GitHub pages without Jekyll¶
The “Hello world” described on Github Pages was easy. The -u or –set-upstream switch of git push was new to me:
$ git push -u origin master
It sets the default upstream reference.
Using Jekyll with GitHub Pages¶
The installation for github-pages did not work out of the box because it requires Ruby > 2 (and because a Ruby1.9 was already installed on my machine and because it is not possible to have two different system-wide versions of Ruby).
So I needed to learn about rbenv, a “simple per-user Ruby version manager”, i.e. the Ruby equivalent of virtualenv.
$ sudo aptitude install rbenv $ type rbenv rbenv is hashed (/usr/bin/rbenv) $ rbenv init # Load rbenv automatically by adding # the following to ~/.bash_profile: eval "$(rbenv init -)" $ echo 'eval "$(rbenv init -)"' >> ~/.bashrc (restart bash) $ type rbenv rbenv is a function
Registering a Ruby version for a project.
First I need to install the install command of rbenv (don’t ask me why this is not included out of the box):
$ sudo aptitude install ruby-build
install -l to see the available versions:
$ rbenv install -l usage: rbenv install VERSION rbenv install /path/to/definition Available versions: 1.8.6-p383 ... 1.9.3-rc1 2.0.0-dev jruby-1.6.3 ... ree-1.8.7-2012.02
The list is surprisingly long, and I am surprised to not see the currently stable version 2.2.1 (acfording to https://www.ruby-lang.org/en/downloads/).
But okay, let’s take the newes available version:
$ rbenv install 2.0.0-dev Downloading http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gz... Installing yaml-0.1.4... Installed yaml-0.1.4 to /home/luc/.rbenv/versions/2.0.0-dev Cloning https://github.com/ruby/ruby.git... Installing ruby-2.0.0-dev... Installed ruby-2.0.0-dev to /home/luc/.rbenv/versions/2.0.0-dev
As we see, this installs the given version of ruby into my home directory.
Note that the above also needs autoconf and bison:
$ sudo aptitude install autoconf bison
Selecting the Ruby version using rbenv local:
$ cd hgwork/alvatal $ rbenv local rbenv: no local version configured for this directory $ rbenv local 2.0.0-dev $ rbenv local 2.0.0-dev
Now the step 3 of following works:
$ gem install github-pages
But not out of the box:
