在 Ubuntu 14.04 上安装 Jekyll [英] Installing Jekyll on Ubuntu 14.04

问题描述

我在 Ubuntu 上安装 Jekyll 时遇到了一些问题.以下是我拥有的一些版本:

I've been having some issues installing Jekyll on Ubuntu. Here are some of the versions I have:

trevor~$ ruby -v
ruby 2.2.4p230 (2015-12-16 revision 53155) [x86_64-linux]
trevor~$ gem -v
2.5.1
trevor~$ rvm -v
rvm 1.26.11 (latest) by Wayne E. Seguin <[e-mail]>, Michal Papis <[e-mail]> [https://rvm.io/]

但是，当我尝试安装 Jekyll 时，出现以下错误:

However, when I try to install Jekyll, I get these errors:

trevor~$ gem install jekyll
Building native extensions.  This could take a while...
ERROR:  Error installing jekyll:
    ERROR: Failed to build gem native extension.

To see why this extension failed to compile, please check the mkmf.log which can be found here:

extconf failed, exit code 1

Gem files will remain installed in /home/trevor/.rvm/gems/ruby-2.2.4/gems/ffi-1.9.10 for inspection.

或者如果我使用 sudo:

Or if I use sudo:

trevor~$ sudo gem install jekyll
ERROR:  Error installing jekyll:
    jekyll requires Ruby version >= 2.0.0.

我已经尝试按照其他人的建议安装多个版本的 ruby​​-dev，但是这似乎也没有帮助.

I have tried installing multiple versions of ruby-dev as recommended by others with a similar issue, but this hasn't seemed to help either.

trevor~$ sudo apt-get install ruby2.2.4-dev
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package ruby2.2.4-dev
E: Couldn't find any package by regex 'ruby2.2.4-dev'

ruby2.0.0-dev 也会发生同样的情况.运行 sudo apt-get install ruby​​-dev 似乎安装了 1.9.3.4.无论如何，我仍然遇到上述相同的问题.

Same thing happens with ruby2.0.0-dev. Running sudo apt-get install ruby-dev seems to install 1.9.3.4. Regardless, I still run into the same issues above.

有什么想法吗?

编辑

这是我的 rvm 列表:

Here is my rvm list:

trevor~$ rvm list

rvm rubies

   ruby-2.0.0-p643 [ x86_64 ]
   ruby-2.2.1 [ x86_64 ]
=* ruby-2.2.4 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

我确实尝试安装了几个不同的版本.这会导致问题吗?

I did try installing a couple different versions. Would this cause a problem?
