Rspec error on Cent OS 4.8 and rails 2.3.4

Question

When I use "spec xxx.rb" to test certain ruby code, I got this error:

Missing these required gems:
  webrat  ~> 0.4.4

You're running:
  ruby 1.8.7.174 at /usr/local/bin/ruby
  rubygems 1.3.5 at /root/.gem/ruby/1.8, /usr/local/lib/ruby/gems/1.8

Run `rake gems:install` to install the missing gems.

And I have webrat 0.5.3 gem running already. Here's my server environment:

Operating System: CentOS 4.8 Ruby 1.8.7 i686-linux Rails 2.3.4

Anyone know what's going on?

Answer 1

It's possible that version of Webrat is incompatible with your version of rspec. Try installing that specific version as such:

sudo gem install webrat --version "=0.4.4"

Answer 2

Man!! hit the same problem (luckily figured this one out!)

You are probably using radiant and its quite likely that you have config/environments/test.rb saying:

config.gem "webrat", :version => "~>0.4.4", :lib => false

Remove the version => "~>0.4.4", and its starts working.
