Installing Publify with bundle install, error on bluecloth gem

Question

I'm trying to install Publify web blog CMS 6.0.9 for Ruby on Rails 3.1 on Windows.

Every time I try to bundle install Publify, I get the same error message when installing the bluecloth gem:

C:\Users\Lunasea\Downloads\typo-6.0.9>gem install bluecloth

Gem files will remain installed in C:/RailsInstaller/Ruby1.9.2/lib/ruby/gems/1.9
.1/gems/bluecloth-2.2.0 for inspection.
Results logged to C:/RailsInstaller/Ruby1.9.2/lib/ruby/gems/1.9.1/gems/bluecloth

I already tried to install the gem alone or simply to install the latest version, but it gives always the same result.

I'm using the standard generated database.yml.

Answer 1

Windows is not the greatest environment to run rails under. This is a good example. See this link for more info.

Answer 2

The header files in 2.2.0 prevents bluecloth from compile on windows. However, you can patch it by yourself:

1. Run gem install bluecloth -v '2.2.0' if you haven't already

2. Apply this patch on bluecloth.h file, on my machine it is located in

   H:\Ruby193\lib\ruby\gems\1.9.1\gems\bluecloth-2.2.0\ext\bluecloth.h

3. Go to bluecloth 2.2.0 directory, for example

   H:\Ruby193\lib\ruby\gems\1.9.1\gems\bluecloth-2.2.0

4. Run rake gem (this may require to install some additional gems).

   Then you should see .gem file created in

   H:\Ruby193\lib\ruby\gems\1.9.1\gems\bluecloth-2.2.0\pkg\bluecloth-2.2.0.gem

5. Open this directory and install the patched gem:

   gem install bluecloth-2.2.0.gem --platform=ruby
