Merb on Windows: PEBKAC! (dependency and user error)
After my last merb post Ezra left a comment with some concrete suggestions to move forward with getting merb working on Windows. My next post will cover that exact topic but I wanted to create a post to captute the stack traces of the errors I hit when trying to get merb running.
The first was a dependency issue. Merb requires json but I did not have it installed. I think the merb gem should have noted this dependency but honestly I don’t understand gems enough to know for sure. The output of the merb command and call stack is:
C:\InstantRails\ruby\merb>merb
Merb started with these options:
—
:query_string_whitelist: []
:reloader: true
:environment: development
:merb_root: C:/InstantRails/ruby/merb
:exception_details: true
:cache_templates: false
:reloader_time: 0.5
:host: 0.0.0.0
:use_mutex: true
:port: “4000″
:session_id_cookie_only: true

I fixed this by installing json 1.1.1 (mswin32).
C:\InstantRails\ruby\merb>gem install json
Select which gem to install for your platform (i386-mswin32)

4. json 1.1.0 (ruby)
5. Skip this gem

With the dependencies resolved I re-ran merb but hit another error message. I’ll give you the output and call stack first and see if you see the problem:

See it yet?
Require failed to find the file C:/InstantRails/ruby/merb/config/merb_init.rb. But why?
Because I’m an idiot :). I ran the merb command from the wrong directory. I needed to move to the application directory at which point I re-ran merb and …
Wait for the next post!
