Mongrel and Snow Leopard

Posted by Lee on November 20, 2009 in Technical Development - (0 Comments)

So the ongoing saga of upgrade woes continues… You would think that “sudo gem update” should take care of upgrading all my old gems in Snow Leopard with all its 64-bit glory…

Nope.

It started when “ruby script/server” started WebBrick instead of Mongrel. That’s odd, but I figure I could work around it by just running “sudo gem install mongrel” again.

Unfortunately, that didn’t do the trick. So I tried summoning Mongrel directly:

mongrel_rails start

and I got this in return:

/Users/.../.gem/ruby/1.8/gems/mongrel-1.1.5/bin/../lib/http11.bundle: dlopen(/Users/.../.gem/ruby/1.8/gems/mongrel-1.1.5/bin/../lib/http11.bundle, 9): no suitable image found.  Did find: (LoadError)

 /Users/.../.gem/ruby/1.8/gems/mongrel-1.1.5/bin/../lib/http11.bundle: no matching architecture in universal wrapper - /Users/.../.gem/ruby/1.8/gems/mongrel-1.1.5/bin/../lib/http11.bundle

 from /Library/Ruby/Site/1.8/rubygems/custom_require.rb:31:in `require'

...

Luckily, Google saves the day and I found this: http://stackoverflow.com/questions/1350486/ruby-on-rails-staring-mongrel-server

I ran the following commands and it all worked as advertised. Phew, that one was easy.

sudo gem uninstall mongrel

sudo gem uninstall fastthread

sudo gem install mongrel

MySQL, Rails and Snow Leopard

Posted by Lee on November 18, 2009 in Technical Development - (0 Comments)

Ruby on Rails

After much hesitation, I took the dive and upgraded to Snow Leopard today. I ran into some ruby and MySQL errors, but other early adopters in our dev team had already prepared me for that. However, I would soon run into an issue that got me stumped. It turned out that I had forgotten something really simple.

So I had reinstall MySQL 64-bit and updated all my gems, but a particular mysql gem would refuse to reinstall.

There was this helpful document that several devs on my team sent me: http://stackoverflow.com/questions/991708/rails-mysql-and-snow-leopard

Unfortunately, I would get the following error even executing the recommended solution:

After several frustrating moments of poking around, a helpful fellow developer pointed out that “mysql” was not in my path. Duh!

I guess I just committed a newbie linux mistake. A quick update to .profile to include “/usr/local/mysql/bin” later, and the above command works perfectly now!

Here’s what I added to my .profile:

#Add mysql to path

export PATH=/usr/local/mysql/bin:$PATH

Hopefully that’s the last of my upgrade issues. :)
