Today, I’ve updated my version of Jekyll from 0.12.1 to 1.0.2. I’ll detail the procedure I followed to do it. Most of the commands have to be ran as root.
Clean the project
You will need to start by deleting the Gemfile.lock file, so it can be re-generated with the correct version numbers.
Update the Jekyll gem
$ gem update jekyll
Update the Kramdown gem
If you’re using Kramdown as your markdown parser, you’ll need to update it:
$ gem update kramdown
Disable jekyll-press
If you’re using jekyll-press to compress the generated output files, this plugin doesn’t seem to be compatible with Uglifier 2.0.1 (one of the gems used by it). When I tried to run a local instance of Jekyll, I got this error:
error: Invalid option: inline_script
So you’re going to have to disable it for now (I haven’t found a solution yet). Edit your Gemfile and remove (or comment) the line:
gem 'jekyll-press'
Retrieve all the gem dependencies
$ bundle
Remove the automatic re-generation parameter
In your _config.yml file, remove (or comment) the line:
auto="true" # or "false"
Run Jekyll
Now you should be able to run Jekyll. To launch a local instance, use:
$ jekyll serve
instead of:
$ jekyll --server
To run it with auto-regeneration, run:
$ jekyll serve --watch
