我正在尝试运行的协作项目中的 pdf-writer gem 有问题，我正在使用RVM, Ruby 1.9.2p180, Rails 3.1.0on Ubuntu 10.10。

我创建了一个新gemset的来使用 Bundler 安装所需的 gem，但是当我尝试运行该应用程序时，我得到了休闲错误；

问题出在pdf-writer-1.1.8/lib/pdf/writer.rb:712，特别是；content = "%PDF-#{@version}\n%âãÏÓ\n"

任何建议都会很棒，我试图用谷歌搜索错误，但我没有找到任何特定于 pdf-writer 的东西......

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'

pdf-writer 的分支也适用于 Ruby 2.1，谢谢。

gem 'pdf-writer', :git => 'git://github.com/mwlang/pdf-writer.git'

我刚刚将 pdf-writer 移植到 Ruby 2.0。将请求发送到 metaskills（在之前的答案中引用）。

如果您同时需要 Ruby 2.0，请在此处找到分叉代码：

gem 'pdf-writer', :git => 'git://github.com/mwlang/pdf-writer.git'
