问题是mongoids save!动作引发的以下错误.

Mongoid::Errors::Validations: Validation failed - Img failed to be processed.
~/.rvm/gems/ruby-1.8.7-p249/gems/mongoid-2.0.0.rc.7/lib/mongoid/persistence.rb:234:in `fail_validate!'
~/.rvm/gems/ruby-1.8.7-p249/gems/mongoid-2.0.0.rc.7/lib/mongoid/persistence.rb:75:in `save!'
./app.rb:29:in `POST /upload'

设置主要是以下内容:

require "sinatra"     # 1.1.2
require "mongoid"     # 2.0.0.beta.19
require "rmagick"     # 2.12.2
require "carrierwave" # 0.5.1
require "carrierwave/orm/mongoid"
require 'carrierwave/processing/rmagick'
....


Mongoid.database = Mongo::Connection.new('somehost', 1234).db('test')

class Uploader < CarrierWave::Uploader::Base
  include CarrierWave::RMagick
  storage :file

  def store_dir
    "uploads"
  end

 process :resize_to_fit => [80, 80]
end


class Image
  include Mongoid::Document

  mount_uploader :img, Uploader
end


....

post '/upload' do
  @img = Image.new
  @img.img = …

我正在尝试使用rvm在运行Snow Leopard的Mac上安装Ruby 1.9.2.

我的.bash_profile包含

ARCHFLAGS="-arch x86_64"

要安装ruby,我运行:

rvm install 1.9.2 -C --enable-shared

编译时出错.这是make.error.log:

[2010-01-20 10:03:00] make 
ld: in /usr/local/lib/libxml2.2.dylib, file is not of required architecture
collect2: ld returned 1 exit status
make[1]: *** [../../.ext/i386-darwin10.2.0/tcltklib.bundle] Error 1
make: *** [mkmain.sh] Error 1

编辑:

我从源代码安装了readline并尝试了这样的安装:

rvm install 1.9.2 -C --enable-shared,--with-readline-dir=/usr/local 

这导致了与以前相同的错误.

rcltklib.bundle文件的位置是:

/usr/local/lib/ruby/1.8/i686-darwin9.7.0/tcltklib.bundle  

(我认为这个文件是Ruby OSX安装的一部分)
