbit:~# jekyll
/usr/lib/ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find jekyll (>= 0)    amongst [bundler-1.3.5, bundler-unload-1.0.2, executable-hooks-1.2.6, liquid-2.5.4, rake-    10.1.0, rubygems-bundler-1.4.2, rvm-1.11.3.8] (Gem::LoadError)

from /usr/lib/ruby/1.9.1/rubygems.rb:1231:in `gem'
from /usr/local/bin/jekyll:22:in `<main>'

我查了宝石清单：

root@jackrabbit:~# gem list

*** LOCAL GEMS ***

bigdecimal (1.2.0)
bundler (1.3.5)
bundler-unload (1.0.2)
executable-hooks (1.2.6)
io-console (0.4.2)
json (1.7.7)
liquid (2.5.4)
minitest (4.3.2)
psych (2.0.0)
rake (10.1.0, 0.9.6)
rdoc (4.0.0)
rubygems-bundler (1.4.2)
rvm (1.11.3.8)
test-unit (2.0.0.0)

我看得出来杰基尔不在那里。我做错了什么？还有其他方法确保jekyll在ubuntu上正确安装吗？

编辑：

当重新安装jekyll时，我现在得到以下新错误：

root@jackrabbit:~# gem install jekyll
Building native extensions.  This could take a while...
ERROR:  Error installing jekyll:
ERROR: Failed to build gem native extension.

/usr/local/rvm/rubies/ruby-2.0.0-p353/bin/ruby extconf.rb

Gem files will remain installed in /usr/local/rvm/gems/ruby-2.0.0-p353/gems/fast-stemmer-1.0.2 for inspection.
Results logged to /usr/local/rvm/gems/ruby-2.0.0-p353/gems/fast-stemmer-1.0.2/ext/gem_make.out

这可能有助于理解这个问题。

Answer 1

Jekyll在ubuntu红宝石1.9.3中工作得很好

# for Ubuntu 12.04
sudo apt-get update
sudo apt-get install ruby1.9.1 ruby1.9.1-dev \
  rubygems1.9.1 irb1.9.1 ri1.9.1 rdoc1.9.1 \
  build-essential libopenssl-ruby1.9.1 libssl-dev zlib1g-dev

# for Ubuntu 14.04
sudo apt-get update
sudo apt-get install ruby ruby1.9.1-dev ri1.9.1 node-js

那你只需要安装Jekyll

sudo gem install bundler
sudo gem install jekyll
