Fetching gem metadata from https://rubygems.org/..
Could not find gem 'rmagick v 2.13.1 (>= 0) x86-mingw32' in the gems available o
n this machine.

嗨,我在运行bundle install时收到消息,下面是我的gemsfile

source 'https://rubygems.org'

gem 'rails', '3.2.6'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3'

gem 'carrierwave'
gem 'rmagick v 2.13.1'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
 gem 'sass-rails',    '~> 3.2.3'
gem 'coffee-rails',  '~> 3.2.1'

# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platforms => :ruby

gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

# To use ActiveModel has_secure_password
 gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
 # gem 'jbuilder'

# Use unicorn as the app server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

 # To use debugger
# gem 'debugger'

gem 'will_paginate','~> 3.0'

还有另一种方法在Rails 3中安装RMagick gem吗？我安装了carrierwave,需要使用rmagick.我可以在没有rmagick的情况下使用carrierwave吗？

Answer 1

你需要Gemfile稍微改变一下.

gem 'rmagick', '2.13.1'

您还需要imagemagick在系统上安装.rmagick要求imagemagick

您可以通过安装yum,apt-get或什么包管理器的操作系统使用.

需要注意的是,imagemagick在OSX 上安装有点棘手.我推荐使用homebrew

brew install -f imagemagick --disable-openmp
