问题描述
我正在尝试运行的协作项目中遇到pdf-writer gem问题，我正在使用 RVM ， Ruby 1.9.2p180 ， Rails 3.1.0 位于 Ubuntu 10.10 。
我使用Bundler创建了一个新的 gemset 来安装所需的gem，但是当我尝试运行该应用程序时，我得到了下面的错误;

问题出在 pdf-writer-1.1.8 / lib / pdf / writer.rb：712 content =％PDF - ＃{@ version} \％％ÏÓ\\\
会很棒，我试图谷歌的错误，但我还没有找到任何具体的PDF编写器....
解决方案 pdf-writer 与Ruby 1.9不兼容。有一个分支是：
将Gemfile中的 pdf-writer 行更改为：
gem'pdf-writer'，：git => 'git：//github.com/metaskills/pdf-writer.git'
I have a problem with the pdf-writer gem on a collaborative project I'm trying to run, I'm using RVM, Ruby 1.9.2p180, Rails 3.1.0 on Ubuntu 10.10.
I created a new gemset to install the required gems with Bundler, but when I try to run the app I get the fallowing error;

The problem is in the pdf-writer-1.1.8/lib/pdf/writer.rb:712, especifically; content = "%PDF-#{@version}\n%âãÏÓ\n"
Any suggestions would be great, I tried to Google the error but I have not found anything specific to pdf-writer....
解决方案
pdf-writer is not compatible with Ruby 1.9. There is a fork which is: https://github.com/metaskills/pdf-writer
Change the pdf-writer line in your Gemfile for:
gem 'pdf-writer', :git => 'git://github.com/metaskills/pdf-writer.git'
