Webby, Gems and Paths

ruby-talk
1

I am running an Ubuntu box, and it seems that whenever I "gem install" something
with an executable (eg. /var/lib/gems/1.8/gems/webby-0.7.2/bin/webby)
- I have to
make a link to it in /usr/local and set the +x flag before it works.
With Webby, linking
still doesn't work because it tries to load libraries with relative paths:

/usr/local/bin/webby:4:in `require': no such file to load --
/usr/local/lib/webby (LoadError)

...so I have to cd to /var/lib/gems...etc. to run it.

Is there something wrong with my gems setup? Also, once I had build my
Webby site,
I had to put "require 'rubygems'" in tasks/setup.rb before anything would work.

After that Webby seems to work very well, except for one more thing
that I cannot
resolve. When I try to create a new page:

lesliev@lesliev-laptop:/media/Storage/linux/qbe$ rake create:page about --trace
(in /media/Storage/linux/qbe)
** Invoke create:page (first_time)
** Execute create:page
rake aborted!

/usr/lib/ruby/1.8/rake.rb:1924:in `each'
/usr/lib/ruby/1.8/rake.rb:1924:in `run'
/usr/bin/rake:4

Any help?

On the webby create:page problem I was having, I can get a page
to be created if I change "top_level_tasks" to "collect_tasks":

/var/lib/gems/1.8/gems/webby-0.7.2/lib/webby/webby_task.rb:

      desc "create a new #{name}"
      task name do |t|
        raise "Usage: rake #{t.name} path" unless ARGV.length == 2

        #page = t.application.top_level_tasks.pop
        page = t.application.collect_tasks.pop

        name = ::Webby::File.basename(page)
        ext = ::Webby::File.extname(page)
        dir = ::Webby::File.dirname(page)

That works, but I do get a (superfluous?) error from Rake:
Don't know how to build task 'about'

What version of "gem" do you have installed?

$ gem --version

Okay, that was my bad. It will be fixed in the next release.

/usr/lib/ruby/1.8/rake.rb:1924:in `run'
/usr/bin/rake:4

What version of rake do you have installed? You should be running the latest (version 0.8.1 I believe).

$ sudo gem update rake

$ gem --version

0.9, I have just updated to 1.01, so perhaps that will work better.

Maybe not. The rubygems website says I should set my RUBYOPT
environment variable, so that would sort this problem out.

Ah, I have 0.7.1. Updating now...

Thanks for all your help!

Ok, everything seems to be working right now, although I had to
reinstall the Webby and BlueCloth gems (local install: "gem install
webby bluecloth"). I added the RUBYOPT environment variable and all
seems well. Webby also looks very nice so far, although I obviously
will need to learn Latin :wink:

Thanks!
