Rmagick：'需要'：没有这样的文件来加载 - RMagick（LoadError）

Question

当我在轨运行在我的lib文件夹命令红宝石billede.rb我得到的错误：

C:\Rails\myapp\lib>ruby billede.rb 
C:/Ruby192/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': 
no such file to load -- RMagick (LoadError) 
     from C:/Ruby192/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:i 
n `require' 
     from billede.rb:2:in `<main>' 

我Billede .rb：

class Billede 
require 'rubygems' 
require 'RMagick' 

if !ARGV[0] 
    puts "Usage: watermark /image.png" 
    exit 
end 

image = Magick::Image.read(ARGV[0]).first 

mark = Magick::Image.new(image.columns, image.rows) 

gc = Magick::Draw.new 
gc.gravity = Magick::CenterGravity 
gc.pointsize = 32 
gc.font_family = "Helvetica" 
gc.font_weight = Magick::BoldWeight 
gc.stroke = 'none' 
gc.annotate(mark, 0, 0, 0, 0, "Watermark\nby\nRMagick") 

mark = mark.shade(true, 310, 30) 

image.composite!(mark, Magick::CenterGravity, Magick::HardLightCompositeOp) 

out = ARGV[0].sub(/\./, "-wm.") 
puts "Writing #{out}" 
image.write(out) 
end 

我已经安装了RMagick。

安装宝石时进行更新。

在我的Gemfile我：

gem "rmagick", :require => 'RMagick' 

当运行捆绑安装：

Answer 1

在Rails项目外部脚本应如下运行：

bundle exec lib/billede.rb <params> 

（使确定你在Gemfile中有gem 'RMagick'）

在出现任何依赖性问题的情况下，您将获得更多描述性输出。

Answer 2

如果您使用的捆扎机（当您使用您使用Rails的捆扎机，太），你需要RMagick添加到您的Gemfile。 Bundler只会将捆绑的宝石加载到您的环境中。

的Gemfile

source :rubygems 

# loads of other stuff 

gem 'rmagick' 

然后运行

bundle install 

，你应该是好去

Answer 3

您需要首先安装imagemagic：

sudo apt-get install libmagickwand-dev imagemagick 

然后添加红宝石包装您的Gemfile：

gem 'rmagick' 

最后告诉捆扎机下载rmagic：

bundle install
